Question

What is the correct electron configuration for a ground-state atom with 7 electrons?

Answer 1

The ground state of the atom is its lower energy state. The correct electron configuration for a ground-state atom with 7 electrons is 1s^2 2s^2 2p^3. The powers that are exponents represent the number of electrons in the configuration and the 1s, 2s and the 2p represent the orbital.

Answer 2

We have that the Electron Configuration for Nitrogen (N)  is mathematically given as

1s^2 2s^2 2p^3.

The Electron Configuration for Nitrogen (N)

Question Parameters:

a ground-state atom with 7 electrons

Generally , Nitrogen is the element with a total of 7 electrons.

In writing the electron configuration for elements we first consider the orbitals in the appropriate progression

Therefore

1s^2 2s^2 2p^3.
