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

Mendeleev's version of the Periodic Table was organized by increasing mass. The modern periodic table is now organized by atomic number.
They represent the valance electrons in each element. Roman numerals do no represent the valence electrons but it is the group number given by mendeleef.
This depends on the periodic table but it is either the atomic number (the number of protons) or the atomic mass (the number of protons and neutrons). The integer number will be the atomic number and the larger number will be the atomic mass. The exception is hydrogen which has an atomic number of 1 and an atomic mass of 1 (very close to it).
The largest number of squares that can be uncovered is 710.
In the equation of a periodic motion it could represent the amplitude, frequency or phase.
- Atomic number - Symbol - Name of element - Atomic mass they are not in order.. Hope i helped :-P
yes, the number of dots represent the number of valence electrons in the periodic table.
Think of the largest number you can. Then square it. Then square that one. Since numbers don't stop, squares don't stop either.
Following are mentioned in the squares:1. Symbol of element2. Atomic number
Astatine is the largest metalloid on the periodic table. This metalloid has an atomic number of 85. Its molar mass is 210 gram per mol.
Pick three numbers. If the square of the largest number is equal to the sum of the squares of the other two, then the three numbers could represent the sides of a right triangle.
The atomic number is the number of protons in nuclei of the atoms of a given element.
The Atomic number which is the number of protons in an atom's nucleus.
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.
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
