Negatively charged subatomic particle

A very small particle with a negative electric charge.

సాధారణ తప్పు:
Learners often confuse electrons (negative) with protons (positive) or neutrons (no charge).
విరుద్ధపదాలు
positron (An antiparticle with the same mass as an electron but a positive charge.)

Electron in an atom or molecule

An electron that is part of an atom or molecule.

వాడుక నమూనా: an electron in [an atom/molecule]; valence electrons
సాధారణ తప్పు:
Learners may think electrons move in fixed circular paths; in modern descriptions they occupy orbitals (regions of probability).

ఉదాహరణలు
  • Sodium has one valence electron that it readily loses.
  • The two atoms share a pair of electrons in a covalent bond.
  • Removing an electron from the atom requires energy.
అభ్యాసకుల ఉదాహరణలు
  • This atom has two electrons in its outer shell.

Charge carrier in electric current

A moving electron that carries electricity in a wire or device.

వాడుక నమూనా: electrons flow through [a wire/material]; electron flow
సాధారణ తప్పు:
Learners often mix up electron flow (negative to positive) with conventional current direction (positive to negative).
విరుద్ధపదాలు
hole (In semiconductors, a ‘hole’ acts like a positive charge carrier opposite to electrons.)
పదకలయికలు
electron flow |electron drift |electron mobility |conduction electrons |electron current |electron transport |electron conduction |electron-hole pair |electron injection |electron loss
విషయాలు
electronics |physics |technology
ఉదాహరణలు
  • In a metal wire, electrons move through the lattice when a voltage is applied.
  • The device works by controlling the flow of electrons through a thin channel.
  • Higher electron mobility allows faster switching in some semiconductors.
అభ్యాసకుల ఉదాహరణలు
  • Electrons can flow through a wire.
