Why atoms with larger atomic number are unstable?
The bigger the atom the more shells or layers it will have. This means that the outer atoms are further from the centre and so the pull on them from the centre is less strong and so they break up more easily.
Why does every element except hydrogen need at least one neutron in its neucleus?
Every element except hydrogen needs at least one neutron in its nucleus because it needs attractive force from the strong nuclear interaction to counter the electrostatic repulsion between the protons.
According to modern atomic theory where is most of the mass of an atom located?
Most of the mass of an atom is located in the nucleus, which is made up of protons and neutrons. The nucleus is located at the center of the atom. Electrons, which have much less mass compared to protons and neutrons, orbit around the nucleus in electron clouds.
The fewer electron shells the shielding of electrons from the nucleus.?
less
What change to the nucleus when it loses one electron?
Just making sure, first off, that you realize electrons are not in the nucleus. They float in the empty space around the nucleus, of an atom. But if your asking what happens to the atom once it loses an electron, the atom then has a positive charge, and becomes a positive ion. The atomic size[of the atom alone] becomes smaller due to the greater pull the protons are able to have on the electrons.
The force of repulsion between protons in the nucleus of small atoms is?
Less than

Why you can not squish the atom?
Squish means extracting out the material inside by pressing it ..... just because atom has a nucleus in which there present neutrons (charge-less) and protons (positively charged). protons have strong electrostatic forces of repulsion between them that makes them cover a certain area which make nucleus...around nucleus there are electrons revolving around. having negative charge on them attracted by the nucleus...but electron also have a strong fore of repulsion among themselves which force them to cover the area....due to the presence of these forces it is impossible to squish an atom.
Is the nuclear force a force of attraction or repulsion or both?
It is only attractive in nature. I am not sure which nuclear force you talk about. Electrical forces of the nucleus are repulsive to the positively charged. There are "strong forces" and the like which are attractive.
Where is most of potassium atoms mass located?
Most of the mass of a potassium atom is located in its nucleus, which contains protons and neutrons. The electrons in the electron cloud surrounding the nucleus have significantly less mass compared to the nucleus.
Why does every element except hydrogen need at least one neutron in its neucleus?
Every element except hydrogen needs at least one neutron in its nucleus because it needs attractive force from the strong nuclear interaction to counter the electrostatic repulsion between the protons.
The stronger force between protons and neutrons in a small nucleus and a larger nucleus?
In a small nucleus, such as oxygen, xenon, or any of the lighter elements, the strong force generated by the protons and neutrons is stronger than the repulsion between protons, and the nucleus holds together. In a larger nucleus, such as uranium, curium, or the heavier elements, the strong force isn't strong enough to hold it together, and the electromagnetic force pulls it to pieces.
The instability that occurs in larger nuclei is caused by the fact that?
the strong nuclear force doesn't fall off much in a small nucleus
An electron is much larger than an atom?
This statement is not correct. An atom is made up of a nucleus (containing protons and neutrons) surrounded by electrons. Electrons are subatomic particles that are much smaller and have much less mass than the nucleus of an atom.

What is the difference between the three subatomic particles?
The main differences are proton and neutron are in the nucleus, electrons are outside of the nucleus. The weight of an electron is between a hundred and a thousand times less of that of a proton and neutron and the charge on a proton is positive, neutron is neutral and electron is negative
