Question

Write the electron distribution in the atom with 12 electrons.​

Answer 1

Answer:

When we write the configuration we'll put all 12 electrons in orbitals around the nucleus of the Magnesium atom. The p orbital can hold up to six electrons. We'll put six in the 2p orbital and then put the remaining two electrons in the 3s. Therefore the Magnesium electron configuration will be 1s22s22p63s2
