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

answer: the value of enthalpy change will be -152.80 kj.

solution:

pressure = 1atm , temperature = = 298 k

given that pressure and temperature are same in both gases , the number of moles of both gases can be determined by the ideal gas equation.

according to reaction 3 moles no are reacting with 1 mol of ,then 0.49 mol of no will react with moles of ozone that is 0.16 moles of ozone. since, no is limiting reagent and is an excessive reagent.

enthalpy change for the reaction between the given volumes of the gases is :
