The element is hydrogen and the isotope is tritium (1H3)
There is an isotope of hydrogen called 'protium', which only has 1 proton and 1 electron, with no neutron.
Hydrogen consists of one proton and one electron. It is the simplest and most abundant element in the universe.
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.
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.
Mass ratio proton (neutron)/electron: 1 836
Mass ratio proton (neutron)/electron: 1 836
Mass ratio proton (neutron)/electron: 1 836
The only element that does not have a neutron in its nucleus is hydrogen-1, which consists of one proton and one electron.
Mg+2 and Br-1
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
Proton's have a positive charge, neutron'shave a neutral charge, electron's have a negative charge
A proton and neutron are both composed of three quarks. An electron is a fundamental particle and is not composed of smaller particles.
