Cations and Anions: Definitions, Examples, and Differences
网页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.
Cation Definition & Meaning - Merriam-Webster
网页The meaning of CATION is the ion in an electrolyzed solution that migrates to the cathode; broadly : a positively charged ion.
Cations and Anions - Difference Between Anions and Cations
网页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 +).
Cation Definition and Examples - ThoughtCo
网页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.
Ion - Wikipedia
网页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.
Cation vs Anion: Definition, Chart and the Periodic Table
网页2019年8月15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.
The Difference Between a Cation and an Anion - ThoughtCo
网页2024年8月3日 · Cations and anions are both ions. The difference between a cation and an anion is the net electrical charge of the ion. Ions are atoms or molecules which have gained or lost one or more valence electrons, giving the ion a net positive or negative charge.
"Cation" vs. "Anion" – What's The Difference? | Dictionary.com
网页2021年7月27日 · A cation is an ion with positive charge, which means it has more protons (positively-charged particles) than electrons (negatively-charged particles). Cations are formed when an atom loses one or more electrons: the loss of the negatively-charged electron(s) results in an overall positive charge.
7.3: Cations - Chemistry LibreTexts
网页2022年9月20日 · Cations are formed by the loss of one or two electrons from an element. Groups 1 and 2 elements form cations. Cations are named according to the parent element. Cation charges are indicated with a superscript following the chemical symbol.
Cation vs. Anion - Chemistry Coach
网页What is a Cation? Cations are positively (+) charged ions. They form when a metal loses its electron, and they do not have any protons to balance out the charge so it becomes positive in nature (they lose one or more than one). Some examples include calcium (Ca2+), hydrogen (H+), and potassium (K+). What is an Anion?
