Because the atomic symbol implies a corresponding atomic number.

How can you write an atomic number?
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.Examples4Be, 79Au, 109Mt
How do you write atomic numbers in symbolic notation?
the mass goes on top and the the atomic number on the bottom ie: 12/6 C
What is the definition for atomic symbol?
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.
Write the name and atomic number for He?
The element is Helium witht he atomic number, 2.
How do you write an isotope in shorthand?
Usually, the base element name followed by the mass number 'A', such as Carbon-12. You can also use the atomic symbol preceded by the mass number as a superscript. Some isotopes have special names and atomic symbols: Hydrogen-2: Deuterium (D) Hydrogen-3: Tritium (T) Helium-2: Diproton (Theoretical, not actually possible because of physics-y stuff)

A radioactive isotope has eight neutrons Write the atomic number and mass number of this radioactive nitrogen as a chemical symbol with a subscript and superscript?
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.

What are two ways to write the isotope of bromide that has 10 more neutrons than its atomic number?
1- the name then the nuclear symbol.

Write the symbol of the ion with a 1 plus charge atomic number 55 and mass number 133?
The element is cesium (Cs) and the cation is Cs^1+
Write out atomic number for lithuim?
Lithium is a metal element. Atomic number of it is 1.
Write the name and atomic number for He?
The element is Helium witht he atomic number, 2.
A symbol used to write a number?
factor
How do you write money in decimal form?
You write the whole number of money units, for example dollars, then a decimal point, and then typically two decimals for the fractional part, often called "cents". The number of decimals may vary for some countries. You also write the monetary symbol, such as $, the Euro symbol, etc., sometimes before, sometimes after, the number. Here, too, the details may vary by country.

What happens to the mass number of an atom during beta decay?
When you write out the symbol for an isotope, it has two numbers before the chemical symbol....the bottom one is the atomic number (#protons) and the top one is the atomic mass (#protons + # neutrons). Since the letter abbreviation is given, the bottom number is kind of redundant. So, sometimes people will write the abbreviation as the letter abbreviation followed by the mass number. So, Rb-82 would have 37 protons and 82-37 neutrons (45). Beta particles would be written as a beta with the top number being zero (negligible mass for this purpose) and the bottom number being -1. So, if you lose a zero from the atomic mass, there is no change. If you lose a negative one from the atomic number, the atomic number increases by 1. So, for example, Th-234 has an atomic number of 90. Loss of a beta doesn't change its mass (still 234), but changes its identity to 91, which is the element Protocinium (Pa-234).
