Practise defining an atomic orbital as a region holding up to two opposite-spin electrons and explain paired arrows using Edexcel IAL Chemistry evidence.
This question is about the structure of atoms.
State what is meant by the term orbital.
A statement that makes reference to the following points: - a region within an atom - can hold (up to) two electrons (with opposing spins) or where there is a high probability of finding an electron (1) Allow A region around the nucleus Allow area/place/space for region Ignore path/track/orbiting Do not award in the nucleus Allow a percentage between 90 and 95 Allow a greater chance of finding / most likely to find Do not award just likely Marks are standalone
