Covalent bonding occurs when atoms share electrons, with non-metals being the only participants.
There are two types of covalent bonding: simple covalent, which involves small molecules like CH4, H2O, CO2, and giant covalent, which involves thousands of atoms joined together.
Ionic bonding involves the transfer of electrons, with both metals and non-metals participating.
Examples of metallic substances include magnesium, calcium, aluminium, copper, sodium, and iron.
Metals and non-metals form ionic bonds.
The attraction between the positive ions and the electrons in a metallic bond is strong electrostatic attraction.
Metallic bonding occurs only within metals, where metal atoms lose electrons out of their outer shell, forming positive ions, and the electrons they lose become delocalized, floating around in a sea of delocalized electrons.
Sodium chloride is the only compound that has both a metal and a non-metal present, making it ionic.
An ionic bond is a strong electrostatic attraction between positive ions and negative ions, often seen in giant ionic lattices like calcium chloride, magnesium oxide, and aluminium bromide.
Metallic bonding occurs only within metals, with non-metals never being involved.
Covalent bonding happens only in non-metals, with metals never being involved.
Covalent bonding occurs when two non-metal atoms or more than two share a pair of electrons.
Covalent bonding is a shared pair of electrons that join two atoms together, making it a very strong bond.
Covalent bonding can occur between elements that are non-metals, either two atoms of the same element or different elements.
