Mass number and also atomic number are two important pieces that information about a nucleus.

You are watching: How many protons are there in any cl atom?

A nucleus can be represented using the symbol notation:

<_Z^A extrmX>

Where:

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

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

*
Carbon has three isotopes: (_6^12 extrmC), (_6^13 extrmC) and also (_6^14 extrmC). They all ptcouncil.netntain six protons, however six, seven and eight neutron respectively.

(_7^14 extrmN) and also (_6^14 extrmC) are not isotopes.

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

If the number of protons changes, then it is a various element.

Question

How many protons go (_6^14 extrmC) ptcouncil.netntain?

Reveal answer
up


down
The atomic number is 6 for this reason (_6^14 extrmC) includes six protons.

Question

How numerous neutrons go (_6^14 extrmC) ptcouncil.netntain?

Reveal answer
up


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

Question

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

<_30^64 extrmZn>

<_92^238 extrmU>

<_1^3 extrmH>

<_30^64 extrmZn>

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

There room 30 protons and 34 neutrons.

<_92^238 extrmU>

Number of protons Z = 92Number of proton + neutron A = 238Number of neutron N = 238 - 92 = 146Since this is a cell ptcouncil.netre there space no electrons

There space 92 protons and 146 neutrons.

<_1^3 extrmH>

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

There is 1 proton and also 2 neutrons.
