CHXI02:STRUCTURE OF ATOM
307628
The charge on positron is equal to the charge on
1 proton
2 electron
3 \({\rm{\alpha - }}\) particle
4 neutron
Explanation:
Positron is positively charged subatomic particle.
CHXI02:STRUCTURE OF ATOM
307629
Which is correct statement about proton?
1 Proton is nucleus of deuterium
2 Proton is \({\rm{\alpha }}\) - particle
3 Proton is ionized hydrogen molecule
4 Proton is ionized hydrogen atom
Explanation:
Proton is the nucleus of H-atom (H-atom devoid of it’s electron)

Let mass of electron is half, mass of proton is two times and mass of neutron is three fourth of original. The new atomic wt. of \({{\rm{O}}^{{\rm{16}}}}\) atom
1 Increases by 37.5%
2 Remains constant
3 Increases by 12.5%
4 Decreases by 25%
Explanation:
We can neglect the mass of electron. In \({{\rm{O}}^{{\rm{16}}}}\) atom, total 8 protons and 8 neutrons are present. The mass of proton has proton increased two times, so it’s contribution becomes 16 and neutronmass has changed to \({\rm{3/}}{{\rm{4}}^{{\rm{th}}}}\) of initial mass, so it’s contribution becomes 6. Total mass becomes \({\rm{ = }}\frac{{{\rm{22 - 16}}}}{{{\rm{16}}}}{\rm{ \times 100 = 37}}{\rm{.5\% }}\) i.e., mass will increase by 37.5%
CHXI02:STRUCTURE OF ATOM
307631
Proton is
1 Nucleus of deuterium
2 Ionised hydrogen molecule
3 Ionised hydrogen atom
4 An \({\rm{\alpha - }}\) particle
Explanation:
Proton is an ionised hydrogen atom. A hydrogen atom is made up of one proton (present in the nucleus) and one electron (present outside nucleus). During ionisation of hydrogen atom, the electron is lost. Hence, only proton is left out.
