Question

give the full ground state electron configuration for tungsten.

Explanation:

Step1: Recall tungsten's atomic number

Tungsten (W) has an atomic number of 74, so it has 74 electrons in the ground - state.

Step2: Fill orbitals according to the Aufbau principle

We fill orbitals in the order of increasing energy: 1s < 2s < 2p < 3s < 3p < 4s < 3d < 4p < 5s < 4d < 5p < 6s < 4f < 5d < 6p.
1s can hold 2 electrons: $1s^{2}$
2s can hold 2 electrons: $2s^{2}$
2p can hold 6 electrons: $2p^{6}$
3s can hold 2 electrons: $3s^{2}$
3p can hold 6 electrons: $3p^{6}$
4s can hold 2 electrons: $4s^{2}$
3d can hold 10 electrons: $3d^{10}$
4p can hold 6 electrons: $4p^{6}$
5s can hold 2 electrons: $5s^{2}$
4d can hold 10 electrons: $4d^{10}$
5p can hold 6 electrons: $5p^{6}$
6s can hold 2 electrons: $6s^{2}$
4f can hold 14 electrons: $4f^{14}$
5d can hold 4 electrons: $5d^{4}$

Answer:

$1s^{2}2s^{2}2p^{6}3s^{2}3p^{6}4s^{2}3d^{10}4p^{6}5s^{2}4d^{10}5p^{6}6s^{2}4f^{14}5d^{4}$
