Question

A + ion (positive ion, one with extra positive charge)?

Answer 1

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.

Answer 2

If an ion has a positive charge then it has lost an electrons.

Step-by-step explanation:

So you don't "gain" anything when the ion has a positive charge. It loses an electron which means it has more protons than electrons. Thus, the ion has a positive charge. If it "gained" an electron then it would have a negative charge.
