357972 Assume that each of copper atoms has one free electron. Estimate the number of free electrons in 1 \(mg\) of copper. Given that atomic weight of copper \( = 63.5g\) and Avogadro number is \(6.023 \times {10^{23}}\).What is the charge possessed by these free electrons?
357975
I.
The charge \(q\) on a body is always given by \(q = ne\),where n is any integer, positive or negative
II.
By convention, the charge on an electron is taken to be negative.
III.
The fact that electric charge is always an integral multiple of e is termed as quantisation of charge
IV.
The quantisation of charge was experimentally demonstrated by Pascal.
Which of the statements is incorrect?
