# Is charge transfer from A to B positive or negative?

I see this term pop up a lot -- for instance "charge is transferred from atom A to atom B", but it's never specified whether they're talking about positive or negative charge. I know electrical engineers use that weird background notation for current, but intuitively I would think charge transfer refers to an electron distribution that was originally localized about atom A now being localized about atom B.

Is my guess correct? Google is surprisingly unhelpful, because I can't find an actual authoritative definition, just more usage of the term.

I will show this with a simple $Na^+$ and $Cl^-$ atom configuration. $Na$ atom loses an $e^-$ to become +vely charged. And the $Cl$ atom gains an electron to become -vely charged. Hence the charge on an electron is transferred.
