Electrons are a type of subatomic particle with a negative charge. Protons and neutrons have approximately the same mass, but they are both much more massive than electrons (approximately 2,000 times as massive as an electron). The positive charge on a proton is equal in magnitude to the negative charge on an electron..
Consequently, do protons and electrons have the same number?
The number of protons in the nucleus of the atom is equal to the atomic number (Z). The number of electrons in a neutral atom is equal to the number of protons. The mass number of the atom (M) is equal to the sum of the number of protons and neutrons in the nucleus.
do electrons have the same mass as neutrons? Even though electrons, protons, and neutrons are all types of subatomic particles, they are not all the same size. When you compare the masses of electrons, protons, and neutrons, what you find is that electrons have an extremely small mass, compared to either protons or neutrons.
Moreover, what is the mass of electron and proton?
Nuclear Binding Energy and the Mass Defect
| Particle | Mass (kg) | Mass (Mev/c2) |
| 1 atomic mass unit | 1.660540 x 10-27 kg | 931.5 MeV/c2 |
| neutron | 1.674929 x 10-27 kg | 939.57 MeV/c2 |
| proton | 1.672623 x 10-27 kg | 938.28 MeV/c2 |
| electron | 9.109390 x 10-31 kg | 0.511 MeV/c2 |
Why do all electrons have the same mass?
The current "explanation" is that there is a single electron field across the universe, and all electrons and positrons are quantum excitations of that field, and so come in units of integer electrons of a given mass and charge. By the way, in some sense, not all electrons have the same rest mass.

What is atomic mass number?
The mass number (symbol A, from the German word Atomgewicht [atomic weight]), also called atomic mass number or nucleon number, is the total number of protons and neutrons (together known as nucleons) in an atomic nucleus. The mass number is different for each different isotope of a chemical element.Do protons have a positive charge?
Protons and neutrons are in the center (nucleus) of the atom. Proton—positive; electron—negative; neutron—no charge. The charge on the proton and electron are exactly the same size but opposite. The same number of protons and electrons exactly cancel one another in a neutral atom.Why is proton positively charged?
A proton has positive charge of 1, that is, equal but opposite to the charge of an electron. The charge is believed to be from the charge of the quarks that make up the nucleons (protons and neutrons).What is the space between electrons?
The empty space between the atomic cloud of an atom and its nucleus is just that: empty space, or vacuum. That's the simple answer, but there are a few subtleties: 1) Sub-atomic particles such as electrons, protons and neutrons need to be treated as quantum objects.How do you get the number of neutrons?
This means to find the number of neutrons you subtract the number of protons from the mass number. On the periodic table, the atomic number is the number of protons, and the atomic mass is the mass number.What is the charge of a proton?
Proton Charge While a proton has a charge of +1, or 1e, an electron has a charge of -1, or -e, and a neutron has no charge, or 0e. 1 elementary charge is equal to: 1.602 x 10^-19 coulombs.How many neutrons does nitrogen have?

Why do electrons and protons not attract?
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.What has a mass of 1 amu?
An atomic mass unit (symbolized AMU or amu) is defined as precisely 1/12 the mass of an atom of carbon-12. The carbon-12 (C-12) atom has six protons and six neutrons in its nucleus. In imprecise terms, one AMU is the average of the proton rest mass and the neutron rest mass.What is the mass of electrons in amu?
0 amu
Do Photons have mass?
Light is composed of photons, so we could ask if the photon has mass. The answer is then definitely "no": the photon is a massless particle. According to theory it has energy and momentum but no mass, and this is confirmed by experiment to within strict limits.Who discovered Proton?

What is an a particle?
Particles are tiny bits of matter that make up everything in the universe. In particle physics, an elementary particle is a particle which cannot be split up into smaller pieces. Atoms and molecules are called microscopic particles. Subatomic particles are particles that are smaller than atoms.What is the value of electron?
Since the value of the elementary charge is roughly 1.602 x 10-19 coulombs (C), then the charge of the electron is -1.602 x 10-19 C. When expressed in atomic units, the elementary charge takes the value of unity; i.e., e = 1. Thus, the electron's charge can be denoted by -e.What is the mass of deuteron?
But the mass of the deuteron is 1875.6 MeV, implying that, upon energy grounds, it is stable agains such a decay. The free neutron yields an energy of 0.78 MeV in beta decay, but the 2.2 MeV binding energy of the deuteron prevents its decay.What is smaller than an electron?
There are particles that are smaller than electrons and the smallest particles that we know of are quarks. But we also know that electrons are not made of quarks so they are not more granular than electrons. Unless “more granular” means “smallest”. Then the answer is: quarks.How do you find the mass number?
Together, the number of protons and the number of neutrons determine an element's mass number: mass number = protons + neutrons. If you want to calculate how many neutrons an atom has, you can simply subtract the number of protons, or atomic number, from the mass number.Do electrons have mass?
Electrons belong to the first generation of the lepton particle family, and are generally thought to be elementary particles because they have no known components or substructure. The electron has a mass that is approximately 1/1836 that of the proton.Why do neutrons have no charge?
A neutron has no net charge because the charge of the quarks that make up the neutron balance each other out.
