Answers
Answer:
Mass of electron = 9.1 ×10^-31 kg
charge of electron= -1.6×10^-19C
━━━━━━━━━━━━━━━━━━━━━━━━━━
Electron, lightest stable subatomic particle known. It carries a negative charge of 1.602176634 × 10−19 coulomb, which is considered the basic unit of electric charge. The rest mass of the electron is 9.1093837015 × 10−31 kg, which is only 1/1,836the mass of a proton.
Mass, in physics, quantitative measure of inertia, a fundamental property of all matter. ... It is, in effect, the resistance that a body of matter offers to a change in its speed or position upon the application of a force. The greater the mass of a body, the smaller the change produced by an applied force.
The charge of the electron is equivalent to the magnitude of the elementary charge (e) but bearing a negative sign. 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
