Magnesium (Mg) is located to the right of sodium (Na) because Mg has....
a.) Less electrons
b.) Less protons
c.) Both a.) And b.)
d.) None of the above.

Magnesium is located to the right of sodium because magnesium has more protons. Hence, option D is correct.What is the valency of an electron?Atoms are divided into particles :ElectronProtonNeutronElectrons present in the outermost shell of an atom are the valency of the atom.When we move left to right in the period number of valence electrons increases but across a group, valance electrons remain constant as we move from top to bottom.According to the question, magnesium is located to the right of sodium because it has more protons and as we know that in the modern periodic table elements are arranged according to their increase in their atomic number. So magnesium has more protons means it has a high atomic number.Hence, magnesium has the atomic number 12 and the atomic number of sodium is 11 that's why magnesium comes after sodium.To get more information about valency of atom :https://brainly.com/question/12744547#SPJ2

D, None of the above. Mg has more protons and electrons than Sodium.
