Proton (particle)
The proton is a +1 electrically-charged subatomic particle. It is composed of three elementary particles: one down quark and two up quarks. Protons, along with neutrons, make up the nucleus of an atom.

How many protons neutrons electrons fe 2?
In a neutral iron (Fe) atom, the number of protons is 26, which is the atomic number of iron. The number of neutrons can vary, but the most common isotope of iron, Fe-56, has 30 neutrons. Since the atom is neutral, it will have an equal number of electrons as the number of protons, so it also has 26 electrons.
What is the same as the number of protons in its nucleus?
The number of protons in an atomic nucleus can change by several different mechanisms. Let's look at each one and see what happens.
In an atom with "too many" protons in its nucleus, that unstable atom can undergo what is called beta decay. There are two types of beta decay, and the one that could happen here goes by the name beta plus decay. In beta plus decay, a proton in the nucleus of that unstable atom transforms into a neutron. A positron and an antineutrino will be ejected from the nucleus, and the number of protons will have gone down by one. If you guessed that nuclear transmutation has just occurred where one element has transformed into another one, you'd be correct.
In some other unstable atoms with "too many" protons in the nucleus, that nucleus could under an electron capture event. In electron capture, the nucleus "pulls in" a nearby electron from one of the inner shells of the atom, and that electron "combines" with a proton to become a neutron. Again, the number of protons in the nucleus goes down by one, and nuclear transmutation has occurred.
Lastly, it is possible to bombard atomic nuclei with particles and "knock" protons out of a nucleus that is "hit" by the bombarding particles. There are a few different activities that are carried out in nuclear physics labs to do this, but we'll leave it here for now. Just keep in mind that beta plus decay and electron capture are the two primary methods that unstable nuclei undergo when they change the number of protons they have.

How many protons are in a ion with 86 electrons and a -1 charge?
A neutral atom has an equal number of protons and electrons. Protons are positively charged, and electrons are negatively charged. Therefore if you have an ion with a -1 charge, it has one extra electron. So your ion has 85 protons.
What isotope has 80 protons 80 electrons and 121 neutrons?
It is the Sr+2 ion. It is formed by a Sr atom.
How many protons and neutrons are in the nucleus of the atom?
No it is not the atomic number. We call it mass number.
How many protons neutron and electrons calcium?
Calcium has 20 protons and electrons and a number of neutrons different for each isotope..
Which has more protons in the nucleus C-12 C-14 or N-14?
N-14 has more protons. It contains one more proton than C.
What is the number of protons of sulphur?
Isotopes contains similar protons. So it contains 16 protons.
How can you use the periodic table to find the number of protons in one atom of an element?
valence electrons is the same as the number as the last digit in the group :)
How does a neutral atom change when its number of protons electrons or nuetrons change?
The element becomes a new element becuase the atomic number would change. For example if you added a proton to Hydrogen-atomic number 1, it would become helium-atomic number 2
What happens if protons are added to an element?
Addition or removal or protons are nuclear reactions and dont take place under normal conditions.
If a proton is removed, the previous atom is formed. If a proton is added, then the next atom is formed.
How protons and electrons in neon?
In an atom, 10 protons and 10 electrons. (# of protons = atomic number) =)
What reaction involves the exchange of protons and neutrons?
Outside of a particle accelerator they aren't. It is a nuclear reaction although an actual exchange of protons would be very unlikely (depending on what you mean by "exchange").
What are protons neutrons and electrons considered?
protons neutrons and electrons are considered tiny parts of matter
What is oxygen's number of protons electrons and charge?
The atomic number of oxygen is 8. So it has 8 protons, 8 electrons.
O-17 isotope has 9 neutrons (17 - 8 = 9)
What is the function of the brake?
Brake shoes are an integral part of the braking system of a motor vehicle. When a driver steps on the brake, the brake shoe is the mechanical part that he or she is ultimately controlling to bring the car to a stop. The backing of a brake shoe is a metal part, but the area that actually comes in contact with the brake is padded to provide friction to stop the car without damaging the brake itself. Brake shoes are found inside of drum brakes; disc brakes have calipers, which serve the same function in a slightly different way.
How many protons are there in an atom of argon?
Argon's atomic number is 18. thus, it has 18 protons and 18 electrons. Filling in the first 18 electron orbitals gives the configuration of 1s2 2s2 2p6 3s2 3p6. Thus, argon has 3 electron energy levels.
How many protons neutrons and electrons are in a neutral atom of 64Cu atomic number 29?

Phosphorus: 15 protons
Molybdenum: 41 protons
Aluminium: 13 protons
Cadmium: 48 protons
Chromium: 24 protons
Lead: 82 protons
How many protons neutrons electrons does Nacl have?
Na is Sodium and Cl is chlorine....i have the periodic table of elements here rite now but im too lazy to look at it to find the number of protons, but to find the number of neutrons, you subtract the atomic number which is the number of protons from the atomic mass...i learned bout this a few days ago in grade 9 science...hope i helped.. =)
