The Difference Between Metals and Non-metals

# data[].attributes.body
Metals is an element that conducts electricity and is malleable and ductile.
Non-metals is an element that does not conduct electricity well and is neither malleable nor ductile.
There are many other differences between metal and non-metals, for example
 metals are good conductor of heat, on the other hand non-metals are poor thermal conductors. etc

Now as you know, 8 groups exists in the periodic table but if I try to explain all of them this will become a Wikipedia page so I will stick with the important ones.

-Group I
The Groups I metals are mostly called alkali metals, which means they are soft and relatively low densities and low melting points.
These metals are highly reactive and they reactive with oxygen and water which means they have to be stored in oil to prevent exposure.

-Group VII
The halogens are the most reactive  non-metals in group VII. Chlorine, Bromine, Iodine are the most common examples of halogens.
As you know halogens are very reactive and will aggressively react with both metals and non-metals, for example, Chlorine dissolves in water to give an acidic solution called chlorine water-
Cl2 + H20 - HCl + HClO
Chlorine water acts as an oxidising agent.

The noble gases are very stable because of the electron arrangements of the atom, this means that they do not react with readily with other atom. When atoms of other element bond or react chemically, they are trying to achieve that stable arrangements found in noble gases.
Noble gases can be used in many ways like, Argon is used to gill light bulbs, neon is used in lights to give it that fluorescent colour.

Chemical bonding is a bonding which involves the outer electrons of each atom, now there is 2 type of bonding, bonding in element and compounds

# data[].attributes.body
2 non-metals are held together by covalent bonding, which means in simple molecules or giant molecular lattices. They can also be held by ionic bonding which results in giant ionic lattices

Covalent Compounds-
In covalent compounds, bonds are again made from sharing electrons between atoms, then in simple molecules, the atoms combine to achieve a more stable arrangement of electrons.

# data[].attributes.body
The transfer of electrons result in the formation of positive and negative ions, which means oppositely charged ions are then attracted to each other by electro static force.
In a whole giant ionic structure is held together by the electrostatic forces of attraction that occur between particles of opposite charge.

# data[].attributes.body
So as we know metallic element are held together by metallic bonding which results in metallic lattices and non-metal elements are held together by covalent bonding.

Metallic Bonding-
Metal atoms more easily lose electrons then gain them, so they become positive ions.

Ions-
A charged particle made from an atom by the loss or gain electron.

Non-metallic Bonding-
Non-metal bond is formed by the sharing of a pair of electrons between two atoms, each atom contributes one electrons to each bond.
