Question

Mass of electron is;
1.6 x 10-24 g ii.
9. X 10-27 g iv.
9 x 10-28g
1.66 x 10-24 g​

Answer 1

Answer:

An electron is a tiny particle with a mass of 9.108×10

−28

g and a negative charge. All neutral atoms contain electrons. The mass of a proton is 1.6726×10

−24

g, or about 1836 times the mass of an electron. The proton carries a positive electrical charge, that is equal in magnitude to the charge of the electron but opposite in sign. Mass of a neutron is 1.675×10

−24

g. It is very close to that of the proton. A neutron carries no charge.

Answer 2

Answer:

B. 9. X 10-27 g

Mass in kg is 9. X 10-³¹ kg
