Carbon dating in the news
Archaeologists now have new tools for studying the development of medieval villages and the transformation of the historical landscapes surrounding them. Radiocarbon dating is a key tool archaeologists use to determine the age of plants and objects made with organic material.
The atomic number corresponds to the number of protons in an atom.
The number of protons in the nucleus of an atom determines the element.
For example, all carbon atoms have 6 protons, all atoms of nitrogen have 7 protons, and all oxygen atoms have 8 protons.
Atoms are made up of much smaller particles called protons, neutrons, and electrons.
Protons and neutrons make up the center (nucleus) of the atom, and electrons form shells around the nucleus.
