Questions: Write the formula for an example of each of the following compounds: a. nonpolar covalent compound b. polar covalent compound c. ionic compound

Solution Steps

A nonpolar covalent compound is formed when two atoms share electrons equally. This typically occurs between atoms of the same element or between atoms with similar electronegativities. A common example is the diatomic molecule of nitrogen, \( \text{N}_2 \).

A polar covalent compound is formed when two atoms share electrons unequally, resulting in a molecule with a partial positive charge on one end and a partial negative charge on the other. A classic example is water, \( \text{H}_2\text{O} \), where the oxygen atom is more electronegative than the hydrogen atoms.

An ionic compound is formed when one atom donates an electron to another, resulting in a compound composed of positively and negatively charged ions. A common example is sodium chloride, \( \text{NaCl} \).
