If an electron is in the n=1 shell, what is the electrons scaled energy in electronvolts

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 would be d. henry moseley

hope this !
