All electrons are the same, they only differ in spin.
The electrons in the outermost energy shell are generally those involved in the formation of chemical bonds particularly when the innermost shells have the same electronic configuration as a noble gas.
There are many exceptions . For instance in copper(II) compounds both the outer 5s electron and a 4d electron are involved. The ionisation potential of each successive electron can give a guide as to whether it takes part in bonding or is too tightly held.
valence electrons
covalent bond
covalent
Covalent bonding. It can be two types - polar covalent or nonpolar covalent. In polar covalent bonding, atoms do not share electrons equally. In nonpolar covalent bonding, atoms share electrons equally.
in H-O-H, dihydrogenoxide they are all used for bonding
The valence electrons are involved in chemical bonding.
All of the valence electrons are used for bonding.
These are the valence electrons.
ionic bonding
Typically, the valence electrons, the electrons in the outermost shell, of an atom are used in bonding.
covalent bonding is used to share electrons
It's covalent bonding ((:

valence electrons
Ionic
Metal or atomic bonding: electrons are not shared but pooled together in the "conductivity sea" of electrons
Covalent bonding occurs when atoms share two or more electrons. Electrons are shared in pairs.
