Ionic & Covalent Bonding SAQ2

Polar Covalent

Ionic compounds tend to have high melting and boiling points, are solids at room temperature, and conduct electricity, whereas covalent compounds often have low melting and boiling points and do not conduct electricity.

The valency of an element determines the number of bonds an atom forms when it reacts, influencing whether an ionic or covalent bond is formed.

<p>σ bonds are formed by the end-on overlap of orbitals, while π bonds are formed by the sideways overlap of p-orbitals.</p> Signup and view all the answers
