Using the electron configuration flow diagram below what is the correct electron configuration for chlorine atomic number 17

Cl₁₇ = 1s² 2s² 2p⁶ 3s² 3p⁵

Explanation:

Electronic configuration:

Cl₁₇ = 1s² 2s² 2p⁶ 3s² 3p⁵

Properties of chlorine:

Chlorine is present in group seventeen.

It is halogen element. its atomic number is seventeen.

It has seven valance electrons.

It is greenish-yellow irritating gas.

Its melting point is 172.2 K

Its boiling point is 238.6 K

It is disinfectant and can kill the bacteria.

It is also used in manufacturing of paper, paints and textile industries.

When combine with hydrogen it form acids.

H₂ + Cl₂  → 2HCl

it is highly electronegative and most reactive element.

When combine with metals it form salts such as sodium chloride, magnesium chloride.

2Na + Cl₂  →  2NaCl

Mg + Cl₂ → MgCl₂
