As of 2014, there are 15 isotopes of carbon. They are C-8 through C-22. Only C-12 and C-13 are stable, while the other isotopes are radioactive, and of these, only C-14 is found in nature.
C-14 is famous for its use in carbon dating and has a half-life of 5,700 years. This means after 5,700 years, half of the carbon will have decayed into nitrogen-14.
C-11 is the most stable of the man-made isotopes, with a half-life of a little over 20 minutes. The other radioisotopes have half-lives that last for seconds or fractions of seconds. C-13 is used in research and medicine, and C-12 is used to establish the atomic weight of other isotopes.Learn More
The atoms involved in ionic bonding are held together by an electrostatic force of attraction between a positive and a negative ion. Ionic bonds are only formed between metals and non-metals.Full Answer >
Alkanes have no double or triple bonds, alkenes have one or more double bonds and alkynes have one or more triple bonds. Alkanes, alkenes and alkynes are all types of hydrocarbons.Full Answer >
An atom of boron has three valence electrons. The valence electrons of boron occupy the second orbit around the nucleus of the boron atom. Thus, the boron atom has an electronic configuration of [He] 2s2 2p1.Full Answer >
The element phosphorus has five valence electrons. Valence electrons refer to the amount of electrons in the outer shell of an atom. If an orbital is not full of atoms, it is likely to try to fill or deplete it in order to become more stable.Full Answer >
