Carbon Atomic Number



The atomic number of carbon is 6 and its atomic mass is 12. How many protons are there in the nucleus of carbon?

Carbon compounds are named according to the number of carbons present in the basic chain, the presence of single, double or triple bonds, whether or not the carbon chain forms a cyclic structure and the elements or ions that substitute for hydrogens in the chain. Carbon (C) exists as several allotropes, most commonly as Diamond or the gray-black solid Graphite. It has the atomic number 6 in the periodic table and belongs in Group 14. It is a non metal with the symbol C. Carbon gets its name from the Latin word 'carbo' meaning charcoal or coal. Isotopes There are two stable naturally occurring isotopes of carbon, carbon-12 and carbon-13. Carbon-12 makes up almost 99% of the carbon found on Earth. There are 15 known isotopes of carbon. Carbon-14 is used to date carbon based materials in 'carbon dating.' Give the ground-state electron configuration for carbon (atomic number 6) sa 82p 2 Give the ground-state electron configuration for fluorine (atomic number 9). Give the ground-state electron configuration for magnesium (atomie number 12), 4.

(A) 06 protons
(B) 12 protons
(C) 18 protons
(D) Zero protons
