Is it true that Unlike protons or neutrons electrons have no mass?
no electrons have mass, about 1/1800 that of a proton or neutron.
How many proton neutron electrons in a hydrogen isotope with mass of 2?
1 proton and 1 neutron is needed because the 2 in hydrogen 2 refers to the atomic mass and protons and neutron have a mass of about 2 daltons each.
How can the number of proton neutron and electron be calculated to get atomic number and atomic mass?
atomic number is the amount of protons, equal to the atomic number, the electrons, minus the mass number atomic number is the amount of protons, equal to the atomic number, the electrons, minus the mass number atomic number is the amount of protons, equal to the atomic number, the electrons, minus the mass number
What features do electrons protons and neutrons have?
The two important characteristics of a neutron are its mass and charge. These are described below. 1) Mass of neutron. The mass of a neutron is equal to mass of a proton. The relative mass of neutron in 1 u. the absolute mass of a neutron is 1.6 * 10^-24 gram. 2) Charge of neutron. Neutron has no charge. It is electrically neutral. The two important characteristics of a Proton are its mass and charge. These are described below. 1) Mass of proton. The Proton is actually a hydrogen atom which has lost its electron. Since mass of an electron is very small, we can say that mass of proton is equal to mass of a hydrogen atom. The relative mass of neutron in 1 u. the absolute mass of a neutron is 1.6 * 10^-24 gram. 2) Charge of proton. The charge of a proton is equal and opposite to the charge of an electron. So absolute charge of a proton is 1.6*10^-19 coulomb.
Is there any relationship between atomic mass and number of proteins and electrons?
Yes, there is a relationship between atomic mass and the number of protons and neutrons in an atom. The atomic mass is approximately equal to the sum of the number of protons and neutrons in an atom, as electrons have negligible mass compared to protons and neutrons. The number of electrons in a neutral atom is equal to the number of protons, in order to maintain a balanced charge.
How many electrons does it take to equal the mass of one neutron?
One neutron is approximately equal in mass to one proton. Since an electron is much smaller in mass compared to a neutron or a proton, it would take a large number of electrons to equal the mass of one neutron.
How many electrons would be needed to equal the mass of one neutron?
about 2000
How many electrons are in a neutron?
A neutron don't contain electrons; the mass of an electron is approx. 1/1850 of the neutronic mass.
Does a neutron have the same mass as an electron or a proton?
A neutron has approximately the same mass as a proton. Electrons have much lower mass.
How many electrons does it take to equal to the mass of one proton?
electrons are a 2000th of the mass of a proton/neutron. Because of this very low mass, electrons dont affect the mass number of elements on the periodic table
Which subatomic particle is nearly equal to the masses of the other two subatomic particles added together?
The neutron has a mass that is nearly equal to the combined mass of a proton and an electron. This is due to the fact that the neutron is slightly heavier than the proton, while the electron has a much smaller mass.
Is the mass of a neutron the same as?
The mass of neutron is similar to the mass of proton, but not equal !
What is equal to mass of a proton?
The mass of a proton is equal to a neutron.
How many electrons equal the mass of one Proton?
1836 electrons equal the mass of 1 proton. A proton has a mass of 1.0073 amu, a neutron 1.0087 amu, and an electron 5.486 x 10-4. So, it would take 1836 electrons to equal the mass of 1 proton.
What has mass that is about equal to the mass of a proton?
Neutron
How does the mass of the nucleus compared to the mass of electrons?
The mass of a nucleus varies according to the atomic number (ie according to what element it is). For hydrogen , the simplest nucleus, the combined mass of the one proton and the one neutron would be equal in mass to 3672 electrons.
Is it true that Unlike protons or neutrons electrons have no mass?
no electrons have mass, about 1/1800 that of a proton or neutron.
