If metal A is placed in an ionic solution containing metal B ions and no reaction occurs, then metal B is most likely
a catalyst
higher on the activity series
a halogen
not on the activity series

Idon’t know sorry i don’t know the answer i’m s sorry

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.

The correct answer should be "electrons orbit the nucleus in circular motions exactly as shown on the classic bohr model."
