Question

what particle is made in a covalent bond ?​

Answer 1

Answer:

A covalent bond is a chemical bond that involves the sharing of electron pairs between atoms. Molecules and polyatomic ions are formed by covalent bonds.

Explanation:

Answer 2

A monoatomic molecule(N₂) or a polyatomic compound(H₂O) is made in a covalent bond.

• This type of bond forms when two similar or very low electronegative different atoms, share equally the outermost or valence electrons from their furthest orbits to attain a stable configuration.
• Essentially, all non-metallic gaseous elements exist naturally in the form of diatomic gases like oxygen(O₂), Nitrogen(N₂), etc.
• This sort of bond generally exist between elements occuring while moving horizontally right through the periodic table as the elements are more electronegative or non-metals. They have high ionization energy, i.e., it takes a lot of energy to remove their valence or outermost electrons as they are strongly attached to the nucleus unlike metals.
• These bonds are much weaker than ionic bonds as they do not completely transfer their electrons to each other, rather share them to attain stability.
• Example:- Oxygen (O₂) element has 8 electrons. Thus, it has a configuration of 2,6 or 1s²,2s²,2p⁴. As following the octet rule, the elements must have 8 electrons to attain stability thus it shares their two electrons with another oxygen atom to form diatomic oxygen.
