A quantum mechanical system or particle that is bound—that is, confined spatially—can only take on certain discrete values of energy. This contrasts with classical particles, which can h...
As an electron approaches a nucleus from infinity, it becomes 'bound' - it is attached to the nucleus, if you like. In this bound state, the electron occupies what is ...
A Hydrogen atom consists of a proton and an electron which are “bound” together – the proton (positive charge) and electron (negative charge) stay together ...
