Question

1. which of the following describes the charge of alkali metals?

a. it has a 1+ ion charge.
b. it has a 1- ion charge.
c. it does not have a charge.
d. it has a 2+ charge.

Explanation:

Alkali metals are in Group 1 of the periodic table. They have one valence electron, which they tend to lose to achieve a stable electron configuration. When they lose one electron, they form ions with a 1+ charge (since losing an electron, which has a negative charge, results in a net positive charge of +1). Option a states this, option b is incorrect (they lose electrons, so positive charge), option c is incorrect (they form ions with charge), and option d is incorrect (Group 2 metals have 2+ charge, not Group 1).

Answer:

a. It has a 1+ ion charge.
