Metals to non-metals across a periodFree2:55Heddy Score 3 of 7, below the standard
What you need to know
- Metals are on the left of the zigzag staircase line and non-metals are on the right; hydrogen is the exception.
- Metals are shiny, malleable, ductile and good conductors of heat and electricity; all except mercury are solid at room temperature.
- Non-metals are generally dull, brittle insulators and are often gases at room temperature.
- Metalloids sit along the staircase, have some properties of both, and are used as semiconductors, e.g. silicon in computer chips.
