Description

The second quiz for unit 1/2 chemistry. This is to gain an understanding on how to use the periodic table based on the structure of the atom.

Resource summary

Question 1

Question
Where is majority of the mass of an atom?
Answer
  • The cloud
  • The nucleus
  • The electron
  • The mitochondria

Question 2

Question
The name of Rutherford's experiment was called the [blank_start]Gold Foil[blank_end] experiment which provided evidence for the existence of the [blank_start]nucleus[blank_end] of the atom.
Answer
  • Gold Foil
  • Silver Foil
  • Scotch Tape
  • Electron Gun
  • electron
  • proton
  • nucleus
  • atom
  • shape
  • neutron

Question 3

Question
Label the picture with the appropriate terms. Each dot only needs one term.
Answer
  • Atomic mass
  • Atomic address
  • Atomic radioactivity
  • Atomic Number
  • Just a pointless number
  • Abundance
  • Chemical symbol
  • Algebra representing the element
  • Represents an ion

Question 4

Question
A proton has a mass of 1. So Hydrogen, being the first element, has a mass of 1. Chemists hypothesised, that the proton (being almost 2000 times heavier than the electron) contributed all the mass of an atom. As such, an element like helium, which has 2 protons, would be twice as heavy as a hydrogen atom. However, it was found that it was 4 times as heavy compared to hydrogen. Why is this?
Answer
  • The presence of dark energy.
  • The existence of an uncharged subatomic particle known as a neutron.
  • The mass of electrons was actually incorrect, it is the same as a proton.
  • The helium sample in experiments may have been dirty, altering the results.

Question 5

Question
Round numbers to the nearest whole number. (eg 1.5 -> 2) Magnesium has an atomic number of [blank_start]12[blank_end]. This means it has [blank_start]12[blank_end] protons. Furthermore, Magnesium is known to have an atomic mass of [blank_start]24[blank_end]. Therefore, it must have [blank_start]12[blank_end] neutrons. In order for Magnesium to have an ionic charge of +1, it must have [blank_start]11[blank_end] electrons orbiting.
Answer
  • 12
  • 12
  • 12
  • 24
  • 11

Question 6

Question
An isotope is: (may be more than one correct)
Answer
  • An atom
  • Depends on number of electrons
  • Depends on number of protons
  • Depends on number of neutrons
  • Makes atoms safe
  • Makes atoms unstable
  • Can cause radioactivity

Question 7

Question
Uranium has an atomic number of [blank_start]92[blank_end]. It has [blank_start]92[blank_end] protons, but has [blank_start]146[blank_end] neutrons.
Answer
  • 92
  • 92
  • 146
