marcos and helen study the electron configurations of neutral atoms. they draw the atomic models shown. due to their electron structure, what do the two atoms have in common? a. atomic number b. mass number c. period d. family

Answer

Brief Explanations:

The number of electrons in the out - most shell (valence electrons) determines the chemical family of an atom. Atoms with the same number of valence electrons belong to the same family. In the given electron - dot models, if the outermost shell has the same number of electrons, they belong to the same family.

Answer:

D. family
