For other elements the electrons are less free, in that they still experience the potential of the metal atoms, sometimes quite strongly.

Much research went into the study of clustering of metal atoms.

The mass of an alkali metal atom also increases going down the group.

"The metal atoms within a wire may start moving if current is run in one direction," she said.

It must have been using the sail to gather metal atoms from the star's rich wind when the storm struck.

Each metal atom in a wire donates one electron to the current.

When the electrons are stolen or added, the metal atoms become charged and will dissolve in the water.

The M site is placed at the bottom of the hydrophobic pocket with several metal atoms.

The identity of the metal atoms is not known with absolute certainty.

By the time that happens, the metal atoms will be emitting quite a brilliant glow.
