there are 50
Dysprosium (Dy) is atomic number 66.
the number above the symbol is the atomic....... of that element.
Krypton is an element with symbol Kr and atomic number 36.
The symbol of sodium is Na and its atomic number is 11.
The Atomic Number Is Located On The TOP Of The Element Symbol. So Example. 14<ATOMIC NUMBER> Si<Symbol> 28.086<Atomic Mass> Silicon <The Name> This Is The Correct Order Of An Element That Should Be Labeled.
Americium, with the chemical symbol Am, is the chemical element with the atomic number 95.
Dysprosium has atomic number 66 so would normally have 66 electrons.
The atomic number of the element with the symbol Be (Beryllium) is 4.

The symbol of sodium is Na and its atomic number is 11.
The symbol of sodium is Na and its atomic number is 11.
Each column will generally have the symbol of the element (sometimes name of the element also), the atomic number, the mass number, the state in which the element is present at room temperature. Some periodic table will also have the electronic configuration or electronegativity.
silicon is the only element with an atomic number of 14. (Si is the symbol on a periodic table)
The element symbol represents one mole of element , atomic number represents number of protons, atomic mass represents sum of protons and neutrons.
