Question

1. complete the table below to compare the different types of covalent bonds.

single bond
double bond
triple bond

electrons shared
three pairs of electrons

example
hydrogen gas

Explanation:

Step1: Recall the definition of covalent bonds

A covalent bond is formed by sharing electrons. A single covalent bond is formed by sharing one pair of electrons. For example, in hydrogen gas (\(H - H\)), each hydrogen atom shares one electron, so one pair of electrons is shared.

Step2: Determine electrons for double bond

A double covalent bond is formed by sharing two pairs of electrons. For example, in oxygen gas (\(O = O\)), each oxygen atom shares two electrons with the other oxygen atom, so two pairs of electrons are shared.

Step3: Find example for triple bond

A triple covalent bond is formed by sharing three pairs of electrons. Nitrogen gas (\(N\equiv N\)) is a common example where each nitrogen atom shares three electrons with the other nitrogen atom.

Answer:

• Electrons shared:
• Single Bond: one pair of electrons
• Double Bond: two pairs of electrons
• Example:
• Double Bond: oxygen gas (\(O_2\))
• Triple Bond: nitrogen gas (\(N_2\))
