Answer:
b. Electrons have a mass of 1 amu
Explanation:
Mass of electron is 0.00055amu.
Charge= - 1.6×10^−19
By definition, the statement b. is false: Electrons haven't a mass of 1 amu. Electrons have a mass of 0.0005 amu.
All atoms are made up of subatomic particles: protons and neutrons, which are part of their nucleus, and electrons, which revolve around them.
Protons are positively charged, neutrons are neutrally charged, and electrons are negatively charged. Protons and neutrons have roughly the same mass, about 1.674×10⁻²⁴ g, which represents 1 atomic mass unit or amu. An electron has a mass of 9.11×10⁻²⁸ g, which represents 0.0005 amu.
So, the atomic nucleus is the small central part of the atom, with a positive electrical charge and in which most of the mass of the atom is concentrated.
In a neutral atom, the number of electrons is equal to the number of protons, and since they have a negative electrical charge, they compensate.
Then, the statement b. is false: Electrons haven't a mass of 1 amu. Electrons have a mass of 0.0005 amu.
