A hydrogen atom ... The electron and proton are attracted to each other. This attraction holds the atom together. It is not possible to locate the exact position of an electron, but the electron cloud ...

melting at - 259.2 C and boiling at - 252.7 C. The atomic configuration of the atom is (1s) 1, and it has an ionic radius of 0.208 nm. Three isotopes exist, hydrogen with one proton in the nucleus, ...

They have a radius of around 1 × 10 10 metres ... number of protons but different numbers of neutrons. There are three isotopes of hydrogen: hydrogen, deuterium (hydrogen-2) and tritium (hydrogen ...

When two hydrogen atoms get close enough, the electron from each atom feels an attraction from the proton in the other atom's nucleus. This attraction pulls the atoms together. The electrons end up ...
