Mendeleev used atomic masses to classify the element, where as Moseley classified the element in terms of atomic number, he suggested that chemical and physical properties are the functions of the atomic number Elements in the periodic table is classified as Metals, Nonmetal and Metalloids. Normally Group 1 to 12 are metals... Sayed Abdul Aziem Sayed_abd2007@hotmail.com
Flourine is the most electromagnetic element on the periodic table.
Yes. In terms of electron configuration and the number of valence electrons.

The only important difference is that the modern periodic law must be framed in terms of atomic numbers, where Mendeleev framed the original periodic law in terms of atomic weights. There are only three places where this makes a difference. For cobalt and nickel Mendeleev assigned both exactly the same atomic weight -- well within the error margins at the time. For tellurium and iodine, Mendeleev insisted, wrongly, that the recognised atomic weight of tellurium was wrong, and that it had to be less than that of iodine. And the third case did not come up until later, because argon was not discovered until 1894 (element number 18, argon, has an atomic weight greater than that of element 19, potassium).
Mendeleev arranged his version of the Periodic Table in terms of ascending atomic weights and similar properties. Since it was first published in 1869, there have been updates and improvements.

The horizontal rows are called Periods. There are 7 periods in periodic table.
Usually when saying "periodic," scientists usually refer to the periodic table. This table is the shortened version of gasses, solids, liquids, and so on.
iDkkk Lmaoo !!
Elements are organised in terms of properties in same column. Properties are found to be periodic .
Group: a vertical column Period: an horizontal row
The periodic table?
Flourine is the most electromagnetic element on the periodic table.
They are groups
Yes. In terms of electron configuration and the number of valence electrons.
