ionization radiation comes from radioactive atoms, numerous of which take place naturally in the environment. Radiation atoms, just like any kind of other kind of matter, have the right to be gas, liquid, or solid.

You are watching: The atomic number of carbon is 6. its nucleus must contain:

Atoms space the structure blocks the matter. Their framework determines their elemental and chemical properties.

Atoms room composed that a nucleus, include protons and neutrons, surrounded by a cloud of electrons.

The number of protons in the nucleus determines the identification of the atom (chemical element).For example, a carbon atom has six protons. If you to be able to include another proton to the carbon nucleus, friend wouldn’t have a carbon atom anymore: you’d have actually a nitrogen atom instead.

Most atoms are stable, meaning they have actually a great balance the neutrons and also protons. Yet some atoms have an unstable combination blend the protons and also neutrons. Isotope are creates of facets that have a different variety of neutrons.

Atoms seek to be stable; so, to obtain to a more stable state, the atom expels power from the cell core in the form of a particle or ray.

This process is known as radioactivity, the unstable atom is said to it is in a radioactive atom, and the power that’s exit is radiation.After an atom expels power from the nucleus, the ingredient of the cell core changes, and also we space left v a different facet that is much more stable. This procedure is well-known as radiation decay.

To see an example of how this process works, watch below:

Radioactive degeneration Example

Think that the carbon atom discussed above. Every carbon atom has six protons, and the bulk of carbon atoms have six neutrons.


A carbon-12 atom has actually 6 proton (6P) and 6 neutron (6N).

But some varieties of carbon have much more than 6 neutrons. We speak to forms of elements that have a different number of neutrons, isotopes. Because that example, carbon-14 is a radioactive isotope the carbon that has six protons and eight neutrons in that nucleus. We call it carbon-14 due to the fact that the total number of protons and neutrons in the nucleus, also known together the massive number, adds as much as 14 (6+8=14).

If we want to abbreviation the surname of an isotope, we’d usage the element symbol and also the mass number, for this reason carbon-14 would certainly be abbreviated C-14.

Because carbon-14 has six protons, that is quiet carbon, yet the two extra neutrons do the cell core unstable. In stimulate to with a an ext stable state, carbon-14 releases a negatively charged bit from that is nucleus the turns one of the neutrons into a proton.


This brand-new configuration that the cell core – with seven protons and also seven neutrons – leaves the atom much more stable, however it is no much longer a carbon atom. Because one that the neutrons turned into a proton, the atom is now a nitrogen atom.

In the carbon-14 example, the atom gives off radiation native the cell core to with a more stable state. In law so, the composition of the cell core changes, and we space left v a different facet that is more stable. This procedure is well-known as radiation decay.

To summarize, right here are some crucial terms:

Radioactivity is the spontaneous release of energy from an stormy atom.Radioactive material is a solid, liquid, or gas that offers off radiation.Radiation is the power that comes out of a radioactive atom.Radioactive isotopes, additionally known together radionuclides, space radioactive atom of the same element that have various numbers that neutrons.Radioactive decay is the adjust from an stormy atom come a much more stable atom by the emission of radiation.

Different radiation isotopes offer off different kinds the radiation, and decay at different rates. To learn more, click here.

Atom— The smallest particle of connected to can get in into a chemistry reaction.

Electron — one elementary fragment with a negative electrical charge and a fixed 1/1837 the of theproton. Electron surround the new kurusf anatom due to the fact that of the attraction between their an unfavorable charge and also the optimistic charge the the nucleus. A secure atom will have actually as numerous electrons together it has protons. The variety of electrons that orbit an atom identify its chemistry properties.See alsoneutron

Ionizing radiation — any radiation qualified of displacingelectronsfromatoms, thereby producingions. High sheep of ionization radiation may create severe skin or tissue damage.See alsoalpha particle,beta particle,gamma ray,neutron,x-ray.

Isotope — A nuclide of anelementhaving the exact same number ofprotonsbut a various number ofneutrons.

Neutron — A tiny atomic fragment possessing no electric charge commonly found within an atom’snucleus. Neutron are, together the name implies, neutral in your charge. The is, they have neither a confident nor a negative charge. A neutron has about the very same mass together aproton.See alsoalpha particle,beta particle,gamma ray,nucleon,x-ray.

Nucleus — The central part the anatomthat containsprotonsandneutrons. The cell core is the heaviest component of the atom.

Proton — A little atomic particle, typically found in ~ an atom’snucleus, that possesses a positive electric charge. Even though protons andneutronsare about 2,000 times heavier 보다 electrons, they space tiny. The number of protons is distinct for every chemical element.See alsonucleon.

Radiation — power moving in the type of corpuscle or waves. Familiar radiations room heat, light, radio waves, and also microwaves.Ionizing radiation a an extremely high-energy type of electromagnetic radiation.

Radioactivedecay — disintegration of the new kurusf an unstableatomby the release ofradiation.
