Lasers are utilized in industry and research to do many things, including using intense laser light to excite other molecules to observe what happens to them. Here are some typical lasers and their emission wavelengths (in nanometers): Argon fluoride (UV): 193 Krypton fluoride (UV): 248 Xenon...
How many shells does argon have? What is potassium-argon dating? What is the mass number of argon? How many protons does argon have? What is the molar mass of argon? How many neutrons are in argon? What is potassium-argon dating used for?
The valency of an atom is the maximum number of bond pairs an atom can make with other atoms. The remaining unshared pairs of electrons on an atom after bonding is called the lone pairs which are the difference b...

There are many different ways to produce photons, but all of them use the same mechanism inside an atom to do it. This mechanism involves the energizing of electrons orbiting each atom's nucleus. How Nuclear Radiation Works describes protons, neutrons and electrons in some detail. For example,...
(hundreds of thousands of years), uranium will eventually lose so many particles that it will turn into lead. This process of decay can be greatly accelerated in what is known as a chain reaction. Instead of disintegrating naturally and slowly, the atoms are forcibly split by bombardment with...
Thanks to its extraordinary radiopurity, Borexino has definitively observed the two main fusion reactions in stars and will soon weigh in on a controversy relating to the birth of the Sun that challenges the basic assumptions of the Solar Standard Model, write Gianpaolo Bellini and Aldo Ianni. ...
transition probabilities and branching ratios as well as cross sections of a variety of nuclear – mainly neutron- and charged-particle-induced – reactions of these isotopes is a precondition for the evaluation of scientific data in any of these research areas. But how reliable are the presently...
What product is formed by beta decay of krypton-87? Why is energy lost in beta decay? Why does alpha decay occur? What happens when carbon-10 undergoes beta decay? How are new elements formed in beta decay? What is emitted in alpha decay?
How many protons and electrons are in the Br- ion? How many valence electrons does phosphorus (P) have? How many valance electrons do the element have? Sr How many valence electrons do the alkali metals have? A. 1 B. 2 C. 7 D. 8 ...
