which statement correctly compares an atom of an alkali metal with an atom of the alkaline earth metal next to it on the periodic table?\nthe alkali metal atom forms a +1 ion, while the alkaline earth metal atom forms a +2 ion.\nthe alkali metal atom forms a +2 ion, while the alkaline earth metal atom forms a +1 ion.\nthe alkali metal atom has one less shell of electrons than the atom of the alkaline earth metal.\nthe alkali metal atom has one more shell of electrons than the atom of the alkaline earth metal.

Answer

Brief Explanations:

Alkali metals have 1 valence - electron and lose it to form a +1 ion. Alkaline - earth metals have 2 valence - electrons and lose them to form a +2 ion. Atoms in the same period have the same number of electron shells.

Answer:

The alkali metal atom forms a +1 ion, while the alkaline earth metal atom forms a +2 ion.
