What does a strong nuclear force do in an atom?
a. it repels electrons from other electrons.
b. it repels protons from other protons.
c. it attracts protons and neutrons.
d. it attracts protons and electrons.

Option (c) is the correct answer.

Explanation:

It is known that an atom contains protons, electrons and neutrons.

Protons and neutrons reside inside nucleus of the atom whereas electrons revolve around the nucleus.

Protons have positive charge, neutrons have no charge and electrons have a negative charge.

So, inside the nucleus protons repel each other due to the same charge. Therefore, a greater force acts on the nucleus which helps to overcome the repulsive force force between the protons inside the nucleus and this force is known as nuclear force.

Thus, we can conclude that a strong nuclear force in an atom attracts protons and neutrons.

im doing test rn im going with 2 but ill give answer if itss wrong,   : )

rosa was looking for patterns to predict the products of chemical reactions. she recorded three similar decomposition reactions in the table.she should record 2licl + 3o2.

in the last row of the table. it is the thermal decomposition of chlorate lithium, hence, she should record these products as: lithium chloride ( 2licl ) and oxygen ( 3o2 )   2 > 2 licl + 3o2.
