In each element square on the periodic table there is a number that has a decimal point in it what does this number represent?

It could be the molecular mass. The decimal place represents the fact that different isotopes of each element exist in different proportions, so the listed mass is an average of sorts.

What do the horizontal rows on the periodic table represent?
Whereas the vertical columns on the periodic table are called "groups", and represent the number of electrons in an element's outermost electron shell (eg. group 2 elements have twoelectrons in their farthest energy level), the horizontal rows, known as "periods", refer to the number of energy shells surrounding the nucleus of an element.
What do the numbers on mendeleev's periodic table represent?
The Atomic number which is the number of protons in an atom's nucleus.
How many boxes are there in the periodic table?
There are 118 elements known and hence there are 118 boxes in the modern periodic table. Each box represent a given element.

What is the number of electrons in a neutral atom of an element on an periodic table?
There is none, but a neutral atom is called a neutron. There is no neutral element.
What does the decimal number in the periodic represent?
In the equation of a periodic motion it could represent the amplitude, frequency or phase.
What does the decimal number in an element key represent?
atomic mass
What form the atomic number of an element represent?
Atomic number = number of a chemical element in the periodic table of Mendeleev = number of protons in the nucleus = number of electrons in the atom

What is one thing that the atomic number represent the periodic table?
The atomic number is the number of protons in nuclei of the atoms of a given element.
What do the numbers on mendeleev's periodic table represent?
The Atomic number which is the number of protons in an atom's nucleus.
Atomic mass in the periodic table?
The number found below the name and symbol of an element on most periodic tables. Usually has a decimal, but doesn't have to.
What do whole numbers on the periodic table represent?
The whole number, the one at the top, above the element's symbol in the element box, is the atomic number. The atomic number is the number of protons per atom in that particular element. The bottom number, that is always a decimal, is the atomic mass.
What does the period number on a periodic table represent?
the Atomic number on Periodic Table is the identity of an element in the table , it gives the indications about Group, period and Block of elements it also predicts the chemical and physical properties of the element.
How many boxes are there in the periodic table?
There are 118 elements known and hence there are 118 boxes in the modern periodic table. Each box represent a given element.
What is the number listed for each element on the periodic table?
The number listed above the symbol of an element on the periodic table is the element's atomic number.
How do you find protons in elements on the periodic table?
It's the same as the Atomic number, which is the number on an element that usually has no decimal, and is the first number listed. Same goes for electrons.
