If a sample of neon (ne) contains 1.01×10^22 atoms, what is it's mass

no of atoms=mass in grams×6.02×10²³/atomic mass
mass in grams= no of atoms of neon×atomic mass/ 6.02×10²³
mass in grams= 1.01×10²²×20/6.02×10²³
mass in grams=2.02×10²³/6.02×10²³
mass in grams=0.3355 grams

Non metal is an element or substance that is not a metal metal is a solid material that is typically hard, shiny, malleable, fusible, and ductile, with good electrical and thermal conductivitymetalloid is an element (e.g., germanium or silicon) whose properties are intermediate between those of metals and solid nonmetals. they are electrical semiconductors.
