Anions

from class:

General Biology I

Definition

Anions are negatively charged ions formed when an atom gains one or more electrons. They play crucial roles in various biological and chemical processes.

congrats on reading the definition of anions. now let's actually learn it.

ok, let's learn stuff

5 Must Know Facts For Your Next Test

  1. Anions are typically larger than their parent atoms due to the addition of one or more electrons.
  2. Common examples of anions include chloride (Cl-), sulfate (SO4^2-), and nitrate (NO3-).
  3. Anions are essential for maintaining the osmotic balance within cells and tissues.
  4. They often participate in ionic bonds, forming salts with positively charged cations.
  5. The formation of anions is a key concept in understanding acid-base chemistry and pH balance in biological systems.
