Why is charge quantized and unable to exist in fractional or decimal values?

Click For Summary
SUMMARY

Charge quantization dictates that electric charge exists only in integral multiples of the elementary charge (e), which is valued at 1.6 x 10-19 C. The equation q = ne, where n is an integer, confirms that charge cannot take on fractional or decimal values. Despite calculations yielding values like 3.2 x 10-19 C for n = 2, these results are still multiples of the fundamental charge and do not represent fractional charges. Therefore, the principle of quantization ensures that any charge divided by 1.6 x 10-19 will yield an integer.

Homework Statement


Quantisation means charge always exist in integral multiples of magnitude of charge of electron and to put it mathematically we say q = ne, where n is an integer 1,2,3,4 ... -1,-2,-3,... etc. Numerous print and web materials say that charge cannot exist in fraction or decimal, i.e, 2.3e, 4.6e etc. Agreed.

Homework Equations

The Attempt at a Solution


The value of e is 1.6*10^-19 C which itself contradicts the statement that no fraction or decimals is possible while dealing with charge. Also if we take n = 2, we get q = 3.2*10^-19, n =3 means q = 4.8 *10^-19 which are all fractions. Can experts throw light on this aspect? Thanks in advance

It means charge exists in multiples of integers. An easy way to put it is if you divide the value of a charge by 1.6*10^-19, you'll always get an integer and never a fraction.
