Select the set of quantum numbers that is not permitted. n = 2, l = 1, ml = 1, ms = +½

n = 1, l = 0, ml = 0, ms = –½

n = 4, l = 3, ml = 3, ms = –½

n = 3, l = 3, ml = 2, ms = +½

n = 3, l = 0, ml = 1, ms = +½

Calculate the mass of silver needed to react with chlorine to produce 126g if silver chloride?

Identify one disadvantage to each of the following models of electron configuration: -dot structures -arrow and line diagrams -written electron configurations type in your answer below. (answer) -dot structures do not show the distribution of electrons in orbitals and take up a lot of space. -arrow and line diagrams take up a lot of space and make it difficult to count electrons. -written configurations make it easy to lose count of electrons and do not show the distribution of electrons in orbitals.
