metals and non metals

What are metals and non metals where are they found

Metals are elements which can form positive ions when they react. Most metals are found further down the periodic table and to the left-hand side.

Nonmetals are elements which don’t form positive ions when they react. They either form negative ions or don’t form ions found right hand side

Why do metals become more reactive towards the bottom of the table

Because elements far down have lots of shells so the outer shell is very far from the nucleus. The positive nucleus holds negative electrons in place so if the electrons are very far away the nucleus can’t hold onto them so strongly so they’ll be able to lose them more easily and form a positive ion . Which makes them more reactive ( able to lose electrons more easily during reactions)

Why is it hard for non metals to form positive ions

Nonmetals are found on the right hand side of the periodic table where they have lots of electrons to remove to get a full outer shell. That requires a lot of energy so will not happen. Done metals are also found towards the top where the outer electrons are very close to the nucleus so you are strong attraction. It’s a lot more easier to gain an electron to form a full outer shell

Why is it easy for metals to form positive ions

Metals to the left of the periodic table don’t have many electrons to remove from the outer shell metals towards the bottom of the periodic table of electrons which are a long way From the nucleus so of weaker attraction both of these affect mean that not much energy is needed to remove the electrons from the outer shell

What are the physical properties of metals

-All metals have metallic bonding - strong

-metals are malleable ( can be bent/shaped without breaking)

-great conductors of heat and electricity

-high melting and boiling points

-sonorous -(create ringing sounds)

What are physical properties of non metals?

-dull

-brittle

-low boiling and melting points

-poor conductors of electricity

-low densities than metals
