Ch 5 – EM – (b) Current of Electricity
... • Charge is measured in units called coulombs (C). The charge on an electron is -1.6 x 10⁻¹⁹ C. • Normally atoms have equal number of positive and negative charges, so that their overall charge is zero. • For some atoms, it is relatively easy to remove an electron, leaving an atom with an unbalanced ...
