Question

The correct schematic atomic structure and symbol of the element having 4 valence electrons in the M shell is ​

Answer 1

Answer:

silicon

Explanation:

maximum number of electrons in m shell is 18 from formula 2n^2

so atom with 4 valency electrons in 3rd shell is silicon (si)

Answer 2

Answer:

• The element which has four electrons in the M shell or 3rd shell is silicon.

• The symbol of silicon atom is Si.

.       Atomic structure of silicon atom is as follows.

Shells in silicon:

It has 2 electrons in its 1st shell, 8 electrons in the 2nd shell, and 4 electrons in the 3rd shell. As the electrons in the 3rd shell are the outermost electrons, so silicon has 4 valence electrons
