What evidence lead rutherford to propose that the atom had a nucleus?

When he shot radiation through gold foil, some of the radiation shot back, some went directly through, and some slight angled off.

Explanation:

He knew that the radiation that had gone all the way through had not hit anything.

He knew that the radiation that came directly back must have hit a big nucleus.

He knew that the radiation that angled slightly off must have hit a smaller, orbiting particle (electrons).

MgO, is similar to the bonding in barium chloride, BaCl2. The bonding in each compound involves a transfer of valence electrons from the metal to the nonmetal; both metals lose all of their valence electrons
