The mass of a neutron is approximately the mass of a proton...so
= 1.66 X 10 -27 kg
-------------------------------approximate neutron mass
Electron mass.
= 9.109 X 10 -31 kg
-----------------------------------so,
1.66 X 10 -27 kg/9.109 X 10 -31 kg
= about 1822 electrons to equal mass of neutron
================================
no electrons have mass, about 1/1800 that of a proton or neutron.
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.
Electrons have a negative charge, are much smaller than protons and neutrons, and are located in orbitals around the nucleus. Protons have a positive charge, are located in the nucleus of an atom, and determine the element's identity. Neutrons have no charge, also reside in the nucleus of an atom, and help stabilize the nucleus.
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
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.
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.

A neutron don't contain electrons; the mass of an electron is approx. 1/1850 of the neutronic mass.
A neutron has a mass approximately equal to that of a proton, which is about 1,836 times the mass of an electron.
It would take about 1836 electrons to equal the mass of one proton. This is because the mass of a proton is approximately 1836 times greater than that of an electron.
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.
The mass of neutron is similar to the mass of proton, but not equal !
The mass of a proton is equal to a neutron.
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.
Neutron
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.
no electrons have mass, about 1/1800 that of a proton or neutron.
