What effect produced by changing the number of neutrons in the nucleus of an atom?
What differentiates one element from another (like Hydrogen from Helium) is the number of protons in the nucleus. When protons are added (as happens in nuclear fusion) or subtracted (nuclear fission), the element transmutes into another element.
When the number of Protons are changed, both the Electrons and Neutron (numbers) will change too. Protons are paired with electrons. Protons + Electrons = Neutrons, thus reinforcing that both the Electrons and Neutrons will change when the number of Protons has.

What is the principal effect of the presence of neutrons in the nucleus of an atom?
It is suposed that neutrons are necessary for the stability of the atomic nucleus.
What effect does changing the number of particles in an atom have on the atoms identity?
An atom is made of smaller particles called protons, neutrons, and electrons. Protons and nuetrons are in the nucleus. The number of protons in a nucleus is the atomic number and defines the type of element the atom forms. The number of neutrons determines the isotope of an element. For example, the carbon-12 isotope has 6 protons and 6 neutrons, while the carbon-14 isotope has 6 protons and 8 neutrons. If the numbe of protons were to change, it would no longer be carbon.
What effect would adding additional neutrons have on the force in a nucleus?
The additional neutrons don't exert electric forces. They do attract one another, and the protons, via the strong nuclear force.
Does the strong nuclear force have charges like the electromagnetic force does?
No. The strong nuclear force works through the exchange of a subatomic particle called a meson. Additionally, the strong nuclear force has to hold protons and neutrons together in the nucleus, so having a charge would have no effect on the neutrons.
What three factors effect the nuclear charge?
The stability of a nucleus depends on the ratio of protons to neutrons. It's not a simple ratio that's the same for all atomic numbers, it varies. For small atomic numbers, 1:1 is about right. For higher atomic numbers, more neutrons are needed.

Why is the decay time of free neutrons so much shorter than of bound ones?
When bound inside of a nucleus, the instability of a single neutron to beta decay is balanced against the instability that would be acquired by the nucleus as a whole if an additional proton were to participate in repulsive interactions with the other protons that are already present in the nucleus. As such, although free neutrons are unstable, bound neutrons are not necessarily so. The same reasoning explains why protons, which are stable in empty space, may transform into neutrons when bound inside of a nucleus.
Do protons repel protons in the nucleus of the cell if yes then how does the nucleus and atom stay and do not disintegrate?
protons and neutrons are both made of quarks each with their own +'ve and -'ve charges, at the close proximity that protons and neutrons are found their overall charges are no longer in effect it's the charges of the quarks within them that affect attraction and repulsion
What effect does losing a gamma ray have on the nucleus?
Losing a gamma ray does not change the number of protons or neutrons in the nucleus, so the nucleus remains the same element. However, the nucleus may be left in an excited state after emitting a gamma ray, and it typically returns to its ground state quickly by emitting the gamma ray.

Does the amount of empty space in an atom increase with more neutrons?
The atom is almost entirely empty space. Electrons are almost not even particles, they're so small and so often behave like waves, and the nucleus (where the protons and neutrons are) is only 1/10000 of the atom. The size of a given element is mostly controlled by two things: the number of energy levels that contain electrons, and the total number of protons pulling at the number of electrons. Because neutrons have no charge, they have little effect on the size of the atom.
Why do scientists say that electrons most effect an atom's size while protons and neutrons most effect an atom's mass?
electrons buzz around the atomic nucleus. low level/lower energy electrons have orbits tighter/closer to the nucleus, but higher/more excited electrons have a broader orbit ie: further away from the nucleus. this looks a little like a small or big cloud around the nucleus, making it look bigger. the protons and neutrons form the nucleus, and the futher along the periodic table you move, the more of them there are in each atom. because they have mass, more of the means more mass, and I'm pretty sure that they have more mass than electrons. it is said that protons and neutrons are made up of subatomic particles, like quarks, which have no mass. quantum physicists at the moment claim that bosons hold these quarks together, and another undiscovered boson gives them mass
Which subatomic particle causes the mass number to change but has no effect on the identity of the element?
Neutrons are the subatomic particles that contribute to the mass number of an atom without affecting its chemical identity. They can be added or removed from the nucleus during nuclear reactions, altering the atom's isotopic mass without changing its elemental properties.
