Because the atomic symbol implies a corresponding atomic number.
An atomic number is typically written as a subscript before the chemical symbol of an element. For example, the atomic number of oxygen is written as 8O. It represents the number of protons in the nucleus of an atom.
the mass goes on top and the the atomic number on the bottom ie: 12/6 C
The element is Helium witht he atomic number, 2.
Atomic symbols are the shortened version of the name of an element, often determined using its Latin name. For example, Calcium is abbreviated to "Ca" and is much easier to write out than Calcium is.
Beryllium for example would be. 7 2 Be 4 7= The mass number (+Protons and +/- neutrons added) 4 = The +protons 2 = The oxidation state. Beryllium would have 2 valance -electrons, hence the two. It has to lose 2 -electrons to be stable. For a metal it would be how many electrons it has to gain to be stable (Full valence shell). Be = Is obviously the symbol of the element.
An atomic number is typically written as a subscript before the chemical symbol of an element. For example, the atomic number of oxygen is written as 8O. It represents the number of protons in the nucleus of an atom.
The atomic number for silver is 47, which means it has 47 protons in its nucleus. To draw a simple representation, you can write "Ag" (the chemical symbol for silver) and place the atomic number (47) as a subscript to the left of the symbol.
the mass goes on top and the the atomic number on the bottom ie: 12/6 C
The element is cesium (Cs) and the cation is Cs^1+
The atomic number of nitrogen is 7. When it is a radioactive isotope you add the number of neutrons to the atomic number (equaling 15). You then write 15 over 7 next to a capital 'N' representing Nitrogen.
One way to write the isotope of bromine with 10 more neutrons than its atomic number is 81Br (atomic number 35 + 10 = 45 neutrons). Another way is to use the mass number notation and write it as bromine-81, where the mass number is the sum of protons and neutrons.
The element is Helium witht he atomic number, 2.
Atomic symbols are the shortened version of the name of an element, often determined using its Latin name. For example, Calcium is abbreviated to "Ca" and is much easier to write out than Calcium is.
Lithium is a metal element. Atomic number of it is 1.

The symbol of an atom of boron with 5 neutrons and 5 protons is ^10B. The superscript indicates the total number of protons and neutrons in the nucleus, and the atomic number (number of protons) is typically placed as a subscript.
Beryllium for example would be. 7 2 Be 4 7= The mass number (+Protons and +/- neutrons added) 4 = The +protons 2 = The oxidation state. Beryllium would have 2 valance -electrons, hence the two.
