The electron numbers in the experiment varied from 10 to 100.

I saw a group of electronic sackbuts at the music store.

The electron pairs in the molecule determine its shape.

There are many electron donors in the chemical reaction.

I love reading electronic books on my tablet.

The electron carriers play a crucial role in the electron transport chain.

The electron shells surround the nucleus of an atom.

The electron densities in the material were measured using a scanning electron microscope.

Electron holes are created when an electron leaves a position in an atom or a crystal lattice.

The electron affinities of these elements vary greatly.
