To draw a Lewis structure for a covalent compound, begin by calculating A, the available electrons, and N, the needed electrons.
what is N for silicon tetrachloride, SiCl4

( I know that the available amount is 32 but I can't figure out the needed amount)

no, the red giant is the hottest with 2.00.000.000 degrees celsius. while the white dwarf only 25,000 degrees celsius.

i think   the answer is c hope i'm right

if the temperature drops and becomes cool

then the atmosphere can be freezing as the water vapor in the air is at maximum (100%) and can be severely cold

also can be snowing lightly as the moisture in the air will start to solidify

and btw this is not chemistry but
