| Question | Answer |
|---|---|
| Rutherford's planetary model could not explain the ?? of elements. | chemical properties |
| Bohr proposed that electrons move only in specific ?? around the nucleus. | circular paths |
| Rutherford's model of the atom was known as the ??. | planetary model |
| The quantum mechanical model determines the allowed ? an atom can have. | energies |
| The quantum mechanical model determine how likely it is to be found in ?? around the nucleus. | various locations |
| Each sublevel(suorbital)corresponds to an ?? describing where the electron is likely to be found. | orbital shape |
| The wavelength and frequency of light are ?? to each other. | inversely proportional |
| When an atom absorbs energy, electrons move into ???. | higher energy levels. |
| When electrons drop back to a lower energy level, they ??. | lose energy |
| When electrons lose energy as they move to a lower energy level, they produce ? of different colors. | light |
| The light emitted by electrons as they transition to a lower energy level has a frequency directly proportional to the ?? of the electron. | energy change |
| Classical mechanics adequately describe the motions of bodies much larger than ?. | atoms |
| quantum mechanics describe the motion of subatomic particles and atoms as ?. | waves |
| The fixed energies an electron can have are called ??. | energy levels |
| To move from one energy level to another, the electron must ? or ? just the right amount of energy. | lose or gain |
| In general, the higher an electron is on the energy "ladder", the ? it is from the nucleus. | farther |
| A ? of energy is the amount of energy required to move an electron from one energy level to another energy level. | quantum |
| The higher the energy leveloccupied by an electron, the ?? it takes to move from that energy level to the next higher level | less |
| The modern description of the electrons in atoms, the ???, comes from the mathematical solutions to Schrodinger equation. | quantum mechanical model |
| The probability of finding an electron within a certain volume of space around the nucleus is represented y a ??. | fuzzy cloud |
| Attempts to show probabilities as a fuzzy cloud are usually limited to the volume in which the electron is found ?? of the time | 90 percent |
| An ?? is often thought of as a region of space in which there is a high probability of finding an electron. | atomic orbital |
| The energy levels of electrons in quantum mechanical model are labeled by ???. | principal quantum number |
| For each principal level, there may be several orbitals with ?? and at different ??. | different orbitals energy levels |
| S orbitals are ? shaped. | spherical |
| P orbitals are ? shaped. | dumbbell |
| The three p suborbitals have different ? in space. | orientations |
| The first energy level can hold a maximum of ? electrons. | 2 |
| The second energy level can hold a maximum of ? electrons. | 8 |
| The third energy level can hold a maximum of ? electrons. | 18 |
| The fourth energy level can hold a maximum of ? electrons. | 32 |
| The s orbital has how many suborbitals? | none |
| The p orbitals has how many suborbitals? | 3 |
| The d ortials has how many suborbitals. | 5 |
| The f orbital has how many suborbitals? | 7 |
| ?? is the way in which electrons are arranged in various orbitals around the nuclei of atoms. | electron configuration |
| According to the ??, electrons occupy the orbitals of lowest energy first. | aufbau principle |
| According to the ???. an atomic orbital may describe at most ? electrons. | 2 |
| According to Hund's rule, one electron enter each orbital until each orbital has electrons with the ???. | same spin direction |
| The ? of a wave is the wave's height. | amplitude |
| The ? represents the distance between crests. | wavelength |
| The ? of a wave is the number of wave cycles to pass a given point per unit of time. | frequecy |
| The SI unit for cycles per second is called a ?. | hertz |
| Light consists of ??. | electromagnetic waves |
| All electromagnetic waves move a the ? speed in a vacuum. | same |
| Sunlight consists of light with a continuous range of ? and ?. | wavelength, frequency |
| Band of colored light produced when whit light passes through a prism. | spectrum |
| The frequencies of light emitted by an element separate into discrete lines to give the ??? of the element. | atomic emission spectrum |
| When an electron has its ?? energy, the atom is in its ground state. | lowest possible |
| Light can also be considered to be composed of "packets" of energy know as ?. | photons |
| The ??? states that is impossible to know exactly both the velocity and the position a subatomic particle at the same time. | Heisenberg uncertainty principle |
