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

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.
