Question

why mass and weight both are same in case of electron,proton and neutron​

Answer 1

Explanation:

Number of protons=6, the mass of protons= 6 atm amu

Number of neutrons=8, the mass of neutrons= 8 amu

mass of

6

14

C =6+8=14amu

When the mass of neutrons is halved and the mass of protons is doubled, the mass of

6

14

C becomes

2

8

+6×2=16amu

Percentage by which the mass has increased=

14×100

(16−14)

=14.28%

Hence, mass of

6

14

C is=14.28 more

Answer 2

Explanation:

Protons and neutrons have approximately the same mass, about 1.67 × 10-24 grams, which scientists define as one atomic mass unit (amu) or one Dalton. Each electron has a negative charge (-1) equal to the positive charge of a proton (+1). Neutrons are uncharged particles found within the nucleus.Electrons are a type of subatomic particle with a negative charge. Protons are a type of subatomic particle with a positive charge. ... Protons and neutrons have approximately the same mass, but they are both much more massive than electrons (approximately 2,000 times as massive as an electron).
