What was the difference between thomson's model of the atom and dalton's model of the atom?

Daltons assumed atoms to be the smallest particles and did not acknowledge the presence of electrons and protons. whereas thomson gave the plum pudding model which acknowledged the presence of electrons.

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.
