A nucleus consists of nucleons comprising of protons and neutrons. A proton has a positive charge equal to _ and has a mass of _.
Correct answer: B. 1.6.x 10-19C; 1.673 x 10^-27kg
- A. 2.6 x 10^-19 C; 36. x 10-28 kg
- B. 1.6.x 10-19C; 1.673 x 10^-27kg
- C. 3.6 x 10^-19C; 2.111 x 10^-27kg
- D. 4.6 x 10^-19 C ; 9.111 x 10^-27kg
- E. 5.6 x 10^-19C; 8.111 x 10^-27kg
Explanation
The charge of a proton is indeed 1.6 x 1019 Coulombs (C). This value represents the fundamental unit of positive charge carried by a proton. The mass of a proton is approximately 1.673 x 1027 kilograms (kg). This value represents the mass of a proton, which is approximately 1,836 times greater than the mass of an electron.

About Nuclear Physics
Atomic nuclei contain protons and neutrons, with nuclear size, mass defect and binding energy describing their stability. The work covers alpha, beta and gamma decay, decay equations, half-life and decay rate, along with radiation safety and medical applications such as imaging, radiotherapy and tracers.
