Answer 1

what is the nature and magnitude of charge on proton

Answer 2

The magnitude of the electric charge on the proton can be seen as an assigned (or a derived) value, notated as +1 where the "+" is the sign on the charge, and "1" the value or magnitude. Electric charge in general reflects quantization - that charge exists in discrete units known as the elementary charge, "e", taken to be the charge on the electron (whose magnitude is the same but sign ("-") is opposite that of the proton). The value in practical units (Coulomb) is about 1.602 x 10^-19 Coulomb. Charge answers to a quantum number which notably is preserved in particle interactions. The nature of charge can be shown in how charged particles such as protons react to the fundamental forces; in the case of electric charge the force of interest would be the electromagnetic force. In this sense its nature could be defined by how it reacts when placed in an electromagnetic field.

Since the proton is a composite particle made of up smaller charged particles which contribute to its overall charge, a full exploration of the nature of electric charge would include an understanding of its three component quarks, which are assigned fractional units of elementary charge, and the sum of the combined fractional charges (+2/3, +2/3, -1/3) equals +1 for the proton.

Note that charge in another sense (color charge, relating to a different fundamental force) is evident for protons; a fuller exploration of the subject is the area of quantum chromodynamics.

Answer 3

A proton carries a positive charge of approximately 1.6 x 10^-19 coulombs, which is considered to be the fundamental unit of positive charge in the universe. This charge is equal in magnitude but opposite in sign to the charge of an electron.

Answer 4

The negative charge of the electron
