Question

the charge on electron is 1.6*10^-19C then what is charge on alpha particle ​

Answer 1

the charge on alpha particle is 2e
so ans must be 2×1.6*10-19C

Answer 2

$\bold{Answer}$



$\bold{Alpha - Particle}$

Alpha particles is consist of two proton and two neutrons

Charge an Alpha particles is +2e

=> twice the charge on proton


$\bold{ According to given question}$

Charge on election

$1.6 \times {10}^{ - 19} c$

=> charge on proton and nutron are same


$\bold {Important point}/$

Because an alpha particle has no electrons to balance the positive charge of the two protons, it has a charge of +2 and can be represented as He2+. If a particle has a charge, whether negative or positive, it can be shown as a superscript. Thus He2+ means a helium atom that has lost two electrons and has a +2 charge.


$\bold{Hence}$

charge on alpha particle = +2e

$= 2 \times e$

$= 2 \times 1.6 \times {10}^{ - 19} c$

$= 32 \times {10}^{ - 19} c$
