Protons and electrons stick to each other as much as they can, but kinetic energy and quantum mechanics keep them from holding still. Protons and electrons are attracted to each other because the positive electric charge of the proton is attracted to the negative charge of the electron.
Why do protons and electrons attract?
Protons have a positive charge. Electrons have a negative charge. The charge on the proton and electron are exactly the same size but opposite. … Since opposite charges attract, protons and electrons attract each other.
Why are protons and electrons attracted to each other quizlet?
Since atoms are neutral, each atom has the same number of electrons as it has protons in the nucleus. … Protons repel each other (because like charges repel) and they attract electrons (because opposite charges attract).
What force attracts protons to electrons?
Basically, it contains a nucleus, holding some number (call it N) of positively charged protons, which is surrounded by a cloud (N) of negatively charged electrons. The force that holds the electrons and protons together is the electromagnetic force.
Why dont protons and electrons attract each other?
The reason that protons and electrons don’t just “stick together” is that as electrons are attracted closer and closer to protons, they lose potential energy (resulting in a “lower energy state”).
Why do protons and neutrons attract?
The strong nuclear force pulls together protons and neutrons in the nucleus. At very small distances only, such as those inside the nucleus, this strong force overcomes the electromagnetic force, and prevents the electrical repulsion of protons from blowing the nucleus apart.
Do protons attract other protons?
Protons do not attract each other; they repel each other all the time as you would expect from their all positive ‘like-charges’, but are kept from flying apart by gluons !! Gluons are the (intra-nuclear) strong nuclear force field exchange particles that hold the protons together.
How are protons and electrons different quizlet?
-Protons have a positive charge. -Electrons have a negative charge. -The charge on the proton and electron are exactly the same size but opposite. … The number of ELECTRONS must have the same number of protons.
Why are electrons attracted to the nucleus quizlet?
Electrons are attracted to the nucleus of an atom, so it takes energy to remove an electron. The energy required to remove an electron from an atom is called the first ionization energy. Once an electron has been removed, the atom becomes a positively charged ion.
What is the relationship between the masses of protons and electrons?
proton, stable subatomic particle that has a positive charge equal in magnitude to a unit of electron charge and a rest mass of 1.67262 × 10−27 kg, which is 1,836 times the mass of an electron.
Do electrons and protons repel each other?
Two protons (or two electrons) will repel each other. And again, the closer together they are, the stronger the repulsion. Now the nucleus of an atom is positively charged, while electrons are negatively charged. As a result, a nucleus will attract electrons.
Do electrons attract each other?
Electrons do not “attract” other electrons. If an electron is not moving away from another electron, it is because of some countervailing attractive force in the vicinity, such as that exerted by a proton.
What happens if an electron and proton collide?
When a proton and an electron collide, it’s called an electron capture. Electron capture is one of two processes in which a neutron is produced. The other process is a beta decay.
Do protons and neutrons attract?
Protons and neutrons aren’t electrically attracted to each other, but when they get close enough they can exchange particles called mesons and become bound together by the strong force. … The electrical repulsion still exists, so it’s easier to add neutrons to an atomic nucleus than it is to add protons.
Why do electrons repel each other?
When you have two electrons, the combined electric fields result in a higher and higher potential energy as they get closer. In order to minimize the potential energy, they repel each other (in the case of a positive and negative charge, potential energy is minimized by bringing them together, so they attract).
