Relationships are difficult because people choose to walk away instead of having to try harder.

A) the enthralling of formation for pure element in its standard state is always positivehope this : )

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.
