Why protons and electrons do not collapse and cancel?

According to Physics opposite charges always attract But in an atom the distance between nucleus and electrons are small then why electrons didnt combined with protons? protons and electrons have opposite charges.But why they didnt combined each other?

Asked Gowtham

KS Samy answers:

“Good question,, both sub-atomic particle have certain mass and energy,, we also know that it,, there is electrons revolved an nucleus and their corresponding energy level,, so that it don’t care their charges.. only arrange respect that energy,,,,

the minimum distance between nucleus and orbital electron have minimum energy, as well as large distance it as more energy.”

A few questions from Yogitha

Yogitha Asked:

  1. Why hot spots are important in harnessing geothermal energy?
  2. Energies that are dependent and non dependent of solar energy?
  3. Compare the energy produced by combustion of an atom of carbon to that of fission of uranium 235?

How atoms are formed? – Neeraj Asks

Neeraj asks: ”We have read that atoms can neither been created nor been destroyed!
I want to know from where atoms came in existence,if they can not been created,also atom contain electron and proton which are negatively and positively charged,i want to know from where these charge came?”

If neutrino travels faster than light?

If neutrinos travel at the speed of light through a vacuum, and rarely interact with matter, how fast do they travel through the nucleus of an atom?

(David Tate asked)

Stringtheory or M theory

Ruben Myrhagen asks”I’ve watched some documentaries about this theory.. from what i could understand ( wich may be little) those tiny strings determine the form of the atom ( i mean if its gas-water or anything) would it be possible to manipulate these vibrating strings to create whatever we want ? like water. gas or energy ? could that be possible ?
i mean they must vibrate at a different rate. not all can be the same could they ? anyways sorry for the stupid question”

Why hole is positive?

Mandeep asks:

 

“As we take a negative charge on the electron,when
electron leave there position,the left particle is
hole,my question is that why we consider hole as a
positive charge ,as a hole is a efficiency of
electron not containing any charge”

 

Answer: Hole is the deficiency (not efficiency) of an electron. It is assigned a positive charge for the sake of convenience of discussing it like a moving charge. When an electron leaves a site, the atom gets ionized and gets a positive charge. This is actually caused by the deficiency of electron. SO, we treat the vacancy of electron like a mobile positive charge. When an electron from the neighbouring atom leaves its ste and another electron fill a hole previously present, we treat it as if the hole has moved from one site to another.
