Respuesta :

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.

Answer:

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

Explanation:

The mass of electron = [tex]9.11\times 10^{-31}\ kg[/tex]

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:

[tex]\frac{m_{alpha\ particle}}{m_{electron}}=\frac{6.64424\times 10^{-27}}{9.11\times 10^{-31}}[/tex]

[tex]\frac{m_{alpha\ particle}}{m_{electron}}=7293.35\cong 7300[/tex]

So,

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