Which statement is true concerning the elements in families 1 and 2? A. All the elements in families 1 and 2 have three electrons in their outer shell.
B. All the elements in families 1 and 2 need the s and p sub-levels to place their outer
shell electrons.
C. All the elements in families 1 and 2 need only 2 energy levels to place their
electrons.
D. All the elements in families 1 and 2 can place all their outer shell electrons in the s
sub-level.

The correct option is;

D. All the elements in families 1 and 2 can place all their shell electrons in the s sub-level

Explanation:

The elements in families 1 and 2 also called the group 1A and group 2A elements are known as the alkali and alkaline earth metals. The elements in the families 1 and 2 are also referred to as the s-block elements as they have their valence electrons which are 1 and 2 respectively, in the s-orbital or s sub-level

Due to their low ionization energy, and the ease with which they donate their valence electrons, elements of the families 1 and 2 are known to be very reactive, and are found in a combined state in nature.

a is the answer
