The electrons that participate in chemical bonds are located in the "valence shell" or outer energy level of that atom. They are known as the valence electrons, and they are the only part of the atom that participates in a chemical reaction.
The outer electrons of a metal atom that bonds with a nonmetal atom are either transferred to the nonmetal to form an ionic bond or shared with the nonmetal to form one or more covalent bonds.
it is not right to say that " an atom form as many bonds as there are protons?" because an atom of any elemant can form bond to become stable let us take a example of oxygen it have 6 electrons in the outermost shell and to become stable it forms double covalent bond with another oxygen atom or with two hydrogen to form water it means that it forms bond with 2 electrons so in any case of any atom of any element to have 8 electrons it forms the number of bonds of the remaining electrons to form atoms.
Let's use Iron for example (since it is a transition metal, so it can have different number of electrons). Iron (II) has two valence electrons. It combines with chlorine to form FeCl2 Iron (III) has three valence electrons and will combine with chlorine to form FeCl3 The bond formed would still be the same (ionic in both cases), but the energy level would be different.
A carbon atom needs four electrons to have a full outer shell so I guess it can form a maximum of four bonds.
The outer shell electrons of the atom form covalent bonds.
The electrons form bonds with other atom's electrons to form molecules.
Bonds between atoms involve electrons.
none
The number of unpaired electrons in the outermost shell determines the number os covalent bonds an atom can form.
Two oxygen atoms combine to form a molecule by sharing electrons
These are the outer electrons of the atom called valance electrons.
A chlorine atom can form ionic bonds by accepting an electron and covalent bonds by sharing electrons.
ionic bonds form when one atom gains electrons or loses electrons to another atom covalent bonds form when one 2 atoms share electrons in both types of bonding atoms bond to become more stable (to become similar to noble gases by filling their outer most shell)
They are the same you are retarted my god you fruit cake gypsy
The number of electrons in an atom's valence shell determines its valency.
Generally, an ionic bond is formed by the transfer of electrons
covalent bonds
