In chemistry, an elementary charge is most commonly denoted as an e or a q. According to the formal definition, it is the electric charge that a single proton carries, or it is equal to the magnitude of the electric charge that which a single electron causes.
This means that we do not take into account the sign of the charge, rather the magnitude only. This charge, is referred to as the elementary charge, which is the smallest multiple. Greater charges usually exist as multiple of this elementary charge which is also referred to as e, and it has a fixed elementary value.
The elementarycharge, usually denoted as e or sometimesq, is the electricchargecarried by a single proton, or equivalently, the magnitude of the electricchargecarried by a single electron, which hascharge−e.
