Which statement is most likely true?

ernest rutherford’s experiment led to the nuclear model of the atom.
ernest rutherford’s experiment established the plum pudding model of the atom.
robert millikan’s postulates form the most accepted theory for the atomic structure.
robert millikan’s results had little impact on determining of the charge of an electron.

The first statement is correct because Rutherford was the first discovered the nucleus by firing alpha particles at a gold foil and finding that most particles went through the foil because their is empty space around the small dense nucleus and a few alpha particles were deflected because of the nucleus. 

I also have a chemistry questions and would appreciate it if you answered it thanks! 

Gallium melts near room temperature and has one of the largest  liquid  ranges of any metal, so it has found use in high temperature thermometers.
