Question

Arrange fundamental particles of an atom in increasing order of its weight​

Answer 1

Answer:

The increasing order for the values of e/m (charge/mass) for the electron (e), proton (p), neutron (n) and alpha particle (α) is: A.e, p, n, α B.n, p, e, α C.n, p, α, e.

Answer 2

The fundamental particles of an atom in increasing order of their weight​ are $\[electrons < protons < neutrons\]$.

Explanation:

• The fundamental particles of an atom are electrons, protons and neutrons.
• The mass of an electron is approximately $\[9.1 \times {10^{ - 31}}\,kg\]$.
• The mass of a proton is $\[1.67 \times {10^{ - 27}}\,kg\]$.
• The mass of a neutron is also approximately  $\[1.67 \times {10^{ - 27}}\,kg\]$ which is same as the mass of a proton.
• However, a neutron is slightly heavier than a proton. It is about $\[0.1\% \]$ heavier than a proton.
• Therefore, the increasing order of the fundamental particles in increasing order of their weight​ is $\[electrons < protons < neutrons\]$.
