Which electron configuration matches this model? 0 1s22s2p2
0 1s²2s2p3
O 1s²2s²2p4
1s22s²2p5

1s2 2s2 2p5

is the correct answer

Explanation:

Hi there!

From the figure;

We can figure out that the atomic number is 7.

So;

Option A: 1s² 2s² 2p²

Sum of the powers of variable is just 6. So, it's not answer.

Option B: 1s²2s²2p³

Sum of the powers of variable is 7. So it's the answer

Option C: 1s²2s²2p⁴

Sum of the powers of variable is 8. So, it's not answer.

Option D: 1s²2s²2p⁵

Sum of the powers of variable is 9. So, it's not the correct answer.

Therefore, answer is option B.

Hope it helps!
