Atomic structure written questions
Write H1 Chemistry answers on atoms, electronic structure and ionisation energies, then check your explanations against marking guidance.
Learning goals
- Identify and describe protons, neutrons and electrons by their relative charges and masses
- Deduce how beams of protons, neutrons and electrons behave in an electric field
- Describe how mass and charge are distributed in an atom
- Work out the numbers of protons, neutrons and electrons in atoms and ions from proton number, nucleon number and charge
- Describe how protons and neutrons make up a nucleus, using proton number and nucleon number
- Distinguish isotopes by their different numbers of neutrons
- Describe the number and relative energies of the s, p and d orbitals for principal quantum numbers 1 to 3, and the 4s and 4p orbitals
- Describe the shapes of s and p orbitals
- Write the electronic configuration of an atom or ion from its proton number and charge
- Explain the factors that affect the ionisation energies of elements
- Deduce electronic configurations from successive ionisation energies
- Relate an element's successive ionisation energies to its position in the Periodic Table
