Mar 13, 2018· How to Calculate Subatomic Particles ... Locate the atomic number for the number of protons and electrons in the atom on the periodic table. The number of protons and electrons is equal to the atomic number. Calculate the number of neutrons by subtracting the atomic number from the isotope number. For example, Carbon 14 has an isotope mass of ...

Feb 06, 2015· The atomic number is the lower of the two numbers printed on most standard periodic tables. The mass is the atomic number + the number of neutrons. Here's calcium: Atomic number 20 If the isotope has 22 neutrons the atomic mass is 42. Here is Tantalum: Atomic number: 73 If it has 109 neutrons the atomic mass is 73+109=182
Tantalum has the atomic number 73, snuggling the element between hafnium, niobium, and tungsten in the transition metal section of the periodic table.

Tantalum is a shiny grey, extremely hard, stretchable heavy metal from the vanadium group, which is very pliable and weldable. Tantalum is among the highmeltingmetals, is extremely resistant to acids (except hydrofluoric acids) and has a high absorptive capacity for hydrogen and nitrogen.
Properties. Tantalum is a gray, heavy, and very hard metal. When pure, it is ductile and can be drawn into fine wire, which is used as a filament for evaporating metals such as is almost completely immune to chemical attack at temperatures below 150 o C, and is attacked only by hydrofluoric acid, acidic solutions containing the fluoride ion, and free sulfur trioxide.

The main task of the investigations was the evaluation of the effect of the ratio of the concentration of tantalum and rhenium in the ZhS32 alloy on the rate of high temperature gas corrosion in order to optimise this ratio for improving the parameters of hightemperature corrosion resistance.
The tantalum was inhaled or insufflated in beagle dogs as a partly neutronactivated 182Ta powder with a specific activity of about 2 microcuries/g for inhalation studies; for insufflation, it was blended with tantalum powder with a specific activity of about 5 microcuries/g. Airborne concns approximated 1 g/cu m at an aerodynamic mass ...
There are two isotopes in naturally occurring tantalum: tantalum180m and tantalum181. Tantalum180m is the metastable isotope and that is why it occurs .
