There are two in current use. For an Atomic Mass unit, one would use the symbol "u". For a Dalton one would use "Da".
A is the symbol for mass number or atomic mass of an element and Z is the symbol for Atomic number.
The symbol for molar mass is "M".
lower case u.
Symbol - F Atomic Number - 9 Mass Number - 19
atomic number = 17 mass number = 37
Hydrogen is a non metal element. Mass number of it is 1.
the symbol is Al and the charge is negative 3.
Mass number
Symbol - F Atomic Number - 9 Mass Number - 19
atomic number = 17 mass number = 37
It is not, The mass number is (A). The symbol for atomic mass is (ma)
the number above the symbol is the atomic....... of that element.
by subtracting the atomic number from the mass number. the atomic number is the one under the element's symbol and the mass number is the one above the element's symbol.
You are looking for the symbol of cesium (Cs) and indication of its mass number. The mass number is the sum of the protons and neutrons. So if every atom of cesium has 55 protons, then the mass number of this isotope is 137. The mass number is indicated in superscript before the symbol: 137Cs
A = Mass Number Z = Atomic Number N = Neutron A - Z = N
Hydrogen is a non metal element. Mass number of it is 1.
atomic mass or number?
Wiz Khalifa
the symbol scientists use to represent the atomic mass number is the letter U.
The atomic number.
