Excess Electrons Calculator
Find the number of excess electrons for a given charge.
Charge is quantized; this counts how many electrons make up a given charge.
The math behind it
N = |Q| ÷ e, where e = 1.602 × 10⁻¹⁹ C is the elementary charge.
Worked example
−1 nC → about 6.24 × 10⁹ electrons.
FAQ
Can charge be any value?
No — it's always a whole-number multiple of the elementary charge.
