What is a covalent bond An ionic bond?

Answer 1

A covalent bond is a chemical bond between two nonmetals (two metals cannot covalently bond) in which electrons are shared, while an ionic bond is a chemical bond between a metal and a non metal due to the attraction between oppositely charged ions.

Answer 2

A Covalent bond arises as a result of the sharing of two or more valence electrons usually by non metallic element so that both can attain the octet or hexase structure of the group zero elements while ionic bond occurs when metals transfer electrons to non-metals in a chemical reaction so that both can attain a stable state.by Augustine Okoche

Answer 3

A covalent bond is a bond between two nonmetals, where the electrons are essentially shared.

For example water is H2O.

Oxygen needs two more electrons to have a full valence (outer shell) and each hydrogen needs one electron, so they share electrons to form the stable compound water.

An ionic bond is a bond between a metal and a nonmetal, where there is an exchange of electrons. Since one atom is giving up electrons it has an overall positive charge, the other atom then is gaining electrons, leaving it with a negative charge. Since opposites charges attract, the compound is stable and stays together

For example salt is NaCl.

Sodium needs to get rid of the extra electron so that it has a stable valance shell, while chlorine needs to gain another electron to have a full valance shell. So sodium gives its extra electron to chlorine, and now they both are stable.

Answer 4

Ionic bond is a force of attraction between positive and negative ions. A covalent bond occurs when atoms share electrons, in which there is no formation of ions.
