Aparticular energy level in the hydrogen atom has e = -2.42 x 10-19 j. use bohr's model of the energy levels in hydrogen to calculate n for this level. recall that atomic number (z) of hydrogen is 1.

Why does earth rotate? because earth is formed from cold gases collapsing due to gravity because the matter in the nebula that formed earth was spinning because earth forms more than 99% of the mass of the solar system because the hydrogen atoms inside the nebula fused to form helium
