In medicine , for example , cobalt is extensively employed as a radiation source to arrest the development of cancer. What is isotopes and examples? Elements are defined by the number of protons in the atomic nucleus. For example , an atom with 6 protons must be carbon, and an atom with 92 protons must be uranium.
In addition to protons, the atoms of nearly every element also contain neutrons. These isotopes are called carbon, carbon and carbon What is an isotope symbol?
Isotope notation, also known as nuclear notation, is important because it allows us to use a visual symbol to easily determine an isotope's mass number, atomic number, and to determine the number of neutrons and protons in the nucleus without having to use a lot of words. How are isotopes created? Isotopes are atoms of the same element that have different numbers of neutrons but the same number of protons and electrons. The stable isotopes have nuclei that do not decay to other isotopes on geologic timescales, but may themselves be produced by the decay of radioactive isotopes.
What are compounds formed as a result of? A compound is a unique substance that forms when two or more elements combine chemically. Compounds form as a result of chemical reactions. The elements in compounds are held together by chemical bonds. A chemical bond is a force of attraction between atoms or ions that share or transfer valence electrons.
What are isotopes easy explanation? Isotopes are atoms with the same number of protons but that have a different number of neutrons. Since the atomic number is equal to the number of protons and the atomic mass is the sum of protons and neutrons, we can also say that isotopes are elements with the same atomic number but different mass numbers. How do you determine isotopes?
Look up at the atom on the periodic table of elements and find out what its atomic mass is. Subtract the number of protons from the atomic mass. This is the number of neutrons that the regular version of the atom has.
If the number of neutrons in the given atom is different, than it is an isotope. Compounds form as a result of chemical reactions. The elements in compounds are held together by chemical bonds.

Isotope analysis can be used by forensic investigators to determine whether two or more samples of explosives are of a common origin.
Most high explosives contain carbon, hydrogen, nitrogen and oxygen atoms and thus comparing their relative abundances of isotopes can reveal the existence of a common origin. Numbers of isotopes per element In total, there are nuclides that have not been observed to decay.
Some elements and hence all their isotopes are poisonous or chemically dangerous. If a radioactive isotope enters the body and is not excreted, any radiation energetic particles it emits can damage tissue and trigger cancer. Why are radioisotopes important to biologists?
