Just multiply 151 x 0.0001
That will equal:
0.00151 km or if you want to round it then it would be 0.02km
Remember....
mass number= atomic number + number of neutrons
If the mass number is 19 and the atomic number is 9, then the number of neutrons is 19-9 which is 10.
This looks correct to me! <3 have a good day
Carbon:
1s is filled. 2s is filled. 2p is shown to contain two electrons in one orbital and no electrons in the other two orbitals.
