Recall that atoms are the basic building blocks of matter.

Atoms are made up of much smaller particles called protons, neutrons, and electrons.

For example, all carbon atoms have 6 protons, all atoms of nitrogen have 7 protons, and all oxygen atoms have 8 protons.

The number of neutrons in the nucleus can vary in any given type of atom.

The earth has a magnetic field around it which helps protect us from harmful radiation from outer space. The stronger the field is around the earth, the fewer the number of cosmic rays that are able to reach the atmosphere.

This would result in a smaller production of The cause for the long term variation of the C-14 level is not known.

Assumptions in the scientific community are extremely important.

Before we get into the details of how radiometric dating methods are used, we need to review some preliminary concepts from chemistry.The variation is certainly partially the result of a change in the cosmic ray production rate of radiocarbon.The cosmic-ray flux, and hence the production rate of C-14, is a function not only of the solar activity but also of the magnetic dipole moment of the Earth.4Though complex, this history of the earth’s magnetic field agrees with Barnes’ basic hypothesis, that the field has always freely decayed....Protons and neutrons make up the center (nucleus) of the atom, and electrons form shells around the nucleus.

The number of protons in the nucleus of an atom determines the element.The atomic number corresponds to the number of protons in an atom.
