Question 126

In a computer simulation, two identical particles are added to a neutral atom. Each particle is either a proton or an electron.

After the particles are added, the relative mass of the atom has increased by 21840\displaystyle \frac{2}{1840}18402​.

Which gives the particles added and the relative charge of the atom afterwards?

[1]
A

Two protons; relative charge +2+2+2

B

Two protons; relative charge −2-2−2

C

Two electrons; relative charge −2-2−2

D

Two electrons; relative charge +2+2+2
