This scientist led a series of experiments that used high speed lightweight atoms called alpha particles to bombard very thin pi
eces of gold foil. Some of the alpha particles went straight through the foil, but a few alpha particles bounced back. The scientist used this information to hypothesize that an atom is made of a tiny dense nucleus surrounded by a region of mostly empty space. A. Democritus

Ernest Rutherford was a renown Physicist and a Physics Nobel price winner. In 1911 he proposed the planetary model of atom. When the experiment were conducted he proposed that the atom had a charged nucleus and are surrounded by electrons. This finding was the basis for subsequent studies on radioactivity.
The protons inside an atom's nucleus help bind the nucleus together. They also attract the negatively charged electrons, and keep them in orbit around the nucleus. The number of protons in an atom's nucleus determines which chemical element it is.
1 mol of ideal gas at STP occupies 22.4 (or 22.7 depending on the convention being used for STP) liters in volume. I will use 22.4 so 17.88*22.4 = 400.5 L
