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.
molybdenum. a black powder as used in oil additive like sulphide.
Calcium is a metal element. Atomic mass of it is 40.
Argon is a gas element. atomic number of it is 18.
34
The atomic number of an element equals the number of protons in the element.
The chemical element with the atomic number 41 is niobium; the electron configuration is:[Kr]4d4.5s1.
Niobium has atomic number 41. Therefore, 90Nb has 90-41=49 neutrons. Please see the link.
A-N=Z Mass number - Number of neutrons= Atomic number mass number = 80, number of neutrons = 41; 80-41=39 Atomic number for the element with mass number 80 and 41 neutrons; is 39.
molybdenum. a black powder as used in oil additive like sulphide.
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.
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!
Calcium is a metal element. Atomic mass of it is 40.
The mass number of an element is the total number of protons and neutrons in its nucleus. Given that the atomic number (number of protons) uniquely identifies an element, knowing just the mass number of 41 is insufficient to determine the specific element without additional information.
37 - rubidium 38 - strontium 39 - yttrium 40 - zirconium 41 - niobium
The atomic number is the number of protons in an atom of an element.
Atomic number = Number of protons
Argon is a gas element. atomic number of it is 18.
