Mass number and also atomic number are two vital pieces that information around a nucleus.

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

A nucleus have the right to be stood for using the prize notation:

\<_Z^A\textrmX\>

Where:

A is the massive numberZ is the atom numberX is the chemical symbol the the elementA - Z = variety of neutrons N

For example, chlorine (Cl) have the right to be shown as: Carbon has actually three isotopes: \(_6^12\textrmC\), \(_6^13\textrmC\) and \(_6^14\textrmC\). They every invernessgangshow.netntain 6 protons, but six, seven and eight neutron respectively.

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

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

If the number of protons changes, climate it is a different element.

Question

How many protons go \(_6^14\textrmC\) invernessgangshow.netntain?

up

down
The atomic number is 6 for this reason \(_6^14\textrmC\) invernessgangshow.netntains 6 protons.

Question

How many neutrons does \(_6^14\textrmC\) invernessgangshow.netntain?

up

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

Question

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

\<_30^64\textrmZn\>

\<_92^238\textrmU\>

\<_1^3\textrmH\>

up

down
\<_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 space 30 protons and also 34 neutrons.

\<_92^238\textrmU\>

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

There are 92 protons and 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 are no electrons

There is 1 proton and also 2 neutrons.
