Multiple Choice

Which statement correctly describes how the binary ionic compound KBr is named?

The name is formed by writing the name of the cation followed by the name of the anion without changing its ending, resulting in potassium bromine.

The name is formed by using prefixes to indicate the number of each atom, resulting in monopotassium monobromide.

The name is formed by writing the name of the cation (potassium) followed by the name of the anion with its ending changed to 'ide' (bromide), resulting in potassium bromide.

The name is formed by writing the name of the anion (bromine) first, followed by the cation (potassium), resulting in bromine potassium.

Verified step by step guidance

Identify the ions involved in the compound KBr: potassium (K) is the cation and bromine (Br) is the anion.

Recall the naming convention for binary ionic compounds: the cation name is written first, using the element's name as is.

For the anion, change the ending of the element's name to '-ide' to indicate it is an anion in a binary compound.

Combine the cation name and the modified anion name to form the compound name, resulting in 'potassium bromide'.

Note that prefixes are not used in naming ionic compounds because the ratio of ions is determined by charge balance, and the anion is named after the element with the '-ide' suffix.
