Answer 2

Answer:

Electronic configuration-

An element's electron configuration describes the distribution of electrons in its atomic orbitals. Atomic electron configurations are represented by a standard notation in which all electron-containing atomic subshells (with the number of electrons they hold written in superscript) are ordered. The electron configuration of sodium, for example, is 2,8,1.

Explanation:

Magnesium is the element with the atomic number 12.

K-shell

• The maximum holding capacity of electrons is =2
• Hence the K-shell will hold = 2 electrons(Mg).

L-shell

• The maximum holding capacity of electrons is =8
• Hence the L-shell will hold = 8 electrons(Mg),

M-shell

• The maximum holding capacity of electrons is = 18
• Hence, the number of electrons left are 2 the M-shell will hold = 2 electrons(Mg).

Magnesium's electron configuration

The initial two electrons will enter the 1s orbital. Because the first orbital can only hold two electrons, the remaining two electrons for magnesium are placed in the 2s orbital. Because the p orbital can only hold six electrons, the next six electrons will be placed in the 2p orbital. Then, in the 3s, place the remaining two electrons.

As a result, the electron distribution of Magnesium will be 2, 8, 2.
