In Nucleus there are Protons which carries + charge. Electrons revolving around the Nucleus carries – charge. On Nucleus there is positive charge So why Electrons doesn’t falls on the Nucleus.
✅ Answers
Answerer 1
They need energy.
Answerer 2
in the atom, protons are the positively charged particles and electrons are the negatively charged particles.both have same magnitude of charge. if you mean to say that opposite charges attract each other, then the fact is that movement of electrons around the nucleus can be compared to the movement of planets around the sun.they move in discrete orbits where there is no loss or gain of energy. particularly, the opposite and equal charges balance each others’ effect and so the atom remains stable and the neutrons do not fall in the nucleus.
Answerer 3
The simple (but inaccurate) answer is that the electron is in orbit so doesn’t fall in – like the moon doesn’t fall into the earth, or the earth doesn’t fall into the sun. This is because the force of attraction is always perpendicular to the velocity of the orbiting object, resulting in orbital motion.
The harder (but more accurate) answer is that quantum mechanics prevents the electron’s energy in an atom from dropping below a certain level call the ground state energy. Because of this, the electron’s probability distribution is such that the average distance of the electron from the nucleus is relatively large.
Answerer 4
Same reason why the moon does not fall on the earth, or the earth into the sun. Because the electron tries to move away from the nucleus (not radially outwards) at a very high speed.
Answerer 5
because electrons move with a very high speed and the move away from the nucleus before they can fall into the nucleus. you will learn about this in higher classes
