Question

Which statements describe carbon? Check all that apply.

Answer 1

The solutions would be a, b, e, f.

Answer 2

Answer;

a. atomic mass of ~ 12 amu

b. atomic number of 6

e. 6 protons, 6 neutrons

f. valence of 4

Explanation;

• Carbon is a chemical element in the periodic table. Its symbol is C.
• Carbon has an atomic number of 6, atomic number is the number of protons in the nucleus of an atom, therefore carbon has 6 protons, and since the number of electrons are equal to the number of protons in a neutral atom, then the number of electrons in carbon atom is 6.
• Carbon requires to gain or loose 4 electrons to attain a stable electronic configuration and therefore it has a valency of 4.
• The atomic mass of carbon is ≈ 12 a.m.u. Carbon is found in group 14 of the periodic table.
