Atom of Ernest Rutherford, bombarded a metal foil with alpha particles to observe how they scattered. They expected all the alpha particles to pass straight through with little deflection, because Thomson's model said that the charges in the atom are so diffuse that their electric fields could not affect the alpha particles much. However, Geiger and Marsden spotted alpha particles being deflected by angles greater than 90°, which was supposed to be impossible according to Thomson's model. To explain this, Rutherford proposed that the positive charge of the atom is concentrated in a tiny nucleus at the center of the atom.
Atom Bank Atom Bank Atom Bank is a digital financial company and challenger bank. It provides banking services through a smartphone app. It has no physical outposts. As a smartphone app-based bank, it does not have a traditional online banking outlet, as users must use the application to bank. Atom first secured its banking license in June 2015. The company publicly launched in April 2016. In March 2017 it raised £83 million in venture funding, which brought its total funding to over £200 million. On 9 March 2017, the bank experienced over 5,000 new customer signups in one day, a new record.
