Mass number and atomic number space two vital pieces the information around a nucleus.
You are watching: How many protons and neutrons does chlorine have
A nucleus can be represented using the symbol notation:
Where:A is the mass numberZ is the atom numberX is the chemical symbol the the elementA - Z = variety of neutrons N
For 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, yet different atomic number, Z, and different chemical symbol - they are not the very same element.
If the variety of protons changes, climate it is a various element.Question
How numerous protons does \(_6^14\textrmC\) mmsanotherstage2019.comntain?Reveal answer
The atomic number is 6 for this reason \(_6^14\textrmC\) mmsanotherstage2019.comntains 6 protons.
How plenty of neutrons go \(_6^14\textrmC\) mmsanotherstage2019.comntain?Reveal answer
Number of neutrons = massive number - atomic number = 14 - 6 = 8 neutrons.
Write under the number of particles in the adhering to nuclei:
Number of protons Z = 30Number of protons + neutrons A = 64Number of neutrons N = 64 - 30 = 34Since this is a nucleus there space no electrons
There room 30 protons and 34 neutrons.
\<_92^238\textrmU\>Number of protons Z = 92Number of protons + neutrons A = 238Number of neutron N = 238 - 92 = 146Since this is a cell core there room no electrons
There room 92 protons and 146 neutrons.

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