Covalent bonding:
Chemical bonds are formed by the sharing of electrons.
Ionic bonding:
Chemical bonds are formed when a metallic object and a non-metallic object share electrons.
Metallic bonding:
In metallic bonding, electrons are not fixed to an atom, but in a metal, they are delocalized.
Groups in the periodic table
10/6/25
The left side of the periodic table is metallic, and the right side is non-metallic.

Electrons have different levels of orbitals, and the level of orbitals depends on the amount of energy the electron carries. Specific electrons emmit sepcific color depending on the height of the electron orbits. Electron orbitals represent the quantum perspective of orbits, showing the area where an electron is likely to be present. Atoms do have infinite number of orbits, but it can never reach it because the electron often emmits the energy to get more stable and go down the orbit, so if its in the 3rd orbit, it jumps down the 1st orbit by emmiting energy, the energy depends on the height of the orbit, if energy is higher you will get a wave with higher energy.
