give the bonds existing in these different compounds and molecules...

1. Fe2O3
2.F2
3. CaO
4. Al2)3
5. HCl

1. Iron oxide or ferric oxide has three oxygen atoms and two iron atoms. The bond formed between iron and oxygen is due to the difference in electronegativity between the two atoms. ... Since iron is metal and oxygen is non-metal therefore the bonding between oxygen and iron is ionic.

2. Covalent.

In F2 the bonding is pure covalent, with the bonding electrons shared equally between the two fluorine atoms.

3. Ionic bond

. CaO is an ionic bond. Definition: Two-element compounds are usually ionic when one element is a metal and the other is a non-metal.

4. Ionic bond. Technically this is polar covalent bond, as the difference in electronegativity is <= 2, but it's also very close to being an ionic bond (defined as ΔEN > 2).

5. Covalent. HCl, also known as hydrochloric acid, has a covalent bond. The hydrogen (H) atom shares an electron with the chlorine (Cl) to form the bond.

Answer:

1. Ionic Bond

2. Covalent Bond

3. Ionic Bond

4. Ionic Bond

5.Covalent Bond

Explanation:

A covalent bond in chemistry is a chemical link between two atoms or ions in which the electron pairs are shared between them. A covalent bond may also be termed a molecular bond. Covalent bonds form between two nonmetal atoms with identical or relatively close electronegativity values.

Ionic bonding is a type of chemical bonding that involves the electrostatic attraction between oppositely charged ions, or between two atoms with sharply different electronegativities, and is the primary interaction occurring in ionic compounds.
