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)
Aluminum foil does not contain BPA. BPA is a chemical compound that is used in some plastics, but it is not present in aluminum foil.

Aluminum foil is typically around 0.2 atoms thick. At this scale, we are dealing with the thickness in terms of angstroms (1 angstrom = 0.1 nanometers). So, the thickness of aluminum foil is very small, at the atomic scale.
A pure metal is just that; that metal, thus pure metals contain just one metal. For example aluminium foil contains just aluminium atoms. Alloys are one or more metals/elements that make up the metal, e.g C and Fe in steel.

Experiments with gold foil indicated that atoms have a small, dense nucleus at their center, surrounded by mostly empty space with electrons orbiting around the nucleus. This led to the development of the nuclear model of the atom, proposed by Ernest Rutherford.

Ernest Rutherford's gold foil experiment in 1909 provided evidence that atoms contain mostly empty space with a dense center (nucleus). By observing how alpha particles were deflected when they passed through gold foil, Rutherford deduced that most of the mass of an atom is concentrated in a small, positively charged nucleus, with the rest being empty space.

Aluminum foil has metallic bonds, where aluminum atoms share their electrons with surrounding atoms to form a uniform structure. This differs from ionic bonds where electrons are transferred between atoms or covalent bonds where electrons are shared between atoms.

No, aluminum foil does not contain nickel. Aluminum foil is made of aluminum, while nickel is a different metal with its own unique properties.
Ernest Rutherford's hypothesis was that atoms have a dense nucleus at their center with electrons orbiting around it. He tested this hypothesis through the famous gold foil experiment, where he bombarded thin gold foil with alpha particles to study how they were deflected by the atoms in the foil.
