To determine the distance, an electron is from the nucleus in a hydrogen atom. We first need to know what energy level the electron will be in when it has the energy that has provided negative 8.72 times 10 to the negative 20 joules. We'Ll use the red burg equation, where e is equal to the red burg, constant 2.178 times 10 to the negative 18 joules multiplied by 1 over the energy level. Well, if we know the energy we know the constant, then we can solve for and set an ends up being equal to 5 point. Then we can use the second equation where the radius or the distance, the electron is from. The nucleus is equal to n squared multiplied by the bore radius, so it will be 5 squared multiplied by the boer radius of 5.29 times 10 to the negative 11 meters which, when converted to angstroms by dividing by 1 times 10 to the negative 10, gives us .2, .529 angstroms, so .529 angstroms multiplied by 25. It being in the fifth energy level gives us the electron at 13.2 angstroms from the nucleus.
