2What did Niels Bohr discover ?
- AThe proton
- BOrbitals
- CThe electron

3Rutherford discovered that the atom has a positive nucleus which is surrounded by negative electrons
- AVerdadero
- BFalso
4Electrospray ionisation uses an electron gun to knock of one electron of each atom to turn them into +1 ions
- AVerdadero
- BFalso
5During electron impact ionisation, the sample is [blank_start]vaporised[blank_end] and an [blank_start]electron gun[blank_end] is used to fire [blank_start]high energy electrons[blank_end] at it in order to knock of an electron and turn the atom into a [blank_start]1+ ion[blank_end]
- Avaporised
- Belectron gun
- Chigh energy electrons
- D1+ ion
6In a mass spectrometer, particles are accelerated by [blank_start]an electric field[blank_end] so that they have the same [blank_start]kinetic energy[blank_end]
- Aan electric field
- Bkinetic energy
7The detector in a mass spectrometer detects charged particles as [blank_start]an electric current[blank_end] is produced when a particle hits it
- Aan electric current
8How can you tell which ions have the most neutrons
- AThey will be lighter and travel at higher speeds
- BThey will be lighter and travel at lower speeds
- CThey will be heavier and travel at higher speeds
- DThey will be heavier and travel at lower speeds
9To work out relative atomic mass from a mass spectrometer, [blank_start]multiply[blank_end] the % abundance (y axis) and the isotopic mass (x axis). [blank_start]Add[blank_end] them together and [blank_start]divide[blank_end] by 100 if % were used, if not then [blank_start]divide[blank_end] by them sum of the relative abundance (x axis)
- Amultiply
- Bdivide
- Cadd
- DDivide
- EAdd

12The electronic configuration of Fe3+ is 1s2 2s2 2p6 3s2 3p6 3d5
- AVerdadero
- BFalso
13The definition of first ionisation energy is the energy needed to remove [blank_start]1 electron[blank_end] from each atom in [blank_start]1 mole[blank_end] of gaseous atoms to form 1 mole of [blank_start]gaseous 1+ ions[blank_end]
- A1 electron
- B1 mole
- Cgaseous 1+ ions
14First ionisation energy of Oxygen is
O(l) ----> O+(g) + e-- AVerdadero
- BFalso
15Which factors affect ionisation energies
- ANuclear charge
- BDistance from the nucleus
- CShielding
- DKinetic energy
- ESize of the molecule
- FNumber of electrons
16The more protons there are in the nucleus, the [blank_start]more[blank_end] positively charged the nucleus is and [blank_start]stronger[blank_end] the attraction to the electrons therefore the [blank_start]higher[blank_end] the ionisation energy
- Amore
- Bless
- Cstronger
- Dweaker
- Ehigher
- Flower
17Which of the following is correct
- AThe further away the electron is from the nucleus, the higher the ionisation energy
- BThe further away the electron is from the nucleus, the lower the ionisation energy
18Which of the following statements describing shielding is correct?
- AAs the number of electrons between the outer shell and the nucleus increases, the attraction between the outer electron and the nucleus decreases and therefore the ionisation energy decreases
- BAs the number of electrons between the outer shell and the nucleus decreases, the attraction between the outer electron and the nucleus decreases and therefore the ionisation energy decreases
- CAs the number of electrons between the outer shell and the nucleus increases, the attraction between the outer electron and the nucleus increases and therefore the ionisation energy decreases
- DAs the number of electrons between the outer shell and the nucleus increases, the attraction between the outer electron and the nucleus decreases and therefore the ionisation energy increases
19This is the 3rd ionisation energy of oxygen
O2+(g) -----> O3+(g) + e-- AVerdadero
- BFalso
20Within a shell, successive ionisation energies decrease
- AVerdadero
- BFalso
21Which of the following statements is correct
- AThe first ionisation energy generally increases across a period
- BThe first ionisation energy generally decrease across a period
- CThe first ionisation energy decreases down a group
- DThe first ionisation energy increases down a group
22Electron repulsion causes a [blank_start]decrease[blank_end] in first ionisation energy across a period as the electron is being removed from an orbital that contains [blank_start]2[blank_end] electrons. These electrons [blank_start]repel[blank_end] one another making them [blank_start]easier[blank_end] to remove
