Charged particles are produced when electrons are transferred from one particle to another.

True

False

Skip.

Question 13
The rule that the first column of elements, excluding hydrogen, always loses one electron to have a +1 charge, along with the +2 rule for the second column, and the -1 rule for the next to last column are very useful when determining what elements react to form ionic compounds.

Question 18
Solid NaCl when put into water must separate into Na⁺ and Cl^- ions that can independently move around in the water.

True

False

Skip.
