|---|---|---|
| Neutrons | 16 | 45 |
| Electrons | 18 | 36 |
| Mass number | 31 | 80 |
| Net charge | 3- | 1- |
How many neutrons are in an element?
The atomic number of the element equals the number of protons. Calculating the number of neutrons then becomes atomic mass of the isotope minus the atomic number of the element equals the number of neutrons. For uranium-235, atomic number 92, the number of neutrons is 235-92=143, or 143 neutrons.
What is the electron configuration of P?
In writing the electron configuration for Phosphorus the first two electrons will go in the 1s orbital. Since 1s can only hold two electrons the next 2 electrons for Phosphorous go in the 2s orbital. The next six electrons will go in the 2p orbital. The p orbital can hold up to six electrons.
How do you determine the number of neutrons in an atom?
To find the number of neutrons in an atom of the isotope, simply subtract the number of protons (atomic number). So, carbon-13 has 7 neutrons, because carbon has atomic number 6.
