Question

How much heavier is an alpha particle than an electron?

Answer 1

The mass of the alpha particle is approximately 7300 greater than that of electron.

Step-by-step explanation:

The mass of electron =
`9.11* 10^(-31)\ kg`

The mass of the alpha particle = tex]6.64424\times 10^{-27}\ kg[/tex]

Thus, the ratio of the mass of alpha particle and mass of electron is:

`(m_(alpha\ particle))/(m_(electron))=(6.64424* 10^(-27))/(9.11* 10^(-31))`

`(m_(alpha\ particle))/(m_(electron))=7293.35\cong 7300`

So,

The mass of the alpha particle is approximately 7300 greater than that of electron.

Answer 2

An electron weighs 1/1836 atomic mass unit and, on the other hand, an alpha particle weighs 4 atomic mass unit.

4 amu / (1/1836 amu) = 7344

Therefore, an alpha particle is 7344 times heavier than an electron.

Hope this answers the question. Have a nice day.
