Hi. Do there exits equipment that can read the elementary charge of atom? Or do we only know there charge by calculation?
And the same question about there mass
And the same question about there mass

An atom does not have an elementary charge associated with it.Ankhen said:Hi. Do there exits equipment that can read the elementary charge of atom? Or do we only know there charge by calculation?

Nope, but thanksanorlunda said:Do you also know about mass spectometers?
Elementary charge, also known as the elementary charge of an electron, is the smallest unit of electric charge. It is represented by the symbol "e" and has a value of approximately 1.602 x 10^-19 Coulombs.
Elementary charge is typically calculated using the formula Q = n x e, where Q is the total charge and n is the number of elementary charges. For example, if there are 5 elementary charges present, the total charge would be 5 x 1.602 x 10^-19 Coulombs.
Elementary charge is significant because it is the fundamental unit of electric charge and is present in all matter. It helps determine the properties and behavior of atoms and molecules, and plays a crucial role in many electrical and chemical processes.
Knowing about elementary charge is important for understanding the basic principles of electricity and electromagnetism. It also has practical applications in fields such as electronics, chemistry, and physics.
Yes, elementary charge can be measured experimentally using a device called an electron charge balance. This device uses the repulsive force between two charged metal plates to measure the charge of a single electron. Other methods, such as the Millikan oil drop experiment, can also be used to measure elementary charge.
