Magnesium with atomic number 12 attains the stable electronic configuration of the nearest noble gas :
Open in App
Solution
The correct option is A Neon
Magnesium with atomic number 12 and electronic configuration 2(K), 8(L),
2(M). Therefore, it has two electrons in its valence shell. It donates
two electrons from its M shell to attain the stable electronic
configuration of the nearest noble gas neon. Thus, the magnesium ion
has two positive charges.
