Ionic vs Covalent

[Donavin Collins 1F]

How can you tell if a bond is ionic or covalent?

[AronCainBayot2K]

You can tell if a bond is ionic or covalent based on the atoms present. Ionic bonds are bonds between a metal and nonmetal whereas covalent bonds are bonds between two nonmetals. Knowing this, you can determine whether a bond is ionic or covalent.

The difference is their electronegativity. If the electronegativity between the two atoms is more than 2.5, the bond is ionic. If the electronegativity between the two atoms is less than 1.5, the bond is covalent. Between 1.5 and 2.5, the bond has ionic and covalent components.

[Yiyang Jen Wang 4G]

ionic bond is usually between a metal and a nonmetal. Elements in ionic bonds donate and accept electrons (become ions) while in covalent bonds they share electrons.

[Marykate Abad 3L]

Ionic bonds are between a metal and nonmetal. Covalent bonds are between two nonmetals.

[Kevin Liu 1J]

Ionic bonds are where electrons are fully transferred from one atom to another, while covalent bonds are strictly shared between atoms.

[derinceltik1K]

ionic bonds are between a metal and a nonmetal. They occur through electrostatic attraction of the cation metal and anion nonmetal.
Covalent bonds are between nonmetal atoms. It is through electron sharing.

EN greater than 2.5 = ionic
EN less than 1.5 = covalent
in the middle is a blend of both

[Aarushi Solanki 4F]

An electronegativity difference of more than 2.5 indicates that the bond is ionic. An electronegativity difference less than 1.5 indicates that the bond is covalent. An electronegativity difference between 1.5 and 2.5 indicates that the bond has ionic and covalent character.

[Cynthia Rodas 4H]

Ionic bonds are usually between a metal and a nonmetal. Covalent bonds, on the otherhand, are typically between two nonmetals. Another way to differentiate is by looking at the electronegativity difference. If the electronegativity difference is greater than 2, then it is an ionic bond. If the electronegativity difference is less than 1.5, then it is a covalent bond.

A main distinction between covalent and ionic bonds are that ionic bonds are between a metal and nonmetal. Covalent bonds are between two nonmetals. Additionally, the EN difference for ionic bonds are greater than 2.5 and lower than 1.5 for covalent bonds.

The difference between ionic and covalent bonds are the type of element involved in the reaction. Ionic bonds are between a metal and a nonmetal while covalent bonds are between two non-metals.

How can you tell if a bond is ionic or covalent?

ionic bonds are generally between metals and nonmetals and covalent bonds are between nonmetals. However, the bond type is ultimately determined by the electronegativity difference between the two atoms.

[Marykate Abad 3L]

An ionic bond is between a metal and nonmetal while a covalent bond is between two nonmetals.

[Sean Cheah 1E]

Additionally, an electronegativity difference less than 0.5 generally represents a nonpolar covalent bond while an electronegativity difference between 0.5 and around 1.5 represents a polar covalent bond.
