Based on the article "will the real atomic model stand up" describe one major change that occurred in the development of the modern atomic model.

Ithink the answer is a or d.

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.

Solubility would be your answer.
