Ernest Rutherford contributed to the atomic theory by discovering that the atom is mostly empty space.

He can to that conclusion because he fired alpha particles at gold foil, which was so thin that it was only around .00004 cm thick, and while almost all shot straight through, some actually bounced back!

He likened it to shooting a 15-inch round(bullet) at tissue paper, only to have it bounce right back at you! Based on this, he theorized that the atom is mostly empty, which is why a majority of the particles passed right through, but in the very center of the atom there is a super-dense structure called a nucleus that held a majority of the atom's mass. This super-dense mass would be more than massive enough to deflect the particle, should they collide.

Answer(s):

1st: Clerics and Kings on the top of the hierarchy, Farmers and Warriors beneath them, Fishermen on the third layer, Weavers and Leatherworkers on the fourth layer and Smiths and Griots at the bottom layer.

2nd: The political systems of African kingdoms shared similarities with European kingdoms. The king, such as Mansa Musa of Mali and Sonni Ali of Songhay, had near absolute power and there was no separation of power. The king and his councilors and advisors carried out executive, legislative, and judicial functions.

3rd: First, the early African kingdoms and empires relied heavily on trade with other people. Besides the trade in ivory, gold, and other commodities identified earlier, produce from agriculture was also exchanged in the form of cash crops. These trade relations put them at the center of the economy of the east and west.

Hope this helped ;)
