Fractional Distillation
Who Discovered That The Plum Pudding Model Was Wrong?
Ernest Rutherford
, Who Devised An Experiment That Proved The Existence Of The Neutron?
Niels Bohr
Why Did Mendeleev Leave Gaps In His Table Of Elements?
To Ensure That Elements With Similar Properties Stayed In The Same Groups. The Gaps Indicated The
Existence Of Undiscovered Elements And Allowed Mendeleev To Predict What Their Properties Might Be
How Are The Group Number And The Number Of Electrons In The Outer Shell Of An Element Related?
The Group Number Tells You How Many Electrons Are In The Outer Shell Of An Element. E.G. Sodium Is
In Group 1 Therefore It Has 1 Electron On Its Outer Shell
