Find sulfur s and magnesium mg on the periodictable below how many electrons are in the outer shell of each of these 2 elements

there is not enough info to determine the answer
sulfer has 16 mag 12
sulfer 3, mag 3
sulfer 6 mag 2

Option (d) is the correct answer.

Explanation:

According to the periodic table, both magnesium and sulfur belongs to third period.

It is known that atomic number is the number of protons present in an atom.

Also, it is known that when an atom is neutral then number of protons equal the number of electrons.

So, atomic number of magnesium is 12, that is, electronic configuration of magnesium is 2, 8, 2. Whereas atomic number of sulfur is 16, that is, electronic configuration of sulfur is 2, 8, 6.

Thus, we can conclude that in the outer shell magnesium has 2 electrons and sulfur has 6 electrons.

vanderwaal's forces of attraction are the electrostatic intermolecular forces that exist in a molecule due to the temporary or permanent dipoles that are developed in a molecule. in , the major intermolecular forces are dipole-dipole interactions as the molecule is polar (bent structure). so the vanderwaal's forces of interaction in between molecules are the permanent dipole-dipole interactions that develop due to the dipole that exists in between the polar h - s bond. the positively charged hydrogen atom is attracted towards the negative end of the dipole that is sulfur of the adjacent molecule. therefore, these forces of attraction are relatively stronger than that of london dispersion forces that exist in non polar molecules.

12 is it do you think so
