Question

question 2
what happens when an element of group 2 interacts with an element from group 16?
the element from group 16 will gain two electrons from the group 2 element.
the element from group 2 will gain two electrons from the group 16 element.
both elements will share electrons
nothing will happen

Explanation:

Elements in group 2 are metals and have 2 valence - electrons. They tend to lose these 2 electrons to achieve a stable electron configuration. Elements in group 16 are non - metals and need 2 electrons to complete their octet. So, the group 16 element will gain the 2 electrons lost by the group 2 element.

Answer:

The element from group 16 will gain two electrons from the group 2 element.
