Six Elements and Three Interactions

Six Elements and Three Interactions

You can find six elements in the cells of all living things: carbon, hydrogen, nitrogen, oxygen, phosphorus, and sulfur. Without all of those elements, life, as we know it, could not exist. Living things require many other elements to perform various functions to survive, but those six elements are the building blocks of living cells. Life depends on those six elements and three interactions.

What do those elements have in common? For one thing, they are all non-metals. More important is that those six elements have stable atoms that are not radioactive. Radioactive decay of the atoms of some elements releases alpha or beta particles, which are destructive to living tissue. When those particles enter living tissue, they cause the release of high-energy particles in the cells. That destroys DNA, causing disease and mutations.

We are exposed to some radiation every day, but the amount is usually small, and our cells have a remarkable ability to repair themselves. If any of the six elements released radiation particles, life could not exist. Why are these six elements so stable? We have to consider the six elements and three interactions.

Three carefully balanced forces or interactions work within every atom to give stability. They are the strong force, the weak force, and the electromagnetic force. The strong force binds protons together in the atomic nucleus. The weak force is responsible for radioactive decay. Electromagnetic interaction between the protons in the nucleus and the electrons holds those electrons in the atomic shell while allowing chemical interactions between elements.

The key to stability is the precise balance between the three forces. A change in the value of any of the three would upset the balance, making our atoms unstable and life impossible. Was it mere luck that caused the delicate balance of those forces? Is it possible that the balance and our existence are just chance accidents? We think a better explanation is that the Creator of the universe carefully designed the six elements and three interactions.

Magnetism and Life

Magnetism and LifeOne of the things that beginning chemistry students run into very early is the fact that magnetism plays a vital role in the way electrons and atoms work. I remember one of my favorite students who whined and complained when we talked about paired electrons and their dependence on magnetism. He said, “Why does chemistry have to be so terribly complicated? I could function very nicely without magnetism, thank you.” My response was that not only could he not function without magnetism, but he could not exist without magnetism. There is an inseparable bond between magnetism and life.

Most of us are aware of magnetism in only a vague way. We know that magnets stick things to our refrigerators, and we are familiar with magnetic compasses. We have some awareness that the Earth has a magnetic field, although we don’t know how or why. The simple fact is that, without magnetism, we would not exist. In addition to that, much of what allows us to live as we do depends on magnetism. Our appliances and electronic devices work because of magnets and magnetic principles. In fact, magnetism generates the electricity we use.

Earth’s magnetism and life are connected in a way that most people don’t understand. As charged particles come toward us from the Sun and other objects in space, Earth’s magnetic field deflects them away. Without this protective shield, radiation would be so high on the Earth’s surface that life would have a very difficult time surviving. Also, magnetism is an active force in living things. Many animals migrate from one geographic area to another using Earth’s magnetic field as a guide. We have even found that tiny magnets inside our bodies can be used to see things that are invisible to X-rays and ultrasound. Magnetic resonance imaging (MRI) is an important tool available to modem science.

The reason magnetism works is because of the design of the electron. Electrons possess a magnetic field. Each electron has a north and a south magnetic pole caused by the electron’s spin. We don’t know exactly how this works, but we do know that for chemical reactions to take place, electrons must have their magnetic field in a specific alignment. This magnetic property of electrons controls all chemical reactions and makes a variety of other chemical processes possible. If an electron had all of its electrons paired up magnetically, all of its energy fields filling the atom would be totally stable. Elements that have that arrangement are called inert, and examples are helium, neon, argon, krypton, and xenon.

In some materials, there are large numbers of unpaired electrons. The energy of unpaired electrons allows these elements to be very active, and we use those materials for a variety of special purposes. Atoms strive to have all magnetic fields balanced and closed, and that is the basis of modem chemistry. When electrons flow through a wire, their alignment causes their magnetic fields to add and grow. That is the basis of the electromagnet and the Earth’s magnetic field which protects us.

The design of the atom and the way magnetism is built into elements allows the existence of matter, life, and the protective system that sustains life on Earth. The connection between magnetism and life and the complexity of this system tells us that chance is not the guiding mechanism. There are intelligence and purpose in the system that makes life possible. The design of the cosmos that functions year after year speaks eloquently of the wisdom and power of its Creator.

Chemical Elements and the Laws of Nature

Chemical Elements and the Natural Laws
We are amazed to realize that everything in the world around us is made up of fewer than 100 different chemical elements. Those elements are combined to form vast numbers of different compounds, and those compounds come together to make up everything including air, soil, plants, and our bodies.

Even more amazing is that those chemical elements are all made up of the same three particles called protons, electrons, and neutrons. The only difference between the elements is the quantity of each of the particles in their atoms. The periodic table gives an organized way to look at the elements based on the number of protons in the nucleus of each atom. It shows all of the natural elements plus more than 20 others that have been created in laboratories with particle accelerators–machines that smash atoms together.

The natural chemical elements range from hydrogen with only one proton to uranium which has 92. The periodic table, first conceived in the nineteenth century, shows which elements react similarly with other elements to form chemical compounds. The ability of the various elements to combine with other element makes possible every compound which makes up every substance on Earth.

Each atom of each element has protons in the center called a nucleus and electrons surrounding the nucleus in “shells.” The atoms of some elements also have neutrons in the nucleus. The strong interaction in the nucleus binds the protons and neutrons together. At the same time, the electrical or Coulomb force causes the protons to repel each other. As the number of protons approaches 100 or more, the repelling force overcomes the attracting force, and the atom becomes unstable. For that reason, the larger atoms only exist in the laboratory and only for very short times.

If you could add the mass of all of the protons, neutrons, and electrons in an atom, you would find that the total mass is more than the mass of the atom itself. That extra mass is found in the energy that binds the nucleus together. Einstein’s famous equation E=mc^2 indicates that matter and energy are different forms of the same thing. In other words, the extra mass has become the energy that binds the nucleus together.

Physics and chemistry are subject to laws which control all of the universe. Without those laws, the universe could not exist, and neither could science. Scientific experimentation is based on the consistency of the natural laws which came into existence when the universe was created. Science is unable by experiment to study what happened before the creation of those laws. Why do those laws exist? Why does anything exist? We believe the answer can be found in Genesis 1:1.
