Protons push away from each other because they are both positively charged. Much like the positive ends of magnets repel each other. Fortunately, protons are held together by quarks, leptons and gluons.
Yes; any particle that is contained in an atom (proton, neutron, electron; these are referred to as p,n,e) can leave. Protons and neutrons will only leave an atom if the total energy of the nucleus is greater than the energy of its greatest stable energy. Generally speaking, this means that protons and neutrons have to be able to attract one another via the Strong Force by a greater amount than the repulsive force experienced by protons that are all the same charge. Neutrons act as buffers where they increase the distance between protons and thus lower the repulsive force of protons. If the nucleus is too big for the Strong Force to take effect or if the repulsive electromagnetic force is stronger than the Strong Force, then the nucleus will decay and the atom will break apart into different atoms whose net energy and particle count will be the same as the original atom. Another way to break up the nucleus is to (rather violently) insert another atom into the nucleus via a particle accelerator, which may force a decay.
Electrons that leave are much simpler. In a process known as ionization, all that is necessary for electrons to leave is for the electrons to have a greater energy than their attraction to the nucleus. This attraction is more than just the electromagnetic attraction (remember that like charges repel and different charges attract) and requires an understanding of quantum mechanics, which is outside of the scope of this question.
In short: Yes, electrons can leave. The previously neutral atom is known as a cation, which will have a positive electric charge equal to the missing number of expected electrons.
Applications: lights, television, electricity, and others.
decrease because less energy is needed to push them apart than is needed to put them together
No they cannot its impossible
protons and neutrons repel each other. The protons in the nucleus repel each other...APEX
56 protons.
The protons in an atomic nucleus do repel each other, but they are held together by the Strong Nuclear Force, which is stronger than the electrical force that pushes them apart. Within the nucleus, the Strong Force is more than 100 times stronger than the electric force.
Well a neutron and a nucleus are different from each other because a neutron is a particle within the atom nucleus with a neutral charge The nucleus however is all the neutrons and the protons. Nucleus could also mean the nucleus of a cell, which is commonly refered to as well, but is completely different.
An element with 16 protons in the nucleus of each atom.
protons and neutrons repel each other. The protons in the nucleus repel each other...APEX
Protons push away from each other because they are both positively charged. Much like the positive ends of magnets repel each other.
They don't touch each other, they are all blocked by neutrons in the nucleus, that is why protons don't just repel each other and the nucleus doesn't fall apart.
It causes the protons in the nucleus repel each other.
protons and neutrons repel each other. The protons in the nucleus repel each other...APEX
The protons in the nucleus repel each other by the electromagnetic force, but this is nullified by the strong force.
Since the electrons are negatively charged and the nucleus is positively charged due to presence of protons, they attracted towards each other by the electrostatic force of attraction and thus electrons keep revolving around the nucleus and do not run away
In the nucleus of an atom, the protons repel each other due to their like charges. However, the strong force keeps protons from flying apart, keeping the protons inside the nucleus.
56 protons.
electron - electron cloud protons and neutron- nucleus
The protons in an atomic nucleus do repel each other, but they are held together by the Strong Nuclear Force, which is stronger than the electrical force that pushes them apart. Within the nucleus, the Strong Force is more than 100 times stronger than the electric force.
Its atomic number. In other words the number of positive protons in the nucleus of each atom and the number of negative electrons surrounding the nucleus of each atom.
