As the elements in Group 1 of the Periodic Table are considered in order of increasing acomic number, the atomic radius of each successive element increases. This is primarily
due to an increase in the number of
1) neutrons in the nucleus
3) valence electrons
2) unpeired electrons
4) electron shells
the said state each atom ofan element has two valence electrons. This element
