What's an Ion? | Summary and Q&A

TL;DR

Ions are atoms or groups of atoms that have an electrical charge, either positive or negative.

Key Insights

• 💁 Ions are formed when there is an imbalance between the number of protons and electrons in an atom.
• 💁 Cations are ions with a positive charge, formed when atoms lose electrons.
• 💁 Anions are ions with a negative charge, formed when atoms gain electrons.
• 😚 Sodium (Na) can become a cation by losing an electron.
• 👌 Oxygen (O) can become an anion by gaining electrons.
• 🍹 Ions can be represented using symbols, such as Na+ for sodium cation and O2- for oxygen anion.
• 😐 Neutrons do not have an electrical charge and are neutral.

Questions & Answers

Q: What is an ion?

An ion is an atom or a group of atoms that have an electrical charge due to an imbalance of protons and electrons.

Q: How do atoms become ions?

Atoms can become ions by gaining or losing electrons. When an atom loses electrons, it becomes a positively charged ion (cation), while gaining electrons results in a negatively charged ion (anion).

Q: What is the difference between a cation and an anion?

A cation is a positively charged ion, formed when an atom loses electrons. An anion, on the other hand, is a negatively charged ion, formed when an atom gains electrons.

Q: How does sodium (Na) become a cation?

Sodium can become a cation by losing an electron. This imbalance in the number of protons and electrons results in a positive charge.

Summary & Key Takeaways

• Ions are atoms or groups of atoms that have an electrical charge due to an imbalance of protons and electrons.

• Atoms can become ions by gaining or losing electrons, resulting in either a positive or negative charge.

• Sodium (Na) can become a positive ion (cation) by losing an electron, while oxygen (O) can become a negative ion (anion) by gaining electrons.
