Question

Which of the following are descriptive of the neutral atom with the electron configuration of 1s22s22p3?

Answer 1

- It is in its ground state.

- It is an atom of Nitrogen.

- It has 3 electrons in its highest energy sublevel.

Answer 2

Answer : The correct options are,

It is in its ground state.

It is an atom of nitrogen.

Explanation :

The given electronic configuration is, $1s^22s^22p^3$

The number of electrons = 2 + 2 + 3 = 7

As we know that the number of electrons is equal to the atomic number of an element.

Atomic number = 7

And as we know that the nitrogen is the element having the atomic number 7. Nitrogen is the neutral element that means it is in its ground state. And it has 5 electrons in its highest energy sub-level.

Or its electronic configuration can also be written as, $[He]2s^22p^3$

Hence, the correct options are, It is in its ground state and It is an atom of nitrogen.
