Question

Which particle has approximately the same mass as a proton?

Answer 1

The answer is Neutron

Hope this helps :)

Answer 2

so we know that mass of proton and mass of neutron is almost same

Step-by-step explanation:

mass of the proton is given as

`m_p = 1.66 * 10^(-27) kg`

here we know that

mass of the neutron is given as

`m_n = 1.67 * 10^(-27) kg`

in terms of amu we have

`m_p = 1.007 amu`

`m_n = 1.008 amu`

so we know that mass of proton and mass of neutron is almost same
