complementary ion的意思|示意

'

Complementary ions are two ions that, when combined, form a neutral species. For example, if a positively charged sodium ion (Na+) combines with a negatively charged chloride ion (Cl-), the two ions will form a neutral compound, which is known as salt (NaCl).

In chemistry, complementary ions are very important. For example, when a substance is dissolved in water, the atoms become ions, which can then interact with other ions. This process is known as electrolysis and it is used to break up molecules into two or more ions. For example, if a molecule contains two hydrogen atoms (H2) and one oxygen atom (O), then the two hydrogen atoms will become positively charged hydrogen ions (H+), while the oxygen atom will become a negatively charged oxygen ion (O–). The combination of these two ions will form a neutral compound (H2O).

In biology, complementary ions are also very important as they provide the cell with necessary nutrients, vitamins and minerals. For example, calcium is important for muscle contractions and nerve impulses, while potassium is important for the maintenance of fluid balance. When these two ions are combined, they form a neutral compound (Ca2+ and K+).

Complementary ions can also be used to help determine an ionic bond. An ionic bond is formed when two atoms of opposite charge attract each other and form a covalent bond. Complementary ions form when two atoms with the same charge attract each other, creating a strong ionic bond.

In conclusion, complementary ions, when combined, form a neutral species. They are used in many areas of chemistry and biology and play an important role in the formation of ionic bonds.
