Question

question 1 (1 point) the electronic configuration of chlorine is 1) 1s²2s²2p⁶3s²3p⁵ 2) 1s²2s²2p⁶3d²3p⁵ 3) 1s²2s²2p⁶3d⁷ 4) 1s²2s²2p⁵

Explanation:

Step1: Determine the atomic number of chlorine

Chlorine has an atomic number of \(17\).

Step2: Write the electron configuration

Using the Aufbau principle, electrons fill orbitals in order of increasing energy.
The electron configuration is \(1s^{2}2s^{2}2p^{6}3s^{2}3p^{5}\).

Answer:

1. \(1s^{2}2s^{2}2p^{6}3s^{2}3p^{5}\)
