0 07 Ions and predicting charges
Nathan Rycroft・2 minutes read
Atoms can become ions by gaining or losing electrons, resulting in a charge imbalance due to differing numbers of protons and electrons. The periodic table aids in predicting ion charges by grouping elements with similar tendencies to gain or lose electrons, such as alkali metals losing one electron to become ions with a +1 charge.
Insights
- Atoms can become ions through gaining or losing electrons, leading to a charge imbalance based on differing numbers of protons and electrons, resulting in positively or negatively charged ions.
- The periodic table categorizes elements with similar electron tendencies, aiding in predicting ion charges; while alkali metals tend to lose one electron to form a +1 charge, transition metals exhibit variable charges, and polyatomic ions consist of multiple atoms bonded together with an overall charge.

How do atoms become ions?
Atoms become ions by gaining or losing electrons, causing a charge imbalance due to differing numbers of protons and electrons.
What is the difference between cations and anions?
Cations are positively charged ions formed by losing electrons, while anions are negatively charged ions formed by gaining electrons.
How does the periodic table aid in predicting ion charges?
The periodic table groups elements with similar tendencies to gain or lose electrons, helping predict ion charges. For example, alkali metals lose one electron to become ions with a +1 charge.
What distinguishes transition metals from alkali metals and halogens in terms of ion charges?
Transition metals exhibit multiple possible charges, unlike alkali metals and halogens which have predictable charges when forming ions.
What are polyatomic ions composed of?
Polyatomic ions consist of multiple atoms bonded together with an overall charge, such as sulfate with a -2 charge and hydroxide with a -1 charge.

Ion Formation and Charges in Atoms
- Atoms can become ions by gaining or losing electrons, resulting in a charge imbalance due to differing numbers of protons and electrons.
- Protons carry a positive charge, while electrons carry a negative charge, leading to atoms becoming positively or negatively charged ions based on the imbalance of these particles.
- Cations are positively charged ions formed by losing electrons, while anions are negatively charged ions formed by gaining electrons.
