"Atomic number" is a characteristic of a chemical element and equals the number of protons in each nucleus of an atom of the element.
Atomic number: number of protons or electrons in a neutral atomMass number: sum of protons and neutrons in the atomic nucleusAtomic mass number is not a very correct expression.
Beryllium Atomic number: 4 Atomic Mass: 9.012
By N, I assume you mean Nitrogen. Nitrogen's Atomic number is 7, and its atomic mass is ~14.011.
if you mean atomic number then the answer is cadmium.
The atomic number of an element is equal to the number of protons in its nucleus. This is because the atomic number represents the unique identity of an element based on the number of protons it contains.
"Atomic number" is an expression for chemical elements, not for compounds.
Atomic number: number of protons or electrons in a neutral atomMass number: sum of protons and neutrons in the atomic nucleusAtomic mass number is not a very correct expression.
X represents the element of addition in the expression.
atomic number is 37
After the IUPAC rules, atomic mass is an expression used only for the mass of isotopes (in atomic mass units).
Beryllium Atomic number: 4 Atomic Mass: 9.012
The atomic number is the number of protons in the nucleus of the atom.
The meaning of the atomic number is: number of protons and electrons (for californium is 98).
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.
Atomic number = Number of protons = Number of electrons (in the neutral state) Also the atomic number is number of a chemical element in the periodic table of Mendeleev.
By N, I assume you mean Nitrogen. Nitrogen's Atomic number is 7, and its atomic mass is ~14.011.
If you mean to ask what element has an atomic number of 13, then the answer is aluminum (Al).
