Cations and Anions: Definitions, Examples, and Differences
2020年3月3日 · Cations are ions that have a positive charge. The word “cation” comes from the Greek word ánō, which means “up.” Examples of cations include: Silver: Ag + Hydronium: H 3 O + Ammonium: NH 4 + Because an electron is removed to form a cation, the cation of an atom can be smaller than the neutral atom.
Ion - Wikipedia
A cation is something that moves down (Greek: κάτω, kato, meaning "down") and an anion is something that moves up (Greek: ἄνω, ano, meaning "up"). They are so called because ions move toward the electrode of opposite charge.
Cations and Anions - Difference Between Anions and Cations
Cations are positively charged ions. They are formed when a metal loses its electrons. They lose one or more than one electron. It has fewer electrons than protons. Therefore, they possess a net positive charge. Some examples of cations are Calcium (Ca 2+), Potassium (K +), hydrogen (H +). What are anions? Anions are negatively charged ions.
Cation vs Anion: Definition, Chart and the Periodic Table
2024年1月24日 · What is a cation? A cation has more protons than electrons, consequently giving it a net positive charge. For a cation to form, one or more electrons must be lost, typically pulled away by atoms with a stronger affinity for them.
CATION Definition & Meaning - Merriam-Webster
The meaning of CATION is the ion in an electrolyzed solution that migrates to the cathode; broadly : a positively charged ion.
The Difference Between a Cation and an Anion - ThoughtCo
2024年8月3日 · Cations and anions are both ions, but they differ based on their net electrical charge; cations are positive, while anions are negative.
Cation Definition and Examples - ThoughtCo
2019年5月5日 · A cation is an ionic species with a positive charge. The word "cation" comes from the Greek word "kato," which means "down." A cation has more protons than electrons, giving it a net positive charge.
Cations and Anions | Ions - ChemTalk
What is a cation? A cation is an ion that has lost one or more electrons, giving a net positive charge. Because one or more electrons are removed to form a cation, the cation of an atom is smaller than the neutral atom. Examples of cations include the following: Calcium: Ca 2+ Silver: Ag + Aluminum: Al 3+ Hydronium ion: H 3 O + Ammonium: ion NH 4 +
7.3: Cations - Chemistry LibreTexts
2025年3月21日 · Some elements lose one or more electrons in forming ions. These ions are known as " cations " because they are positively charged and migrate toward the negative electrode (cathode) in an electrical field.
