Elements that are characterized by the filling of p orbitals are classified as
a. groups 3a through 8a
b. transition metals
c. inner transition metals
d. groups 1a and 2a

Answer : The correct option is, (a) Groups 3A through 8A

Explanation :

The general electronic configurations of :

Group 1A :

Group 2A :

Group 3A :

Group 4A :

Group 5A :

Group 6A :

Group 7A :

Group 8A :

Transition metal :

Inner transition metal (Lanthanoids) :

Inner transition metal (Actinoids) :

From the general electronic configurations, we conclude that the groups 3A through groups 8A elements that are characterized by the filling of p-orbitals.

"standard molar enthalpy:

h2o ( liquid water ) : - 285.8 kj/mole

h2o ( water vapor ) : - 241.8 kj / mole.

δhrxn = - 241. 8 - ( - 285.8 )= -241.8 + 285.8 = 44.0

answer: 44.0 kj"
