The Lewis dot model of a metal atom has two dots. Which of the following is true about the atom?

It is most likely to form covalent bonds.

It has two electrons in the innermost energy level.

It requires six other atoms to form a stable compound.

It is present in the second group of the periodic table.

Answer : the statement that is true about the atom is It is present in the second group of the periodic table.

Explanation:

The Lewis dot model shows the number of valence electrons present in the atom.

Since the given metal has 2 dots, it indicates that the metal atom must have 2 electrons in its outermost shell.

Therefore option 2 : It has two electrons in the innermost energy level, is wrong because it contains 2 electrons in the outermost energy level

Option 1 : It is most likely to form covalent bonds is also wrong because a metal atom always forms ionic bond

Option 3 : It requires six other atoms to form a stable compound, is also wrong as the metal can form a stable compound by donating its 2 electrons to a non metal.

On periodic table, representative elements are arranged in groups based on their valence electrons. Therefore by knowing the outermost electrons, we can predict the group in which the element can be categorized.

Since the given metal atom contains 2 electrons, it must be present is second group.

Therefore the statement that is true about the atom is It is present in the second group of the periodic table.
