Are you talking about the number below the symbol? If so, that's the Atomic Mass number.
What else can I help you with?
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.
Each element has been assigned a number what is it called?
The numbering arrangement of elements is called the atomic number. Atomic number determines the number of protons in an element's nucleus and defines its unique chemical properties.
Atoms that are the same kind is called?
Isotopes - atoms with the same atomic number, number of protons and number of electrons
How do you find neutrons and protons on a periodic table?
Everything is made up of atoms. An atom is the smallest amount you have have of an Element (you find these on the periodic table of elements) The atom is made of a nucleus and shells. Inside the nucleus are protons and neutrons. And in the shells are electrons.
How do you calculate protons and neutrons?
If you think to the number of protons in an element atom this number is equal to atomic number of this element. The calculation of the mass of the proton and other properties are another questions and problems.
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 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.
Bottom number of each element in periodic table?
The bottom number of each element in the periodic table typically represents its atomic number, which indicates the number of protons in the nucleus of an atom of that element. This number also defines the element's identity and its position in the periodic table. Additionally, some elements may have a number associated with their atomic mass, which is the weighted average mass of an element's isotopes.
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.
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.
What are atoms of an element that have the same number of protons as other atoms of that element but a different number of neutrons called?
They are called isotopes,
What are the number of protons and electrons found in an element?
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 is the number in front of an element called?
atomic number
