Question

1 The mass of an electron is about times that of proton. 2000. State whether the statement is True (or) False. And Justify it.

Answer 1

$\textbf{False}$

Mass of a proton is 1838 times than that if an electron.

Relative mass of proton is equal to 1.005757 amu which is take to be 1 amu.

Answer 2

Dear Student,

● Given statement -

The mass of an electron is about 1/2000 times that of proton.

◆ Answer -

True

● Extra information -

• Three main sub-atomic particles of an atom are proton, neutron and electron.
• Protons are positively charged, electrons are negatively charged and neutrons are uncharged.
• Each atom contains protons & neutrons in the nucleus and electrons revolving around nucleus in specific orbits.
• Protons give positive charge to the nucleus. Electrons give negatively charge to the periphery.
• Mass of proton and neutron is approximately same.
• On the other hand, mass of electron is 1/2000 times of proton.

Thanks dear. Hope this helps you...
