Question

why doesn't an electron fall into the nucleus?????

Answer 1

they depend on the attraction force of nucules

when it is weak they fall electron

or they are strong when they capture electron from other orbit of atom

Answer 2

• electrons revolve around the nucleus in specific path called orbit or shells
•each orbit or shells have specific energy level
• it neither loses nor gains the energy in the specific shell
• if it gains the energy it jumps to the higher energy level.
• and as it loses energy it comes to its original energy level
