"Nb" on the periodic table stands for niobium. Niobium is a chemical element with the atomic number 41 and is commonly used in alloys, superconductors, and other high-tech applications.
It depends on how picky you want to be. Yes, having the same number of nucleons they have practically the same atomic mass. No, because they don't have exactly the same atomic mass due to differences in the nuclear binding energy (and hence aren't truly "isobars", even though that's what they're called). (NB: this usage of "isobar" is from nuclear chemistry and means "nuclei with the same number of nucleons." It's not the meteorological isobar, which is something quite different and wouldn't make any sense in the context of the question.)
The atomic mass of calcium carbonate (CaCO3) is calculated by adding together the atomic masses of calcium (Ca), carbon (C), and three oxygen (O) atoms. The atomic mass of Ca is 40.08, C is 12.01, and O is 16.00. Therefore, the atomic mass of calcium carbonate is 40.08 + 12.01 + (3 * 16.00) = 100.09 g/mol.
The other product in the beta decay of zirconium-93 is niobium-93. In beta decay, a neutron in the nucleus is converted to a proton, resulting in the formation of a new element with one higher atomic number.
The element with the atomic number of 20 is calcium. Mass number is the number of protons and neutrons in the nucleus of an atom of a particular isotope, but does not determine which element it is.
The atomic number of niobium (Nb) is 41.The atomic weight of Nb is 92.906 grams per mole.See the Web Links to the left of this answer for a periodic table with more information about this element!
There is NO element with the Atomic No. of 238. Atomic No. only go to ~ 110. However, There is an element with ATOMIC MASS of 238, it is an isotope of Uranium NB . Atomic Number refers to #1 the position in the periodic table #2 the number of protons in the element #3 the number of electrons in the neutrally charged element. Atmoic Mass refers to the Sum total of all the protons and neutrons in the nucleus of an element. An element such as Uranium would be shown in the periodic table as [238/92]U. The two numbers indicating the Atomic Mass and the Atomic Number.
Niobium, formerly columbium, is a chemical element with the symbol Nb and atomic number 41. It is a soft, grey, ductile transition metal, which is often found in the pyrochlore mineral, the main commercial source for niobium, and columbite. Wikipedia Symbol: Nb Electron configuration: Kr 4d4 Atomic number: 41 Melting point: 2,469 °C Atomic mass: 92.90638 ± 0.00002 u Discoverer: Charles Hatchett Source: Google
You have to subtract the number of protons in the element by the Mass number. You find the # of protons because it the same as the Atomic number. And find the Mass Number by rounding the Atomic Mass to the nearest Whole number.

It exists. It has mass. It is used in optics to make laser crystals and switches for pulsed lasers. Niobium is an useful element.
"Nb" on the periodic table stands for niobium. Niobium is a chemical element with the atomic number 41 and is commonly used in alloys, superconductors, and other high-tech applications.
molybdenum. a black powder as used in oil additive like sulphide.
Hydrogen Atomic No. (Z) is '1' No. of protn is '1' No. of electrons is '1' Atomic Mass of the protium isotope is '1' In the Periodic Table it is found in position Mo. '1'. NB Hydrogen has three isotopes #1 protium ; 1 proton , 0 neutrons , 1 electron (Atomic Mass '1'). #2 deuterium ; 1 proton , 1 neutron , 1 electrons ( Aromic Mass '2') #3 tritium ; 1 proton , 2 neutrons, 1 electron ( Aromic mass '3').
In the expression "41 20 X," the numbers likely represent atomic numbers in the periodic table. Atomic number 41 corresponds to niobium (Nb), and atomic number 20 corresponds to calcium (Ca). Therefore, X would represent the element that comes after calcium, which is scandium (Sc) with an atomic number of 21.
No such thing as a 'Compound element'. It is either a 'Compound' or an 'Element. Germanium is an element that appears in the Periodic Table as 'Ge'. NB A compound is a COMBINATION of two or more different elements.
