In a chemical bond between two or more atoms, what creates the bond?
a. electron pairs
b. the nucleus
c. diametric energy force
d. proton pairs

ANSWER:

The correct option is A- Electron pairs.

EXPLANATION:

In a chemical bond, the electron pairs are responsible for the formation of a bond. The electrons are gained or lost from atoms so that they can enter into a bond with another atom.

The electrons of an atom may be gained by another atom to maintain the atom in a stable condition. This sharing of electrons is what results in chemical bonds in atoms. Usually, the electrons of the outermost shell of atoms are responsible for chemical bonding.  

he movement of air through earth's or any planet's atmosphere is called wind, and the main cause of earth's winds is uneven heating by the sun. this uneven heating causes changes of atmospheric pressure, and winds blow from regions with high pressure to those with low pressure.
