Question

Write the electron configurations of magnesium (z=12) and fluoride (z=9). Explain what electrons must be gained or lost from the atoms to form an electron configuration of a filled shell. Write the electron configuration of each ion too. Which noble gases have those electron configurations?

Expert Solution

Step 1

Magnesium (z=12) electron configuration will be [Mg]= 1s²2s²2p⁶3s²

Two electrons from 3s orbital must be a loss, to form an electron configuration of a filled shell.

After 2 electrons loss from 3s orbital, electron configuration will be

[Mg ⁺² ] = 1s²2s²2p⁶(Neon noble gas electron configurations)

[Ne] = 1s²2s²2p⁶
