Answer
  • It is frequently re-examined.
  • It develops over a short duration of time.
  • It has been disproven several times.
  • It is rarely subjected to arguments.

Question 2

Question
Which of the following provides evidence to support Bohr's theory of atomic orbitals?
Answer
  • Plum Pudding Model
  • Gold foil experiment
  • Radiation produced when beryllium is bombarded with alpha particles
  • Spectrum of colors emitted by gas.

Question 3

Question
Which of the following observations indicates that an atom has neutrons?
Answer
  • Some uncharged particles bounce back from gold foil when it is bombarded with alpha particles.
  • Some uncharged particles are scattered by a beryllium atom when it hits gold foil.
  • A radiation with neutral particles is emitted when alpha particles strike beryllium atoms.
  • A radiation which attracts electrons is produced when a beryllium atom is bombarded with alpha particles.

Answer
  • Only particle C
  • Only particle A
  • Both particles B and C
  • Both particles A and B

Question 5

Question
The table shows the number of charged subatomic particles in an ion. A negatively charged substance is brought near the ion. What will most likely happen and why?
Image:
Particles+Table+2 (binary/octet-stream)
Answer
  • The ion will repel the substance because it has more protons than electrons.
  • The ion will repel the substance because it has more electrons than protons.
  • The ion will attract the substance because it has more protons than electrons.
  • The ion will attract the substance because it has more electrons than protons.

Question 6

Question
What is the highest point of a wave called?
Answer
  • Trough
  • Frequency
  • Crest
  • Amplitude

Question 7

Question
A football player experiences acute pain in his knee. Which of the following methods can a doctor use to diagnose the reason for the pain?
Answer
  • Use x-ray radiation to see if there are any fractured bones
  • Use radio waves emitted by radioactive substances to look at bones
  • Use infrared radiation from warm objects to look inside the knees
  • Use radiations emitted by very hot objects to penetrate the skin and bones.

Question 8

Question
What term is used to describe the lowest energy level of a particle?
Answer
  • Excited state
  • Ground state
  • Photon
  • Emission spectrum

Question 9

Question
An electron moved from a lower energy level to a higher energy level. What most likely happened during the transition?
Answer
  • A random amount of light was released.
  • A random amount of light was absorbed.
  • A fixed amount of energy was released.
  • A fixed amount of energy was absorbed.

Question 10

Question
This is represented by the letter n. n is the first number that describes the probable position of every electron and can be any whole number from 1 to 7.
Answer
  • Principle atomic number
  • Principle quantum number
  • Principle electron number
  • Principle ionic number

Image:
Electron+Comparison (binary/octet-stream)
Answer
  • Both are highly reactive.
  • Both are unreactive.
  • A is unreactive and D is reactive.
  • D is unreactive and A is reactive.

Question 12

Question
A substance is present in the gaseous state at room temperature. Which of the following best explains the probable position of the substance in the periodic table?
Answer
  • It is between groups 1 to 12 because it is a metal.
  • It is between groups 1 to 12 because it is a nonmetal.
  • It is between groups 13 to 18 because it is a metal.
  • It is between groups 13 to 18 because it is a nonmetal.

Question 13

Question
Which of the following groups of elements are likely to have substances that are both metallic and non-metallic properties?
Answer
  • Group 18
  • Lanthanides
  • Group 14
  • Actinides

Question 14

Question
This group of elements is silvery and shiny. They are extremely reactive because they lose their outer electron easily to form a cation. Because of this, they cannot exist alone in nature.
Answer
  • Alkaline metals
  • Alkali metals
  • Transition metals
  • Metalloids

Question 15

Question
Which of the following properties increase down a column in the periodic table?
Answer
  • Ionic radii
  • Effective nuclear charge
  • Number of valence shell electrons
  • Ionization energy

Question 16

Question
Which of the following correctly compares the radii of Cl and Cl−?
Answer
  • Cl has a smaller radius than Cl− because Cl has an expanded electron cloud
  • Cl has a larger radius than Cl− because Cl− has an additional energy shell.
  • Cl has a larger radius than Cl− because Cl has an additional energy shell.
  • Cl has a smaller radius than Cl− because Cl− has an expanded electron cloud.

Question 17

Question
Which of the following explains how Albert Einstein tried to influence the discovery of the energy equation?
Answer
  • He supported the use of radioactive elements for medical diagnostic purposes.
  • He opposed the use of nuclear fusion during the Manhattan project.
  • He recommended applying the principles of nuclear fission to defend against enemies.
  • He recommended uncontrolled fusion for medical testing and treatment.

Question 18

Question
