- Cations and Anions: Definitions, Examples, and Differences
The chemical formula of a compound is always written with the cation first, followed by the anion For example, Na is the cation and Cl is the anion in NaCl (table salt)
- 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
- Cation vs Anion: Definition, Chart and the Periodic Table
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
- Cations and Anions - Ions | ChemTalk
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
- The Difference Between a Cation and an Anion - ThoughtCo
When writing the formula of a compound, the cation is listed before the anion For example, in NaCl, the sodium atom acts as the cation, while the chlorine atom acts as the anion
- 1. 13: Ions: Atoms That Have Lost or Gained Electrons
The cation produced in this way, Na +, is called the sodium ion to distinguish it from a neutral sodium atom The outermost shell of the sodium ion now has eight electrons in it, and the octet rule has been satisfied Figure 1 13 1 is a graphical depiction of this process Figure 1 13 1: The Formation of a Sodium Ion
- 7. 3: Cations - Chemistry LibreTexts
Summary 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 pare nt element Cation charges are indicated with a superscript following the chemical symbol
- Anion vs Cation - Difference and Comparison | Diffen
A cation is an atom or a molecule which is positively charged, i e has more number of protons than electrons Anion originated from the Greek word ano, meaning ‘up’ The word cation originated from its Greek counterpart kata, which means ‘down’
