Question

Abdolute mass eletron​

Answer 1

Answer:

Since the mass of a hydrogen atom is 1 amu (1 atomic mass unit), we can say that the relative mass of an electron is 1/1836 amu. The absolute mass of an electron is, however, 9 x 10-28 gram. The electron in an atom possesses a certain amount of energy to maintain its distance from the oppositely charged nucleus.
