Answer 1

Answer:

d. ns2np3

Explanation:

In the first main group all elements have a singly occupied s orbital.

In the second main group, all elements have a doubly occupied s orbital.

In the third main group or 13th group all elements have a doubly occupied s orbital and a singly occupied p orbital.

In the fourth main group or 14th group all elements have a doubly occupied s orbital and a doubly occupied p orbital.

In the fifth main group or 15th group all elements have a doubly occupied s orbital and a triply occupied p orbital.

And so on.
