What is xenon mass number?
Xenon is a non metal element. Atomic mass of it is 131.
What letters are used to designate atomic number and mass number in isotopic notation of atoms?
The atomic number is denoted by the letter "Z" and the mass number is denoted by the letter "A" in isotopic notation of atoms.
Which element has the atomic mass 35.453 grams?
The element with an atomic mass of 35.453 grams is chlorine. It is a halogen gas with the chemical symbol Cl and atomic number 17.
What is the symbol for 12p 10e 12n?
The symbol for an element is typically written as [A-Z][a-z][number], where A is the element's atomic number, Z is the element's chemical symbol, and the number represents the sum of protons and neutrons (called mass number). So, for 12 protons, 10 electrons, and 12 neutrons, the symbol would be Mg.
What and the difference between an atomic symbol and a chemical symbol?
An atomic symbol represents a specific isotope of an element, including both the element symbol and the atomic mass number. A chemical symbol, on the other hand, is just the unique abbreviation for an element on the periodic table.
