Which statement describes the general trends in electronegativity and metallic properties as the elements in period 2 are considered in increasing atomic number?
(1) both electronegativity and metallic properties decrease.
(2) both electronegativity and metallic properties increase.
(3) electronegativity decreases and metallic properties increase.
(4) electronegativity increases and metallic properties decrease.

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
