The force that holds two atoms together is called a(n) _______
gravity
nuclear force
reaction
chemical bond
The force that holds two atoms together is called a chemical bond.
What is a chemical bondA chemical bond is a force of attraction that holds two or more atoms together to form a stable molecule or compound. Atoms consist of a positively charged nucleus containing protons and neutrons, surrounded by negatively charged electrons. In order to achieve a stable electronic configuration, atoms can undergo chemical bonding to fill their outermost electron shells.
Chemical bonds play a vital role in determining the physical and chemical properties of substances. The strength and type of bond between atoms influence factors such as boiling points, melting points, solubility, and reactivity. Understanding chemical bonds helps explain how different substances interact and form new compounds.

Use at least three complete sentences to explain how global wind patterns such as the prevailing westerlies in the northern hemisphere would be impacted if the rotation of Earth stops.(5 points)
Answer:
If the Earth did not spin on its axis, the atmosphere would only circulate between the poles and the equator. And if this happens, the very same thing is bound to happen over again. That is, the atmosphere would only circulate in a back-and-forth pattern between the poles and the equator over and over.
