1 mole Al = 6.022 x 1023 atoms Al
0.2mol Al x 6.022 x 1023 atoms Al/1mol Al = 1 x 1023 atoms Al (rounded to 1 significant figure)

How many moles are in a gram of aluminum foil?
27g
How many atoms thick is aluminum foil?
Depending on the thickness of the foil.
What is the electron configuration for aluminum foil?
The electron configuration for aluminum atoms, which is 1s22s22p63s23p1.
Who is the scientist who suggested that atoms contain a hard core containing most of the mass of an atom?
The scientist that suggested and proved that atoms contained a nucleus in which most of the weight of the atom was contained (in a very small volume) was Ernest Rutherford, in 1909. This was shown in the 'gold foil' experiment. This was made by shooting positively charged alpha particles, or a positively charged helium atom (2 protons, 2 nuetrons). these then when shot at the gold foil. some of the alpha particles just passed through the gold foil, but some were deflected. this proving that some hit the nucleus while others did not.
What did Rutherford's gold foil experiment tell about atoms?
that the atom mostly consisted of empty space.
Experiments with gold foil indicated that atoms?
contain a positively charged, dense center

What kinds of atoms are in aluminum foil?
aluminum
Which type of particles did Rutherford fire at gold foil?
atoms
When did Rutherford discover that atoms contain mostly empty spaces?
most of the alpha particle pass through the gold foil without deviation and the mass of electron are very small
Which statement is consistent with the results of Rutherford's gold foil experiment?
In Rutherford's gold foil experiment atoms are mostly empty space.
Difference between blister pack and strip pack?
Blister Packing contain PVC foil (0.25mm) and Alu. foil (0.025mm) Strip Packing contain Bothside Poly alu. foil (0.30mm)
What is the name of the scientists who first proposed that atoms have a nucleus?
Ernest Rutherford, following the "gold foil" experiment.
Who said atoms contain mostly empty space?
Anybody who knows much about atoms and is willing to ignore virtual particles. The credit for actually discovering this should probably go to Rutherford. (Or Rutherford, Geiger, and Marsden ... Geiger and Marsden actually did the experiment in Rutherford's lab, and Rutherford was the one who explained the results.)
Who discovered that atoms were mostly empty space?
Rutherford, with his gold foil experiment.
What is the electron configuration for aluminum foil?
The electron configuration for aluminum atoms, which is 1s22s22p63s23p1.
