List the following elements from least number of valence electrons to most number of valence electrons. Bromine, Carbon, Xenon, Lithium, Magnesium

Explanation:

one valence electron

Lithium has a single electron in the second principal energy level and so we say that lithium has one valence electron. Beryllium has two valence electrons.

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

it’s previous models   because when i picked that son of a gun’s answer it was wrong look for previous models because they might make it a different letter
