Question

What happens to an atom when it becomes a positively charged ion?

Answer

When an atom becomes a positively charged ion, it loses one or more electrons. This loss results in more protons than electrons, giving the ion a net positive charge.

Explanation

This question assesses the application of knowledge regarding ion formation. The answer effectively describes the process of electron loss and its impact on the atom's charge, demonstrating an understanding of atomic behavior.

Common mistake

Neutral Atoms vs Charged Ions

Students often confuse neutral atoms with charged ions, thinking they are the same because both contain protons and electrons.

To fix this, remember that a neutral atom has equal numbers of protons and electrons, resulting in no overall charge, while a charged ion has an unequal number of protons and electrons, leading to a positive or negative charge.
