Potassium has only one electron in its outer shell. To satisfy the octet rule it can either receive 7 electrons or donate 1; the minor is high in energy and thus is not observed in nature. K then donates one electron to become potassium ion (K+) with the electron configuration of argon (Ar).
It depends which 'other atom' it is
Ionic molecules donate electrons.
Donate electrons: oxidation.Accept electrons: reduction.
If a non-metal combines with a metal, then the metal will donate electrons and the non-metal will accept electrons. An ionic bond is the result to form an ionic compound. If the non-metal combines with another non-metal, then both will share the electrons resulting in the formation of a covalent bond between them. The molecule is known as covalent compound.
Fluorine has a stronger attraction to electrons than any other element, so when it bonds to another element that element is going to either donate electrons to the fluorine, or share electrons with fluorine getting the disproportionate share.
A substance that is good at reducing another atom
yes
Hg will not spontaneously donate electrons to copper.
Metals donate electrons by losing electrons and forming positive ions.
Donor atom should donate the electrons to get into a stable state... and sometimes to form an ionic compound..

Sodium is a metal element. There are 11 electrons in a single atom.
