Mass number and atomic number room two important pieces that information around a nucleus.
You are watching: What is the number of neutrons in chlorine
A nucleus deserve to be stood for using the price notation:
\<_Z^A\textrmX\>
Where:
A is the massive numberZ is the atomic numberX is the chemical symbol the the elementA - Z = variety of neutrons NFor example, chlorine (Cl) deserve to be shown as:
\(_7^14\textrmN\) and \(_6^14\textrmC\) space not isotopes.
They have the same mass number, A, but different atomic number, Z, and different chemical symbol - they room not the very same element.
If the number of protons changes, climate it is a different element.

Number of neutron = massive number - atomic number = 14 - 6 = 8 neutrons.
Write under the number of particles in the adhering to nuclei:
\<_30^64\textrmZn\>
\<_92^238\textrmU\>
\<_1^3\textrmH\>

\<_30^64\textrmZn\>
There space 30 protons and also 34 neutrons.
\<_92^238\textrmU\>
Number of proton Z = 92Number of protons + neutron A = 238Number of neutrons N = 238 - 92 = 146Since this is a cell core there space no electronsThere space 92 protons and 146 neutrons.

\<_1^3\textrmH\>
Number of proton Z = 1Number of proton + neutrons A = 3Number of neutron N = 3 - 1 = 2Since this is a cell nucleus there space no electronsThere is 1 proton and also 2 neutrons.
