d. the atom loses 2 electrons to have a total of 14.

C. The atom gains 2 electrons to have a total of 18.

Explanation:

Step by step explanation:

A neutral Sulfur-36 atom has 16 electrons and the 16 protons (as the Sulfur atom is neutral, it should have same number of electrons as that of protons). The number of neutrons in Sulfur-36 is equal to total mass of sulfur (which is 36) minus the number of protons (which is 16), resulting in 20 (36-16=20). If sulfur-36 becomes  -2 charged ion, it needs to gain a negatively charged particles (i.e. electrons). An electron has a negative charge of -1. So sulfur-36 atom needs to gain 2 electrons to become -2 charged ion. Therefore the correct answer choice is C.

the answer is neither ball has a charge.

because if they were both positively charged, they will repel each other.

if they were positively and negatively charged, they will seek.
