Final answer:
A positive ion with an extra positive charge is called a cation. A cation forms when a neutral atom loses one or more electrons, resulting in more protons than electrons. An example is the sodium ion (Na+), which has lost one electron and has a 1+ charge.
Step-by-step explanation:
A positive ion with an extra positive charge is called a cation.
A cation forms when a neutral atom loses one or more electrons, resulting in more protons than electrons. This creates a net positive charge.
An example of a cation is the sodium ion (Na+), which has lost one electron and therefore has a 1+ charge.
