GCSE Chemistry · key term
The occupied electron shell furthest from an atom's nucleus.
Used by AQA, Edexcel and OCR
Specification 4.1.1.7 · Paper 1
The occupied energy level furthest from the nucleus.
Specification 1.19, 1.20, 1.21, 6.14 · Paper 1, Paper 2
The electron shell furthest from the nucleus that contains electrons.
The occupied electron shell furthest from the nucleus.
The occupied electron shell furthest from an atom's nucleus; its electrons are involved in chemical reactions.
Specification C2.2c, C2.2h, C4.1b · Paper 1 (Foundation), Paper 2 (Foundation), Paper 3 (Higher), Paper 4 (Higher)
The highest occupied energy level in an atom, containing the electrons used to identify its main group.
Revise: Electronic Structure and PeriodicityA new period begins when an electron first enters a new outer shell.
The highest occupied electron energy level in an atom.
The highest occupied electron shell of an atom; its electrons are principally involved in chemical reactions and bonding.
Paper 1 (Foundation), Paper 2 (Foundation), Paper 3 (Higher), Paper 4 (Higher)
The occupied electron shell furthest from the nucleus.
Revise: Periodic Table arrangementElements in the same group have the same number of electrons in their outer shells, although the number of occupied shells increases down the group.
The highest occupied electron shell of an atom.
The outermost occupied electron shell of an atom.
The occupied electron shell furthest from an atom's nucleus; its electrons are chiefly involved in chemical reactions.
An atom or ion's highest occupied electron shell.
For Edexcel group numbers 1–7, the group number equals the number of outer-shell electrons. Treat group 0 separately: its atoms have a full outer shell.
Read an electronic configuration from the nucleus outwards. In 2.8.7, the final 7 is the number of electrons in the outer shell.
Check that electrons have been conserved: every electron lost by one atom must appear in the outer shell of the other atom.
