原げん子し
原子 means 'atom' as a whole, while 原子核 specifically refers to the nucleus at its center.
核かく
核 is a broader term for 'nucleus' or 'core', used in contexts like cell nucleus (細胞核) or nuclear weapons (核兵器). 原子核 is more precise for atomic physics.

Etymology

Compound of 原子 (atom) and 核 (nucleus/core). The kanji 原 means 'origin', 子 means 'child/particle', and 核 means 'core/seed'. The term is a direct translation of the Western scientific concept.
