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
================================
Approx 1839 electrons.
the atomic number is equal to the number of electrons(-) and protons(+): that is why elements have no charge, as a neutron is neural
no electrons have mass, about 1/1800 that of a proton or neutron.
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.
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.
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
approximately 1840
about 2000
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
A neutron don't contain electrons; the mass of an electron is approx. 1/1850 of the neutronic mass.
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.
You may be referring to neutrons, protons and electrons. The neutron is heavier than the proton, but the difference is more like two electrons than one.
The mass of neutron is similar to the mass of proton, but not equal !
The mass of a proton is equal to a neutron.
A neutron has approximately the same mass as a proton. Electrons have much lower mass.
Neutron
the atomic number is equal to the number of electrons(-) and protons(+): that is why elements have no charge, as a neutron is neural
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.
