Question

why specific charge of mass and electron is not negative value specific charge=charge of an electron/mass of electron

Answer 1

Answer:

Since the value of the elementary charge is roughly

1.602 x 10-19 coulombs (C),

then the charge of the electron is -1.602 x 10-19 C. When expressed in atomic units, the elementary charge takes the value of unity; i.e., e = 1.

Thus, the electron's charge can be denoted by -e.
