How Many Neutrons? The difference between isotopes of an element depends on the number of neutrons. To find the number of neutrons in an isotope, find the mass number of the isotope and the atomic number. The atomic number, or number of protons, is found on the Periodic Table. The ...

How Many Neutrons and Protons Can Get Along? Maybe 7,000Clara Moskowitz, SPACE.com
How many neutrons and nominal mass for {eq}\displaystyle \rm ^{1}H_2^+ {/eq}?Atomic Mass:The atomic mass of an atom or molecule can be determined based on the "number of protons and neutrons". "The total atomic mass or molecular mass of the atom or a molecule is the sum or ...
How many gold atoms are in 1650 cm3 of gold? What is the mass of the carbon atoms in 433.42 g of propane? What is the mass of carbon in 58.5 grams of NaC7H5O2? How could you determine the number of neutrons in a carbon 14 atom? How many tot...
If we press hard enough, the protons and neutrons will burst apart into what they're made of: smaller particles called quarks. We'll then have a mess of quarks -- the type of quarks called "up" and "down," which have certain masses and are the only kinds found in matter on Earth....
Protons are negatively charges and are clustered with neutrons to form the atomic nucleus. The negatively charged electrons, meanwhile, zip about at considerable distances from the nucleus in relation to the overall size of the atom, as you'll see in detail. ...
These particles, made up of protons and neutrons, are large and can only travel a short distance -- in fact, they can be stopped with just a piece of paper or even your skin. However, inhalation or ingestion of alpha particles can be very dangerous. Once inside your body, alpha ...
example,carbon atomsalways have six protons;hydrogen atomsalways have one; andoxygen atomsalways have eight. Different versions of the same element, called isotopes, can have a different number of neutrons. Elements can also gain or lose electrons to become charged, in which case they are called...
