What does the letters stand for in the periodic table of elements?
Before you find what you're looking for in this list, I thought I should just let you know that the only letter you will not find in either the names of the elements or their chemical symbols is 'J'. Otherwise, happy finding :) H - Hydrogen Li - Lithium Na - Sodium K - Potassium Rb - Rubidium Cs - Caesium Fr - Francium Ra - Radium Be - Beryllium Mg - Magnesium Ca - Calcium Sr - Strontium Ba - Barium Ra - Radium Sc - Scantium Y - Yttrium Lu - Lutetium Lr - Lawrencium Ti - Titanium Zr - Zirconium Hf - Hafnium Rf - Rutherfordium V - Vanadium Nb - Nibium Ta - Tantalum Cr - Chromium Mo - Molybdenum W - Tungsten Sg - Seaborgium Mn - Magnese Tc - Technetium Re - Rhenium Bh - Bohrium Fe - Iron Ru - Ruthenium Os - Osmium Hs - Hassium Co - Cobalt Rh - Rhodium Ir - Iridium Mt - Meitnerium Ni - Nickle Pd - Palladium Pt - Platinum Ds - Darmstadtium Cu - Copper Ag - Silver Au - Gold Rg - Roentgenium Zn - Zinc Cd - Cadmium Hg - Mercury Uub - Unumbium B - Boron Al - Aluminium Ga - Gallium In - Indium Tl - Thallium C - Carbon Si - Silicon Ge - Germanium Sn - Tin Pb - Lead N - Nitrogen P - Phosphorus As - Arsenic Sb - Antimony Bi - Bismuth O - Oxygen S - Sulphur Se - Selenium Te - Tellurium Po - Polonim F - Flourine Cl - Chlorine Br - Bromine I - Iodine At - Astatine He - Helium Ne - Neon Ar - Argon Kr - Krypton Xe - Xenon Rn - Radon La - Lanthanum Ac - Actinium Ce - Cerium Th - Thorium Pr - Praseodymium Pa - Proactinium Nd - Neodymium U - Uranium Pm - Promethium Np - Neptunium Sm - Samarium Pu - Plutonium Eu - Europium Am - Americium Gd - Gadolinium Cm - Curium Tb - Terbium Bk - Berkelium Dy - Dysprosium Cf - Californium Ho - Holmium Es - Einsteinium Er - Erbium Fm - Fermium Tm - Thulium Md - Mendelevium Yb - Ytterbium No - Nobelium Uuu - Unununium Uun - Ununnilium Uut - Ununtrium Uuq - Ununquadium Uup - Ununpentium Uuh - Ununhexium Uus - Ununseptium Uuo - Ununoctium Uue - Ununennium Unb - Unbinilium
How many nuclear elements are there?
First, I need to define what an isotope is. An isotope of an element has the same number of protons, but a different number of neutrons. So, for example, Carbon-12 has 6 protons (which is why its atomic number on the table of elements is 6), and 6 neutrons. Carbon-14 also has 6 protons, but 8 neutrons. A radioactive isotope, or radioisotope, is one that is unstable and decays over time into another isotope or even another element that has a stable configuration. Carbon-14 is what they use in "Carbon dating"; it has a half-life of 5,730 years. This means that if you had 10 pounds of carbon-14, at the end of 5,730 years, roughly half of it will have decayed into nitrogen-14. Some elements have an extremely long half-life; Uranium-235 has a half-life of 700 million years. Others have a half-life measured in a fraction of a second, like the man-made element Ununnilium-272, which has a half-life of only 10 milliseconds. For comparison, it takes 300 to 400 milliseconds to blink. This means Uun-272 has a half-life that is 30 to 40 times faster than a single blink! At this point I could go into even more detail about the different types of radioactive decay (alpha-, beta-, and gamma-), which types of decay are dangerous to human life, and so on; but this is supposed to be an answer, not a chemistry book! I will, however, point out that the average American absorbs 360 mrem's of radiation per year. Your chance of dying from cancer increases 10% if you accumulate a total of 250,000 mrems - which means you'd have to live about 695 years to accumulate that much radiation! Not much to worry about... Most elements, but not all, have at least one radioisotope. All elements with an atomic number of 80 or higher have at least one radioisotope. All isotopes of elements with an atomic number of 84 or higher are radioisotopes. Therefore, mercury (atomic number 80) is not normally radioactive, but some isotopes of it (Hg-194, Hg-197, Hg-203, and Hg-206) are radioactive; while all isotopes of Polonium (atomic number 84) are radioactive. The total number of elements that have NO stable isotopes, including naturally-occurring and man-made elements, is about 37. If you add elements with naturally-occurring radioisotopes, that number will be significantly higher. (Carbon-14, for example, is naturally occurring.)

What is group 11 on the periodic table?
Well the question is a little confusing. So I am giving the two possible answers. The eleventh element is sodium. The elements in the eleventh group are copper, silver, gold and roentginum
How do you calculate nitrogen balance?
Nitrogen Balance = Nitrogen intake - Nitrogen loss Nitrogen intake = Protein intake (g/day) / 6.25 Urinary Urea Nitrogen (UUN) determined with 24hr urine collection Nitrogen loss = UUN (g/day) + 4g (to account for random nitrogen loss)

Darmstadtium, previously known as ununnilium, with the chemical symbol Ds (previously Uun) has the atomic number 110.
What groups are metal?
This group, except for its radioactive member Uun, is often called the "coinage" metals. The specific metal names are copper, silver, and gold.
