Question: mss of proton electron neutron...

mss of proton electron neutron

Answer

The masses of the subatomic particles are:

Proton:

  • Mass in kilograms: mp=1.672621898×10−27 kgm_p = 1.672621898 \times 10^{-27} \, \text{kg}
  • Mass in atomic mass units (a.m.u.): mp≈1.007276 a.m.u.m_p \approx 1.007276 \, \text{a.m.u.}

Neutron:

  • Mass in kilograms: mn=1.6749286×10−27 kgm_n = 1.6749286 \times 10^{-27} \, \text{kg}
  • Mass in atomic mass units (a.m.u.): mn≈1.008664904 a.m.u.m_n \approx 1.008664904 \, \text{a.m.u.}

Electron:

  • Mass in kilograms: me=9.10938356×10−31 kgm_e = 9.10938356 \times 10^{-31} \, \text{kg}
  • Mass in atomic mass units (a.m.u.): me≈5.4857990970×10−4 a.m.u.m_e \approx 5.4857990970 \times 10^{-4} \, \text{a.m.u.}
Explanation

Solution

The masses of the proton, neutron, and electron are fundamental constants, typically expressed in kilograms (kg) and atomic mass units (a.m.u.).

Proton:

  • Mass in kilograms: mp=1.672621898×10−27 kgm_p = 1.672621898 \times 10^{-27} \, \text{kg}
  • Mass in atomic mass units (a.m.u.): mp≈1.007276 a.m.u.m_p \approx 1.007276 \, \text{a.m.u.}

Neutron:

  • Mass in kilograms: mn=1.6749286×10−27 kgm_n = 1.6749286 \times 10^{-27} \, \text{kg}
  • Mass in atomic mass units (a.m.u.): mn≈1.008664904 a.m.u.m_n \approx 1.008664904 \, \text{a.m.u.}

Electron:

  • Mass in kilograms: me=9.10938356×10−31 kgm_e = 9.10938356 \times 10^{-31} \, \text{kg}
  • Mass in atomic mass units (a.m.u.): me≈5.4857990970×10−4 a.m.u.m_e \approx 5.4857990970 \times 10^{-4} \, \text{a.m.u.}
