Answer:

2 electrons

E. neon

Explanation:

Metals lose electrons under certain conditions to attain a noble gas electron configuration. Magnesium has 12 electrons and its electron configuration is

1s² 2s² 2p6⁶ 3s²

When magnesium loses 2 electrons, it acquires the electron configuration of neon (10 electrons).

The noble gas electron configuration  attained in the  process of loss of electrons by magnesium is Neon

Generally, In a bid to attain stability either to a duplet state or octet state, Elements,( metals or non metals ) loose or gain electrons.

Magnesium is an element with 12 electrons with electronic configuration,

Magnesium, Mg = 1s2 2s2 2p6 3s2 abd condensed configuration as {Ne} 1s2 and shell notation as 2, 8 , 2 .

Now to attain stability, Magnesium will loose the 2 electrons in its outer most shell to another element, so it becomes stable  with 10 electrons achieving the Neon stable state.
