Are you talking about the number below the symbol? If so, that's the Atomic Mass number.

What is the little number immediately to the right of each elements in a compound?

The little number immediately to the right of each element in a compound is called a subscript. It indicates the number of atoms of that element present in the compound.


What is the number on the bottom of each element's box called?

The little number under the Element symbol is known as the Atomic Number. The Atomic Number represents the number of protons located at the atom's nucleus. It also tells how many electrons are in the atom, considering the atom is a stable particle, the number of electrons and protons are equal in an atom at its normal state.


What are the number of protons and electrons found in an element called?

the number of protons in an element is called the atomic number and there is no way to see how many electrons an element has.


What are the little numbers below numbers called?

they are called negative numbers. you show them like this. 3,2,1,0,-1,-2,-3,-4-------------------------------------------------If you are referring to fractions then the top number is called the numerator and the bottom number is called the denominator.---------------------------------------------------A little number like the 2 in the following expression"x2" is called a subscript.


How do you figure the shorthand notation of an element?

The atomic number of the element is the subscript (bottom number) and the mass number is the superscript (top number); and both those numbers are written to the left of the element symbol.


What is the bottom number in the fraction called?

The number on the bottom of a fraction is known as the "denominator."


The number of protons in the nucleus of an element is called?

the answer is that it is called a atomic number.


Are protons the number on top or the bottom?

For a given isotope of an element, the "top number" (e.g. 14C or carbon-14) is the atomic mass number, the total of neutrons and protons. The bottom number, if displayed, is the atomic number (e.g. 6C all isotopes of carbon have 6 protons). To find the number of neutrons, subtract the atomic number from the isotopes atomic mass number. Here, 14C will have 8 neutrons, and the result is that it is an unstable radioactive isotope. Many stable elements, however, have many more neutrons than protons.
