Metals
1 they allow electricity and heat to pass through them easily
2 they are all solids in room temperatures exept for Mercury , and most of them have high melting points.
3 nost of them can be hammed into different shapes
non metals
1 they are poor conductorsof electriity and heat
2 they usually have low melting points
3 when solid non-metals are hammed, they break up-they are brittle.
Metalloids have properties that are in between those of metals and non-metals, making their classification difficult. They exhibit both metallic and non-metallic properties such as conductivity and brittleness, which can vary depending on the specific element and conditions. This dual nature makes it challenging to categorize them definitively as either metals or non-metals.
all are non metals
metals on left, non-metals on right, some others in middle.
Atoms of non-metals usually gain or share electrons when they react with other atoms.
Non-metals, metals and semiconductors. Metals are on the left, non-metals on the right, and semiconductors sitting near the staircase line that divides the metals and non-metals.
The oxidation number of non-metals can vary depending on the element and the compound it is in. Generally, non-metals tend to have negative oxidation numbers when they form compounds with metals, but they can also have positive oxidation numbers when they form compounds with other non-metals.

Non metals
all are non metals
My opinion would be metal. Since non metals are brittle and dull, I disagree with the non-metals.
They are in between the metals and non metals
The most reactive non metals are Halogens which may combine most of the metals as well as non metals.
Non-metals, they are all gases.
Non-metals
In general, non metals are more electronegative
