Question

Are covalent bonds formed my elemnts having same valency

Answer 1

The carbon's four valence electrons can be shared by other atoms (that haveelectrons to share), thus forming what we call covalent bonds (shared electronsbonds). ... Silicon (Si), another element in group 14 of the periodic table, also has four valence electrons and can make large molecules called silicones.

Answer 2

CHEMICAL BONDING:

✷A chemical bond is a lasting attraction between atoms, ions or molecules that enables the formation of chemical compounds.

TYPES OF CHEMICAL BONDING:

✷There are three main types of bonds: ionic, covalent and metallic.

✷A covalent bond is a form of chemical bonding which is characterized by the sharing of electrons between atoms. Covalent bonds are mainly formed due to the tendency of the elements to attain a completely filled outer shell, that is, attain noble gas configuration and become stable.✔
