How many mL of 1M H2SO4 are required to react with 1 gram of solid containing
50% of Ba(NO3)2, if the reaction is Ba2++ SO4->BaSO4 (Molecular Weight of
Ba(NO3)2= 261.337 g/mol)

They are all full and don't need any more electrons in there outer shell.

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.
