Hund's rule is used for what?

A. degenerate orbitals में electron filling / Electron filling in degenerate orbitals

Step 1: This is about electron filling rules. Step 2: Hund's rule says electrons occupy equal energy orbitals singly before pairing. Step 3: Exam tip: use the bus seat analogy, one electron in each empty orbital first.

Step 1: यह electron filling rules का प्रश्न है। Step 2: Hund's rule के अनुसार equal energy orbitals में पहले electrons single-single भरते हैं। Step 3: परीक्षा टिप: bus seats analogy याद रखें, पहले खाली seats पर एक-एक electron।
