10 points
a. 0 – it will be a neutral atom
b. +2
c. -2
d. -1​

Answer 1

Answer:

c

Explanation:

because we it gains..electrons are negative..so...minus and..2 electrons so...charge is -2

Answer 2

oxygen gains two electrons, it attains the same electron configuration as neon. Oxygen is frequently found as an O2- anion in many compounds. ... Cations are atoms that have lost electrons, so that they have an overall positive charge.
