If you mean how can you write an atomic number with the element's symbol, you write the atomic number as a subscript in front of the element's symbol.
Examples
4Be, 79Au, 109Mt
The element is Helium witht he atomic number, 2.
The atomic number is typically not used together with the atomic symbol because the atomic symbol already implies the atomic number. The atomic symbol consists of one or two letters, with the first letter capitalized, and the second letter, if present, in lowercase. The atomic number is the number of protons in the nucleus of an atom and is unique to each element.
It's quite simple. It's just the atomic mass minus the atomic number. That's because the atomic number is simply the number of protons and the atomic mass is (almost exactly) the number of protons plus neutrons. Unfortunately there is a complication. The problem is that a particular element can have more than one isotope. Each isotope has the same number of protons, but different numbers of neutrons. This can make the atomic mass a messy number that's not a nice whole number.
the mass goes on top and the the atomic number on the bottom ie: 12/6 C
The atomic number of fluorine is 9.The atomic number of sodium is 11.
The element is Helium witht he atomic number, 2.
Lithium is a metal element. Atomic number of it is 1.

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 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.

this elemnt has an atomic number that is double the atomic number of silicon?
the mass goes on top and the the atomic number on the bottom ie: 12/6 C
the answer is that it is called a atomic number.
The atomic number is equal to the number of the protons in the atomic nucleus.
The element with an atomic number that is double the atomic number of silicon is germanium, with an atomic number of 32. Silicon has an atomic number of 14.
