Which of the following groups of elements are all malleable, conduct electricity and are lustrous?

f: CI, He, Ne
G : Cu, Na, Mg
H : Mg, Ar, B
J : Si, As, Se

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

that tool would be a compass

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
