Answer:
Explanation:
Properties of metals:
1. They have a lustre ( shine )
2. They have a silvery-grey or golden-yellow colour.
3. They conduct heat and electricity.
4. They are ductile ( can be drawn into wires ) .
5.They are malleable ( can be hammered into thin sheets ).
6. They are sonorous ( make a ringing sound when hit ).
Properties of non-metals:
1. They display a variety of colours.
2. They are poor conductors of heat and electricity.
3. They are not lustrous, ductile or malleable.

Answer:
Two electrons each!
Explanation:
The question pretty much requires us to find the oxidation number of Zinc in the compound.
Zn3P2
Following oxidation number rules;
O.N of Zn3P2 = 0
.Since phosphorus has valence of 5, it needs three more electrons to achieve its octet state. Hence;
Oxidation number of P = -3
Let oxidation number of Zn = x
We have;
3x + 2 (-3) = 0
3x + (-6) = 0
3x = 6
x = 6/3 = 2
This means each zn electrons lost 2 electrons.
Chlorine has less valence electrons than bromine, and, therefore, needs to bond with another atom to become more stable .
