Mass number and also atomic number space two necessary pieces of information around a nucleus.

You are watching: How many protons neutrons and electrons does chlorine have

A nucleus can be represented using the price notation:

\<_Z^A\textrmX\>

Where:

A is the fixed numberZ is the atomic numberX is the chemistry symbol the the elementA - Z = variety of neutrons N

For example, chlorine (Cl) deserve to be presented as:

*
Carbon has three isotopes: \(_6^12\textrmC\), \(_6^13\textrmC\) and \(_6^14\textrmC\). They all princetoneclub.orgntain six protons, yet six, seven and eight neutron respectively.

\(_7^14\textrmN\) and \(_6^14\textrmC\) space not isotopes.

They have the very same mass number, A, yet different atomic number, Z, and also different chemical symbol - they are not the exact same element.

If the variety of protons changes, then it is a different element.

The atom number is 6 so \(_6^14\textrmC\) princetoneclub.orgntains six protons.

Question

How plenty of neutrons go \(_6^14\textrmC\) princetoneclub.orgntain?

Number of neutron = massive number - atom number = 14 - 6 = 8 neutrons.

Question

Write under the variety of particles in the adhering to nuclei:

\<_30^64\textrmZn\>

\<_92^238\textrmU\>

\<_1^3\textrmH\>

\<_30^64\textrmZn\>

Number of protons Z = 30Number of protons + neutron A = 64Number of neutrons N = 64 - 30 = 34Since this is a nucleus there space no electrons

There are 30 protons and 34 neutrons.

\<_92^238\textrmU\>

Number of protons Z = 92Number of proton + neutrons A = 238Number of neutron N = 238 - 92 = 146Since this is a nucleus there room no electrons

There are 92 protons and also 146 neutrons.

\<_1^3\textrmH\>

Number of protons Z = 1Number of proton + neutrons A = 3Number of neutrons N = 3 - 1 = 2Since this is a nucleus there room no electrons

There is 1 proton and also 2 neutrons.
