. Name any two elements of group one and write their electronic configurations. What similarity do you observe in their electronic configurations

Write the formula of oxide of any of the aforesaid  element.                                                                               

Best Answer

Ans. Ans. Two elements of group 1

Na =Sodium                          K  =Potassium

Electronic configuration of:

Na = 2, 8, 1                           K = 2, 8, 8, 1

Similarity between Na and K. Both have one electron in their outermost  shell. Thus both have one valence electron and valency one.

Oxide of Sodium   Na2O

Oxide of Potassium   K2O
