Metals and Non-Metals Flashcards
Most Elements are Metals:
Metals are elements which can form positive ions when they react.
They’re towards the bottom and to the left of the periodic table
Most elements in the periodic table are metals
Non-metals are at the far right and top of the periodic table
Non-metals don’t generally form positive ions when they react
Do Metals and Non-metals have different physical Properties?
Yes
All metals have metallic bonding which causes them to have similar basic physical properties:
They’re strong (hard to break), but can be bent or hammered into different shapes (malleable).
They’re great at conducting heat and electricity.
They have high boiling and melting points.
As Non-metals don’t have metallic bonding, they don’t tend to exhibit the same properties as metals. They tend to be dull looking, more brittle, aren’t always solids at room temperature, don’t generally conduct electricity and often have a lower density.
