Morphology
The meaning is directly compositional: 'negative' (less than zero / negatively charged) modifies 'charge' (an excess or deficiency of electrons), so the phrase denotes a charge with an excess of electrons. This is a standard, literal technical noun phrase with the same logic in many languages, so a B1 learner who knows both words will readily infer the meaning.
Etymology
The term negative charge uses the words negative (meaning 'minus') and charge (a word for stored electricity). It describes objects that have more tiny particles called electrons than protons, so they behave as if they carry extra 'minus' electricity, and that is why we say they have a negative charge.
