Who says they don't?
I can't resist the urge to quote "The Hitchhikers Guide" saying space is REALLY big... electrons are tiny compared to the "empty" space in atoms and molecules. There's a low probability that two will intersect.
An electrical current is passed through a cathode, which emits electrons. Next, a high voltage electrical source is powered on the other end of the x-ray tube, which makes the electrons move to the other side. The electrons then collide with an anode, which produces the photons that are needed to produce x-rays.
Close the blinds, fans
So for a typical AC current in a typical lamp cord, the electrons don't actually "flow," instead they vibrate back and forth by about a hundred-thousandth of an inch.

"Which one is better split AC or window AC?""Which one is better split AC or window AC?"
Yes, free electrons can collide with atoms.
Good question! I just wish I knew the answer...
as electrons have same charge ,they repel each other when they come near
When excess electrons collide with other nuclei.
When excess electrons collide with other nuclei.
Yes. And when this occurs, they will collide and annihilate one another.
When a neutron star is formed, protons and electrons are crushed, they collide and become neutrons.
Electrons behave like waves and particles this is characterised by the wave side in the Bohr model and can be diffracted yet it will collide with other particles.
With dc the electrons flow in one direction steadily, but in ac the electrons change directions 50 or 60 times every second. 50 in Europe, 60 in America.
Yes, when they collide with atoms of oxygen and nitrogen in the ionisphere.
A resistor stops the flow of electrons causing them to collide and producing heat
Electron bombardment is a process where neutral atoms are converted to positive ions by bombarding them with electrons. Electrons are knocked off the atoms when fast moving electrons collide with them, forming positive ions.
