Resumo de Recurso

Questão 1

Questão
Which of the following did Democritus NOT believe about atoms?
Responda
  • They came in different shapes and sizes
  • They are divisible
  • Everything is made up of atoms and empty space
  • None of the above

Questão 2

Questão
Which scientist was the first to propose that atoms combined in specific proportions to create compounds?
Responda
  • Rutherford
  • Dalton
  • Thomson
  • Bohr

Questão 3

Questão
Thomson's concept of the atom was flawed because it didn't account for isotopes.
Responda
  • True
  • False

Questão 4

Questão
Thomson's '[blank_start]chocolate chip cookie[blank_end]' model of the atom was conceptualized based on the results of the [blank_start]cathode ray[blank_end] experiment. The experiment proved that atoms were [blank_start]repulsed[blank_end] by the negative part of a magnetic field. Based on these observations, Thomson realized that [blank_start]electrons[blank_end] existed inside the atom.
Responda
  • chocolate chip cookie
  • beehive
  • cathode ray
  • gold foil
  • repulsed
  • attracted
  • electrons
  • protons
  • neutrons
  • sub-atomic particles

Questão 5

Questão
When the gold foil experiment was performed, 1/10,000 alpha particles were deflected.
Responda
  • True
  • False

Questão 6

Questão
Which restriction(s) applied to Rutherford's model of the atom?
Responda
  • Did not account for isotopes
  • If model was accurate, electrons should lose energy and collapse into themselves, causing the entire atom to collapse
  • Did not account for the behaviour of certain gasses
  • Model only works for atoms with one electron

Questão 7

Questão
The [blank_start]colour[blank_end] of light emitted by an atom is dependent on the [blank_start]size[blank_end] of the quantum jumps that the atom's [blank_start]electrons[blank_end] make.
Responda
  • colour
  • size
  • electrons

Questão 8

Questão
Who proposed the Uncertainty Principle?
Responda
  • Heisenberg
  • Bohr
  • de Broglie
  • Schrodinger

Questão 9

Questão
The Uncertainty Principle states that we cannot know both the [blank_start]position[blank_end] and [blank_start]momentum[blank_end] of a particle at a given time.
Responda
  • position
  • energy
  • momentum
  • shape

Questão 10

Questão
What idea about the structure of an atom did Louis de Broglie propose?
Responda
  • He came up with the quantum mechanical model of the atom
  • He created equations to indicate the probable location of an atom
  • He hypothesized that the dual-wave properties of light also apply to matter
  • None of the above

Questão 11

Questão
6.626 x 10^-34 is [blank_start]Planck[blank_end]'s constant
Responda
  • Planck

Questão 12

Questão
Why is the electron orbital diagram incorrect?
Responda
  • It violates Hund's Rule
  • It violates the Aufbau Principle
  • It violates the Pauli Exclusion Principle
  • The diagram is not incorrect

Questão 13

Questão
Why is the electron orbital diagram incorrect?
Responda
  • It violates the Aufbau Principle
  • It violates the Pauli Exclusion Principle
  • It violates Hund's Rule
  • The diagram is not incorrect

Questão 14

Questão
Why is the electron orbital diagram incorrect?
Responda
  • It violates the Aufbau Principle
  • It violates the Pauli Exclusion Principle
  • It violates Hund's Rule
  • The diagram is not incorrect

Questão 15

Questão
Why is the electron orbital diagram incorrect?
Responda
  • It violates the Aufbau Principle
  • It violates the Pauli Exclusion Principle
  • It violates Hund's Rule
  • The diagram is not incorrect

Questão 16

Questão
The l value of a 4f electron is 3.
Responda
  • True
  • False

Questão 17

Questão
All four quantum numbers for the 2nd electron in a 3p orbital are:
Responda
  • n = 3, l = 2, ml = 0, ms = 1/2
  • n = 3, l = 2, ml = 0, ms = -1/2
  • n = 3, l = 1, ml = 0, ms = 1/2
  • n = 3, l = 1, ml = 0, ms = -1/2

Questão 18

Questão
Hydrogen bonding is the strongest type of intramolecular bond
Responda
  • True
  • False

Questão 19

Questão
Which type of intermolecular bonding is the weakest?
Responda
  • Dipole-Dipole
  • London Forces
  • Hydrogen Bonding
  • None of the above

Questão
Wavelength and frequency are [blank_start]inversely[blank_end] related, wavelength and energy are [blank_start]inversely[blank_end] related, and energy and frequency are [blank_start]directly[blank_end] related.
Responda
