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? the alkali metal atom forms a +1 ion, while the alkaline earth metal atom forms a +2 ion. the alkali metal atom forms a +2 ion, while the alkaline earth metal atom forms a +1 ion. the alkali metal atom has one less shell of electrons than the atom of the alkaline earth metal. the alkali metal atom has one more shell of electrons than the atom of the alkaline earth metal.
Answer
Brief Explanations:
Alkali metals are in group 1 and have 1 valence - electron, which they lose to form a +1 ion. Alkaline - earth metals are in group 2 and have 2 valence - electrons, which they lose 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.
