The atomic numbers of two elements A and B are 11 and 12 respectively. Which element exhibits highest metallic property? Why? Write the molecular formula of the compounds formed when these elements combine with the element ‘Z’ having atomic number 8.

Answer»

A – 11 – Sodium
B – 12 – Magnesium
Sodium exhibits highest metallic property. Because metallic character decreases across a period.
Z - 8 – Oxygen
(When sodium combines with oxygen sodium oxide is formed when magnesium combines with oxygen magnesium oxide is formed). The molecular formula of the compounds formed are Na2O & 2MgO
