What is the proton neutron and electron number does a promethium have?
Wiki User
∙ 14y ago
Promethium has 61 protons and electrons.
For each isotope the number of neutrons is different. Number of neutrons = Mass number of a Pm isotope - 61

Does an electron have more maas than a proton or neutron?
an electron is much lighter than a proton or neutron.
What is the number of protons electrons and neutrons in platinum?
the number of proton neutron and electron proton(+p) and electron(-e) has 78 and neutron has 116, 117, or 118 (or from 112 to 120, including synthetic isotopes)
How does the mass of a electron compare to the mass of a proton and neutron?
Mass ratio proton (neutron)/electron: 1 836
How does the mass of a proton compare to the mass of a neutron and an electron?
Mass ratio proton (neutron)/electron: 1 836
What is the mass of an electron compared to the mass of a proton or neutron?
Mass ratio proton (neutron)/electron: 1 836
If a proton had a mass of 1 what is the mass of an electron and neutron relative to the mass of the proton?
If a proton would be 1, an electron would be 0.000544. An electron is 1,836 times lighter than a proton. A neutron would be 1.001 as a proton is 99.86% the mass of a neutron
What subatomic particles are closest in mass proton and neutron neutron and electron proton and electron electron and ion?
Mg+2 and Br-1
What is the size of electron proton and neutron?
The electron is the smallest having about 1/1836th the mass of a proton or neutron, which means that basically an electron has no mass. The neutron and proton weigh the same both having a mass of 1.
How many particles do the atom have?
5, electron, proton, neutron, nucleus, and electron cloud.
Which charge contributes to the proton electron and neutrion?
The three principal particles of an atom are the proton, electron and neutron. The proton and electron have +1 and -1 charges respectively. The neutron does not have a charge.
Is an example of an electrostatic force acting in an atom neutron attracting an electron a proton attracting an electron an electron attracting another electron a neutron attracting a proton?
This is valid only for the attraction between a proton and an electron.
