Which particles give the nucleus its posyive charge

Explanation:

Nucleus of an atom consists of two sub-atomic particles.These are protons and neutrons. On the other hand, electrons are the third sub-atomic particles which revolve around the nucleus of an atom.

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

Due to positive charge of protons, nucleus of an atom acquires a positive charge.

Therefore, we can conclude that protons are the particles give the nucleus its positive charge.

the potential energy of the reactants is 200j.

from the energy diagram, the energy of the product formed is 350j; this means that, this reaction is an endothermic reaction, because it absorbs energy from its environment.

in 1783 cavendish was working with his hydrogen gas and found that when he burned it and condensed the vapor it was water. this was very significant since it disproved the greek theory of elements completely since water was not a simple substance but the product of two gases. it was lavoisier who hearing of the experiment gave cavendish's gas the name hydrogen ("water-producer") and added that hydrogen burned by combining with oxygen and that water was a hydrogen-oxygen combination.
