e following is responsible to rule out the existence of definite paths ortrajectories of electrons.a) Hund's rule of maximum multiplicityb) Aufbau principlec) Heisenberg's uncertainty principled) Pauli's exclusion principle

. All orbitals of a given degenerate (or equal energy) set must be singly occupied before pairing begins in that set is a statement of:1 pointPlanck's theoryHund's rulethe Aufbau principlethe Heisenberg's uncertainty principlethe Bohr theoryPauli's exclusion principle

Hund’s Rule predicts thatGroup of answer choiceselectrons occupy all the orbital of a given subshell singly before pairing begins.electrons must have opposite spins to share an orbital.electrons in an orbital have equal but opposite charges.no two electrons will share the same orbital.

Recall which of the following statements is a part of J.J Thomson's model of the atom. Electrons orbit the nucleus.1Positively charged particles exist within atoms.2There is a positive cloud with electrons scattered through it.

12. Who proposed the probability that electrons can be found incertain locations around the nucleus of an atom?A. Neil’s BohrB. Ernest RutherfordC. Erwin SchrodingerD. Joseph John Thomson

The four quantum numbers of distiguished electron of an atom are as follow begin{tabular}{|l|l|l|l|} hline ( mathrm{n} ) & ( l ) & ( mathrm{~m}_{l} ) & ( mathrm{~m}_{mathrm{s}} ) hline 2 & 1 & 0 & ( +frac{1}{2} ) hline end{tabular} Using the above information answer the following questions. i) How many electrons present in outer most orbit? ii) Write the electron configuration of this element? iii) What is the atomic number of this element? iv) What is the shape of the last electron orbital?
