Question 12

provides a comprehensive understanding of electron behavior

Answer 12

quantum mechanics

Question 13

electron exist as a probable wave-like pattern around nucleus, not in a specific orbit. It explains why electrons act like particles and waves, and is the foundation of our understanding of atomic structures and widely used in modern physics.
