Electron shielding
What Electron shielding means in Chemistry A-Level, as defined for OCR.
Definition of Electron shielding
Check what you remember
Read the wording for your board, then hide it and explain Electron shielding in your own words. Rough notes are fine. This is a self-check, with no mark or grade.
Reference: OCR
Each successive element has more inner shells, so electron shielding increases and further reduces the effective nuclear pull on the incoming electron.
