Carbon (from Latin: carbo coal) is a chemical element with symbol C and atomic number 6. On the Periodic table, it is the first (row 2) of six elements in column (group) 14, which have in common the composition of their outer electron shell. It is nonmetallic and tetravalent âmaking four electrons available to form covalent chemical bonds.
The atomic number is what distinguishes one element from another in nature. For example, hydrogen has an atomic number of 1. An atom of hydrogen has a single proton and a single electron. Helium has an atomic number of 2.A single helium atom has 2 protons and 2 electrons. Copper has an atomic number of 29, so it contains 29 protons and 29 electrons.The atomic weight (sometimes called atomic mass) of an atom is approximated by the sum of the number of protons and the number of neutrons in the nucleus of the atom.he atomic number is what distinguishes one element from another in nature. For example, hydrogen has an atomic number of 1. An atom of hydrogen has a single proton and a single electron. Helium has an atomic number of 2.
