Elements combine in three general ways. In<u> ionic</u> compounds, electrons are transferred from one element to the other, whereas in <u>covalent </u>compounds, electrons are shared between atoms. Third, in <u>metallic </u>bonding, electrons are shared between a large number of atoms in an electron sea.
Ionic compounds are compounds in which a free electron is transferred to another atom and a bond is formed. Ionic bonds occur in metal ions.
In liquid compounds, covalent bonds are formed. In covalent bonds, electrons are shared with each other,
The third type of bond is the metallic bond. In this type of bond, atoms are packed tightly and a free electron pool travels in between them.

Answer:
Active transport
Explanation:
Sodium-potassium pumps are examples of Active type of cellular transport. Sodium potassium pump exchanges sodium ions from potassium ions through the plasma membrane of animal cells.
Whereas Active transport can be defined as movement of ions and molecules across a cell membrane to the region of higher concentration with the help of enzymes and energy.
