1. When metal atoms share their outermost electrons with a nonmetal, the metal and nonmetal become
A. electrically charged
B. less chemically stable
C. more chemically stable
D. O radioactive

since the atomic number is the number of protons in the nucleus, as we move to the left on the periodic table, the electrostatic pull between the nucleus and the valence electron shell decreases. as we move down a group (vertical column), the valence shell energy level gets further and further from the nucleus.

we need the questions , i may then you.

elements make up everything, and they combine to make compounds.

the answer is c
