Question

Correct answer I will mark as brainleist
{we know electron are negative charged and protons are postive charged}
{and we know also that postive and negative charged always attract each other}
so why they don't attract in an atom

Answer 1

the reason for this is that the centripetal force dosent allow it also as it is known that the direction  of it along the tangent so

Answer 2

The electrons are present in orbitals . In that orbitals there are fixed boundaries for electrons to move . So they cannot leave orbitals for such a less charge of proton force.
Also the inter electron forces also helps to attain stability in the orbit.
