Mass number and atomic number space two necessary pieces the information about a nucleus.
You are watching: How many neutrons are in cl
A nucleus have the right to be represented using the symbol notation:
<_Z^A extrmX>
Where:
A is the massive numberZ is the atom numberX is the chemistry symbol that the elementA - Z = number of neutrons NFor example, chlorine (Cl) have the right to be shown as:
(_7^14 extrmN) and also (_6^14 extrmC) are not isotopes.
They have the exact same mass number, A, yet different atomic number, Z, and also different chemical symbol - they space not the very same element.
If the variety of protons changes, climate it is a different element.

The atomic number is 6 for this reason (_6^14 extrmC) includes six protons.
How many neutrons does (_6^14 extrmC) centregalilee.comntain?
Reveal answerup

Number of neutrons = massive number - atomic number = 14 - 6 = 8 neutrons.
Write under the number of particles in the following nuclei:
<_30^64 extrmZn>
<_92^238 extrmU>
<_1^3 extrmH>

<_30^64 extrmZn>
There space 30 protons and 34 neutrons.
<_92^238 extrmU>
Number of proton Z = 92Number of protons + neutrons A = 238Number of neutron N = 238 - 92 = 146Since this is a cell centregalilee.comre there are no electronsThere room 92 protons and also 146 neutrons.

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