Atomic Structure
State the 3 subatomic particles that make up an atom.
Protons, Neutrons and Electrons
State what 2, 8, 8, 2 rules refers to.
Two electrons in shell #1
Eight electrons in shell #2
Eight electrons in shell #3
Two electrons in shell #4
Describe why the atomic mass changes in isotopes of the same element.
Because the number of neutrons change.
State the definition of unstable nuclei
isotopes with excess protons or neutrons.
State what colour Miss Stirling's phone case is.
Purple
Identify the number of protons and electrons for a Carbon atom.
6
State the names of the two types of ions.
Cations and Anions.
Identify the atomic mass and atomic number for Carbon-14.
Atomic Mass - 14
Atomic Number - 6
Identify the 2 things emitted through radiation.
Electromagnetic waves
Subatomic particles
State the name of the school Miss Stirling worked at before coming to Aveley
Warnbro
Identify the number of neutrons in a Nitrogen atom.
14 - 7 = 7
Describe how ions are formed.
When atoms donate or accept electrons.
Identify how many more neutrons Nitrogen-15 has compared to Nitrogen-14.
1 more neutron.
Describe what half-life is.
Time taken for half the nuclei in a radioisotope to decay
State the name of one of Miss Stirling's brothers.
Alex, Ben or Michael
Draw a Bohr diagram of Sulfur.
Nucleus - P:16, N: 16
Electron Shells - 3 shells
S: 2, 8, 6
Draw a Bohr diagram for Oxygen -2.
Nucleus - P = 8, N = 8
Electron shells - 2
Electrons - 2, 8
Draw a Bohr diagram for Lithium-8.
Electron Shells - 2, with 3 electrons.
P - 3
N - 5
If a radioisotope's half life is 8 years, then how many half-lives have been after 16 years.
2
State the name of Miss Stirling's dog.
Finn
Draw a Bohr diagram of Sodium
Nucleus - P:11, N: 12
Electron Shells - 3 shells
S: 2, 8, 1
Describe why Group 18 elements don't form atoms.
Group 18 elements have a full outer shell, this means they are already stable and therefore don't need to donate or accept electrons to achieve stability.
Draw a Bohr diagram for oxygen 18
Electron shells - 2, electrons - 2, 6 (8)
P - 8
N - 10
5
Identify how many years Miss Stirling has been a teacher.
