Question

when magnesium combines with chlorine, it loses 2 electrons. what is the charge of magnesium?
select one:
a. +2
b. 0
c. -2
d. -4
sodium and bromine form an ionic bond. the resulting compound, sodium bromide, is held together because...
select one:
a. oppositely charged ions attract.
b. electrons are shared.
c. protons stay in the nucleus
d. positively charged ions attract.

Explanation:

For the first question: A neutral atom has equal protons (positive) and electrons (negative). Losing 2 negative electrons leaves a net positive charge of +2.
For the second question: Ionic bonds form when atoms transfer electrons, creating oppositely charged ions. These ions are held together by electrostatic attraction between opposite charges.

Answer:

1. a. +2
2. a. oppositely charged ions attract.
