Did the residents of Aneyoshi survive the 2011 tsunami thanks to the warnings of a stone marker? As for "how many shells the atom has," I already said that it has an infinite number of empty ones. The maximum number of electrons that an energy level can hold is determined from the formula 2n^2 equals the total number, where n is the energy level. If two atoms have complementary electron patterns, they can react and form a chemical bond, creating a molecule or compound. I know they are relatively distinguishable based upon the axis on which they are oriented. The Bohr model is useful to explain the reactivity and chemical bonding of many elements, but it actually doesnt give a very accurate description of how electrons are distributed in space around the nucleus.
