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 N

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

*
Carbon has actually three isotopes: \(_6^12\textrmC\), \(_6^13\textrmC\) and \(_6^14\textrmC\). They all smashville247.netntain 6 protons, but six, seven and eight neutron respectively.

\(_7^14\textrmN\) 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.

The atom number is 6 for this reason \(_6^14\textrmC\) smashville247.netntains 6 protons.

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

Question

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

\<_30^64\textrmZn\>

\<_92^238\textrmU\>

\<_1^3\textrmH\>

Reveal answer

\<_30^64\textrmZn\>

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

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 electrons

There 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 electrons

There is 1 proton and also 2 neutrons.
