The number of electrons in the outermost energy level (valence electrons) and their energy levels determine how an atom will bond to another atom. Atoms tend to bond in a way that allows them to achieve a stable electron configuration, often by either gaining, losing, or sharing electrons to fill their outer energy level.

Noble gases have a full valence shell with 8 electrons, except for helium which has 2. This makes them very stable and unreactive.
Zinc has 2 valence electrons.
Aluminum has 3 valence electrons.
Ionic bonds do not have valence electrons; rather, they form between atoms by electron transfer where one atom gives up electrons (cations) and the other gains electrons (anions). The resulting ions are held together by electrostatic forces, not by sharing electrons as in covalent bonds.
it has 4 valence electrons
Br2 has a total of 14 valence electrons, with each Br atom contributing 7 valence electrons. This allows them to form a covalent bond by sharing electrons with each other.
In a triple bond between two atoms, a total of six valence electrons take part. Two electrons come from each atom to form the sigma bond, and the remaining four electrons form two pi bonds.
Cations have fewer valence electrons than the number they started with. The number of valence electrons that cations have after bonding is dependent on the element they originate from.
Nitrogen can have either 3 or 5 valence electrons. The number changes because the 2 electrons from the 2s shell can bond as well as the 3 electrons in the outer 2p shell.

Silicone has 4 valence electros so it would need 4 hydrogen atoms to give itself an octet of valence electrons.

the group in which an element falls = # of valence electrons eg Na gp 1 = 1 valence e Ca, gp 2 = 2 valence e and so on....... the number of covalent bond an element makes really depends on which other element it bonds with but note this a covalent bond consist of 2 electrons so how many covalent bonds formed will depend on how many electrons an atom has in its valence shell - covalent bond are mostly between non metals and involves electron sharing carbon forms the longest chain of covalent bonds with itself...

Indium has 3 valence electrons.
