Question

How does the mass of an electron compared to the mass of an atom help us understand that electron’s are tiny pieces of atoms

Answer 1

Answer:mass of an electron is 1/1840 mass of a proton

Step-by-step explanation:

Since the mass of an electron is 1/1840 the mass of a proton (and neutron) and an atom contains both protons and electrons in equal number together with neutron, the total mass of the electrons in and atom is much less that the total mass of the protons and neutrons.
