They are fundamental particles.
The moving electrons in an electromagnet come from the flow of electric current through a wire or coil.
No. But beta particles can either be electrons, or anti-electrons.
from everywhere
Moving electrons in an electromagnet come from the flow of electric current through a wire or coil of wire.
The electrons in a covalent bond come from the outer energy levels of the atoms involved. Each atom contributes one or more electrons to be shared between them. This sharing creates a stable electron configuration for both atoms.
If you come in contact with high speed electrons from an electron gun, you will get an electrical shock.
When making an electromagnet, the moving electrons come from the flow of electric current through a wire or coil of wire.
If you are filling in the electrons it will be in the 4d orbital. If you are removing electrons the first to come out is in the 5s electrons since transition metals lose 's' electrons before 'd' electrons
Electrons
The electrons used in the electron transport chain come from the breakdown of molecules like glucose during cellular respiration.
Charges come from the imbalance of protons and electrons in an atom. Protons have a positive charge, electrons have a negative charge, and when these charges are not balanced in an atom, it becomes charged. This imbalance can result from the gain or loss of electrons in a process known as ionization.
The electrons moving along the inner membrane of the mitochondria come from molecules such as NADH and FADH2, which are generated during the citric acid cycle and glycolysis. These molecules donate their electrons to the electron transport chain to drive the production of ATP through oxidative phosphorylation.
