Because they need 8 valecne electorns, and some don't so they share or transfer. :)
covalent bonds are formed when electrons are shared between atoms.
Carbon atoms tend to form covalent bonds with other carbon atoms and with atoms such as hydrogen, oxygen, nitrogen, and halogens. Carbon can also form double and triple bonds with other carbon atoms or heteroatoms, giving rise to a wide variety of organic compounds.
Covalent bonds are formed when atoms share electrons
A compound is formed from atoms. Covalent bond is weaker.
Butane forms covalent bonds. It is a hydrocarbon composed of carbon and hydrogen atoms which share electrons to form covalent bonds.
Yes, alkanes contain covalent bonds. Covalent bonds are formed by the sharing of electrons between atoms in a molecule, and in alkanes, carbon atoms form covalent bonds with hydrogen atoms to create a chain-like structure.
Molecules
Only nonmetals can form covalent bonds. Mainly because in a covalent bond the atoms are sharing electrons, as in an ionic bond the two atoms are taking electrons.
No, silver atoms typically do not form covalent bonds with other atoms. Silver is a transition metal and tends to lose electrons to form positively charged ions rather than share electrons in a covalent bond.
Non-metal atoms typically form covalent bonds by sharing electrons to achieve a full outer electron shell and become more stable.
Covalent bonds form between non-metal molecules. Covalent bonds come in 2 kinds: polar and nonpolar. If the two atoms bonding have an electronegativity difference of less than .5, then the bond is usually considered nonpolar covalent. If the difference is greater than .5 but less than 2 the bond is usually considered polar covalent.
