An atom is the smallest particle of  element that can take part in a chemical reaction. It consists of subatomic particles; electrons, neutrons and protons.Electrons are found in the energy levels while protons and neutrons are found in the nucleus.A proton is made up of three parts namely;Two up quarks One down quark, and The gluons The gluons are parts in which the quarks exchange, and this is how the strong nuclear forces works to keen them from getting out.
Answer from: Quest
answer
fusion: the energy source of stars. the energy released from the collapse of the gas into a protostar causes the center of the protostar to become extremely hot. when the core is hot enough, nuclear fusion commences. fusion is the process where two hydrogen atoms combine to form a helium atom, releasing energy.

Answer from: Quest
If a hydrogen atom is neutral, it must also have one electron. an oxygen atom (o) has an atomic number of eight (8). this means a neutral oxygen atom has eight protons and eight electrons. the element actium (ac) has an atomic number of 89, so it has 89 protons and 89 electrons in a neutral atom
