Bonds - Chapter 6

An ionic bond is a type of chemical bond formed through the electrostatic attraction between oppositely charged ions, typically formed when one atom donates an electron to another.

A covalent bond is a type of chemical bond where two atoms share one or more pairs of electrons.

The formula for magnesium hydroxide is Mg(OH)₂.

An ionic bond is formed between magnesium (Mg) and oxygen (O).

SO₂ has a covalent bond.

The ionic compound formed between barium (Ba) and phosphorus (P) is Ba₃P₂.

The charge of a barium ion (Ba²⁺) is +2.

The charge of a phosphorus ion (P³⁻) in ionic compounds is -3.

Ionic bonds involve the transfer of electrons from one atom to another, while covalent bonds involve the sharing of electrons between atoms.

The octet rule states that atoms tend to bond in such a way that they each have eight electrons in their valence shell, achieving a stable electron configuration.
