What important discovery did Ernest Rutherford make?A.He found that light could make electrons flow in metals.B.He found that electrons were negatively charged particles.C.He found that the atom contained both protons and electrons.D.He found that the atom was made up of mostly empty space.

Use the evidence described to explainwhy Rutherford concluded that:a an atom contains a lot of spaceb there is a central area of positive charge.

Question 2 of 10What did Robert Millikan discover?A.He discovered the nucleus of the atom.B.He determined the radius of oil drops.C.He determined an electron's charge.D.He discovered that electrons orbited inside an atom.

which of the following is not correct about the discovery of atoms?1 pointplum pudding model is given by JJ Thomsonrutherford is also known as the father of nuclear physicsneutron is discovered by Neil bohrrutherford failed to explain why electron is not losing energy and falling into the nucleus

Recall what was interesting about the discoveries of rutherfordium and dubnium. Scientists still cannot synthesise them.1They were independently discovered by American and Soviet scientists.2They were the only elements to be discovered by mistake.3Scientists thought they were both the same element.

1.Rutherford’s ‘alpha (α) particles scattering experiment’resulted into discovery of(a) electron (b) proton (c) nucleus in the atom (d) atomic mass.
