Question

if an electron has a charge -1.6 × 10 to the power minus 19 coulomb, the charge on the nucleus of an atom of carbon is ___________c.​

Answer 1

Answer:

it is simple.

carbon atom

atomic no is 12. i.e. no of electrons or no of protons are 12

charge of 1 electron = - 1.6×10^-¹⁹ C

then,the charge of 1 proton =+ 1.6×10^-¹⁹ C

now for 12 protons,

charge of 12 protons= 12×1.6×10^-¹⁹ C

=19.2 × 10^-¹⁹C

note : just multiply the atomic no and charge of proton

( it is useful mark it as brainliest answer)
