The Pcl6 has 48 bonded electrons and 18 lone pairs.
The Lewis structure of Pcl6 is as follows: -
Phosphorous is bonded with 6 chlorine atoms with 18 lone pairs.
Lewis structures, also known as Lewis dot formulas, Lewis dot structures, electron dot structures, or Lewis electron dot structures (LEDS), are diagrams that show the bonding between atoms of a molecule, as well as the lone pairs of electrons that may exist in the molecule. [1][2][3] A Lewis structure can be drawn for any covalently bonded molecule, as well as coordination compounds.
In Lewis structure, atoms are bonded with single bonds. If total number of electrons are 't' and number of bonds are 'n', then t-2n number of electrons are to be placed. Once the central atom is placed, they need to complete the octet rule.

The answer is D "Volatility"
have a great day!!!
True
Explanation:
The position of sodium on the periodic table makes the element a solid at room temperature is very correct.
- Sodium is an elements with 11 electrons in its shell.
- It is located in group 1 on the periodic table because it contains an outer valence electron.
- In a free state Na metal, the atoms exhibit metallic bonding.
- Metallic bonding is responsible for the solid nature of this alkali metal at room temperature.
- It is highly reactive because it has just one valence electron.
- Metals are usually found left of the periodic table.
