Magnesium and oxygen combine to form magnesium oxide, Mgo. In a particular experiment, 15.5 g magnesium reacted with 18.2 liters of oxygen (at STP)

C) electrons encircling a nucleus with neutrons and protons

Perimeter? wheres the answers

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."
