it should gain one electron

A single electron contains no atoms; atoms contain electrons instead.
Atoms that have lost or gained electron(s) are called ions. If they are positively charged (lost an electron(s)), they are called cations. If they are negatively charged (gained an electron(s), they are called anions.
An electron beam is shot at the Cu atoms, from an electron gun, this knocks out electrons meaning the overall charge of the atom becomes positive as negative electrons have been lost.
Atoms are defined by the number of positively charged protons, not negatively charged electrons. Atoms that lose or gain an electron are called Ions. Anion - gained an electron, negative charge Cation - lost an electron, positive charge

If the chemical bond is ionic, an electron is gained or lost. If it is covalent, the electron is shared equally; if it is polar covalent, the electron is shared unequally. If the bond is intermolecular, no parts of the atom are actually shared, gained, or lost; the atom itself is simply attracted to other atoms.
it should gain one electron
The electrons surrounding the nucleus of an atom are in fixed 'layers' - with a defined number of electrons in each 'shell'. Stable atoms have a fixed number of electrons in their outer shell. When two atoms combine (to form a molecule) one electron is 'discarded' and the two atoms share a common electron to keep the molecule stable. The electron that's 'discarded' is said to be 'lost'. The electrons are still present - just 'free-floating'. When two atoms split, they 'grab' a free-floating electron to stabilise the molecule again. This electron is said to have been 'gained'.
The theory is that some electrons are only weakly held to their atoms (they are in an outer electron shell). Some other atoms have an outer electron shell that is not fully complete and is able to attract electrons away from atoms that have loosely-held ones. Both these atoms then become ions, one charged positvely (having lost an electron) and some negatively (having gained one).

An atom that has lost or gained electrons is known generally as an ion. More specifically, an atom that has lost electrons becomes a cation. It has a positive charge. An atom that has gained electrons becomes an anion. An anion has a negative charge.
