WebHelium is a chemical element with atomic number 2 which means there are 2 protons in its nucleus. Total number of protons in the nucleus is called the atomic number of the atom and is given the symbol Z. The total electrical charge of the nucleus is therefore +Ze, where e (elementary charge) equals to 1,602 x 10-19 coulombs.
WebSep 16, 2024 · Nonmetals. Elements that tend to gain electrons to form anions during chemical reactions are called non-metals. These are electronegative elements with high ionization energies. They are non-lustrous, brittle and poor conductors of heat and electricity (except graphite). Non-metals can be gases, liquids or solids. In words, the density (ρ) of a substance is the total mass (m) of that substance divided by the total volume (V) occupied by that substance.
