Detailed explanation-1: -Before you start, take a look at carbon on the periodic table. It has an atomic number of 6. That means a carbon atom has 6 protons, 6 neutrons, and 6 electrons. Since carbon is in the second row (or second period), it has 2 electron orbits.
Detailed explanation-2: -Carbon is a chemical element. Its atomic number is 6; its atomic weight is 12.011. It is a group IVA element, residing between boron and nitrogen on the periodic table, and it has 6 protons, 6 neutrons, and 6 electrons.
Detailed explanation-3: -The atomic number of carbon is 6 and the atomic mass is 12.01gmol-1.
Detailed explanation-4: -The number of protons define the identity of an element (i.e., an element with 6 protons is a carbon atom, no matter how many neutrons may be present).
