Flashcards

Electron Charge

The charge of an electron is a fundamental constant, indicating the smallest unit of negative electric charge. It's expressed as -1.6 x 10^-19 Coulombs.

What happens when an atom gains electrons?

When an atom gains electrons, it acquires more negative charges, resulting in an overall negative charge for the atom, making it an anion.

Proton Charge

The charge of a proton is equal in magnitude but opposite in sign to the charge of an electron. It's positive and expressed as +1.6 x 10^-19 Coulombs.

What happens when an atom loses electrons?

If an atom loses electrons, it loses negative charges, resulting in an overall positive charge for the atom, making it a cation.

Charge Conservation

In charging processes, charges are not created or destroyed, they are simply transferred from one body to another. This ensures that the total charge remains constant.
