An element is any substance that has only one type of atom in it (e.g. aluminium atoms). Every known element is presented on the Periodic Table of the Elements and classified into groups and periods. Some of the elements either never did or don't now naturally occur, and so scientists must synthesise them.
No currently known element has an atomic number of 255. If you look at the periodic table, you will see that the element with the highest atomic number is ununoctium, which has atomic number 118.
if you look @ the periodic table, you will find the tiny # above the element... that is its atomic #.
First of all, you spelled "element" wrong. And to find the Atomic Number of an element, you look at the number on the top of the element in the Periodic Table. For example, Hydrogen is 1, 1 is its atomic number. The atomic number is also the number of protons and electrons in an element.
Atomic mass - Atomic weight are the same , so look at your periodic table and below every element it will give you atomic mass.
To find the total number of electrons in an element, first you need to look up the element's atomic number. That number tells you how many protons are in the element. Then, look up the net charge of the element. The number of protons subtracted by the elements net charge will give you the number of its electrons.
Look at the element's atomic number.

If you look up any element on google.com you will see all the basic information, including the atomic number. Atomic numbers are also given in the periodic table of the elements (which you can also look up on google).
if you look @ the periodic table, you will find the tiny # above the element... that is its atomic #.
The atomic number is usually written to the lower left of the atomic symbol. The atomic mass is usually written to the upper right of the atomic symbol. So, carbon-14 would look like this: 6C14

The number of protons is the same as the atomic number of an element, which is found on the periodic table. Locate the element on the periodic table and look for the number above the element's symbol to find the number of protons.
