The last column of the periodic table contains the noble gases, elements that do not easily form chemical bonds. why don’t these gases tend to form chemical bonds?

I think this is because they already have 8 valence electrons, so forming chemical bonds wouldn't really be easy, as it would be 0 valence.

(that's what i put in my lab lol)

specific gravity is the density of a substance divided by the density of water. since (at standard temperature and pressure) water has a density of 1 gram/cm3, and since all of the units cancel, specific gravity is usually very close to the same value as density

so "c" is the answer

plz give brainliest
