It has to do with entropy. The law of entropy states that the universe tends toward having the lowest possible energy at every point. Two oppositely charged particles' magnetic fields cancel out, so, to follow this tendency, they attract each other to have more of their fields overlapping, and so, reducing the energy at each point. Two electrons are samely charged, and so, when their fields overlap the energy of each field will add together. To keep with entropy, the particles repel so that less of their fields overlap, making the energy at each point as low as possible.

Why electron doesn't replel in an orbit?
Electron doesn't repel in an orbit however they are same charged particle, but same charged particles always repel. This is due Meson's theory of charged particles, he says electrons doesn't repel because they have one orbital different and another different.
How many valence electrons are in aluminum?
Alkaline earth metals are group 2 elements and have 2 valence electrons.
How many valence electrons would be found in an atom of hellium?
Helium has 2 valence electrons, and it's the only noble gas that doesn't have 8 valence electrons.
What dry chemical is used to repel heat?
H2O (water) is used to repel heat.
What is the symbol for 2 electrons and 2 protons?
Number protons equal to atomic number. So the element is Helium
Would 2 protons attract or repel each other?
"Opposites attract". So two electrons repel each other.
What is the subatomic particles that electrons repel?
1) what is electron? 2) what is matter? 3) structure of atom?
Do electrons repel electrons?
Yes.
What would repel an electrons?
Another electron. Or anything else that has a negative charge.
Do electrons need energy to repel each other?
They possess negative charges and in the universe anything having same charge would repel eachother.
What will two electrons do?
Repel each other
Do electrons repel one another?
yes. all particles with like charges repel each other.
Do electrons repel each other within the same atom?
no
What would happen if you placed two electrons near each other in free space?
They would repel each other as they are both negativly charged.
Why do sets of electrons repel each other?
they carry same charge thus repel as opposites attract each other
What will an electron do if placed near another electron?
The two electrons will repel one another, through the electrostatic force.
Why do electrons spread out as much as possible in an atom?
The negative charges of their electrons repel each other.
