Guida verificata passo dopo passo1
Understand the definition of a cation: A cation is an ion that has a positive charge.
Recall how ions form: Atoms form ions by either losing or gaining electrons.
Remember that electrons carry a negative charge, so losing electrons results in a net positive charge.
Therefore, a cation is formed when an atom loses one or more electrons, resulting in a positive ion.
Conclude that the correct completion of the sentence is: 'A cation is an element that loses one or more electrons to form positive ions.'
