Which particles make up the nucleus of an atom? protons and electrons neutrons and electrons protons only protons and neutrons neutrons only

Answer : The correct option is, protons and neutrons.

Explanation :

As we know that an atom is the smallest unit of a matter that consist of three subatomic particles. The subatomic particles are electrons, protons and neutrons.

The protons that are positively charged and the neutrons that are neutral that means no charge are located inside the nucleus or center of the nucleus of an atom. In the nucleus, the mass of the an atom is concentrated and the electrons that are negatively charged located around the nucleus.

Hence, the particles make up the nucleus of an atom are protons and neutrons.

adding or remove a gaseous reactant or product changes the concentrations. if the concentration of reactant or product is increased, the system will shift away from the side in which concentration was increased (i.e. if the concentration of reactants is increased, the system will shift toward the products. if more products are added, the system will shift to form more reactants). conversely, if the concentration of reactant or product is decreased, the system will shift toward the side in which concentration was decreased (i.e. if reactants are removed, the system will shift to form more reactants. if the concentration of products is decreased, the equilibrium will shift toward the products).
