chapter 4 and 5 test

Quantum -

• radio waves

• A small, discrete unit of energy

• electrons enter orbitals of lower energy first.

A quantum energy is

• farther it is from the nucleus.

• the amount of energy required to move an electron from its present energy level to the next higher one.

• when electrons occupy orbitals of equal energy, olne electron enters each orbital until all the orbital contain one electron with parallel spins.

In general, the higher the electron is on the energy level,

• farther it is from the nucleus.

• olne electron enters each orbital until all the orbital contain one electron with parallel spins.

• lower energy levels lose energy and emit light.

Principal energy levels are

• the major energy levels of electrons.

• the major energy levels of protons.

• the major energy levels of neutrons

In the quantum mechanical model the regions where electrons are likely to be found are called orbitals and are denoted by letters.

• orbitals and denoted by numbers.

• spheres and denoted by letters.

• orbitals and are denoted by letters.

Aufbau principle-

• protons enter orbitals of lower energy first.

• neutrons enter orbitals of lower energy first.

• electrons enter orbitals of lower energy first.

Pauli usion principle - an atomic orbital may describe at

• most 2 electrons.

• most 2 protons

• most 2 neutrons

Hund’s rule-

• when electrons occupy orbitals of unequal energy, three electrons enters each orbital until all the orbital contain one electron with parallel spins.

• when electrons occupy orbitals of equal energy, one electron enters each orbital until all the orbital contain one electron with parallel spins.

• when electrons occupy orbitals of equal energy, two electrons enter each orbital until all the orbital contain two electron with parallel spins.

Radio waves, microwaves, infrared waves, visible light ultraviolet waves, x-rays , and gamma rays are

• included in the protomagnetic spectrum.

• included in the neutromagnetic spectrum.

• included in the electromagnetic spectrum.
