Which subatomic particle have an approximate mass of 1.
Which subatomic particle have an approximate mass of 1.
The correct option is B Proton and neutron
The explanation for the correct option:
An atom is the smallest unit of matter that encompasses all the chemical properties of the element. An atom is composed of 3 subatomic particles known as electron, proton, and neutron which are responsible for the entire mass and charge of the atom.
(B) Proton and neutron:
- The mass of protons and neutrons are nearly the same that is, about grams, which scientists define as one amu or atomic mass unit or one Dalton.
- The mass of all the subatomic particles is given in the table below.
Subatomic particle Relative mass Relative charge Location in the atom Proton 1 u +1 In the nucleus Neutron 1 u 0 In the nucleus Electron -1 Outside the nucleus
The explanation for the incorrect option:
(A) Electron and proton: The Mass of electron and proton is not the same. The mass of a proton is 1840 times higher than the mass of the electron.
(C) Neutron and electron: The Mass of Neutron and proton is not the same. The mass of a neutron is approximately 1840 times higher than the mass of electrons.
(D) None of them
Thus, Option (B) is correct, i.e., Proton and neutron subatomic particles have an approximate mass of 1.
