Sort by:

Electron As momentum(P) = $$\sqrt{2*M*E}$$ Where M = mass of particle and E is the kinetic energy of the particle. As E is same for the particles, Hence Momentum is directly proportional to $$\sqrt{M}$$. As electron ha minimum mass among them, so momentum of electron is minimum.

why electron cloud make atom more stable?

it's proton.. cuz' if according atom theory.. electron move around the element.. and proton stay inside the nucleus.. therefore.. proton.. can't be taken out so easily... if u're able to pluck out the proton.. means u're doing nuclear fision ady~
