The elements in the Periodic Table are arranged so that elements in the same group (column) will exhibit certain similar characteristics with others in that same group, but different periods (rows). So you can predict, with a certain degree of confidence, how a certain element may behave by where it is located on the periodic table, based on what you know about how other elements in the same group behave. This is mainly due to the valence electrons (the outermost electrons) being the same configuration as others in the same group. The valence electrons are a big determining factor as how that element will react with other elements.
They do not all behave exactly the same, but similar.
The periodic table of Mendeleev is a rational system of arrangement of chemical elements.
the answer is mendeleev
Magnesium is an Alkaline Earth element. It is a metal, and is very reactive.
"He" could refer to Dmitri Mendeleev, the creator of the periodic table. The periodic table is a tabular arrangement of the chemical elements, organized by atomic number, electron configuration, and recurring chemical properties. It allows for the prediction of an element's properties based on its position in the table.
Periodic table would be complex then. It will make study of elements difficult.
periodic table is classified into groups and periods.There are 18 groups and 7 periods in periodic table.
The periodic table of Mendeleev is a rational system of arrangement of chemical elements.
Mendeleev's prediction that there were elements missing from the periodic table was confirmed when gallium was discovered in 1875 and germanium in 1886, fulfilling the gaps Mendeleev had left in his periodic table.
The atomic number that sodium has in periodic table is 11 and valency is 1. The periodic table is a kind of table that was invented for the better study of elements and other types of compound. It makes the systematic study of elements.
Science is dependent on periodic table. It makes the study of elements easier.
The rows are used to study the change in trends. There are 7 periods in periodic table.
Study them good.

Dmitri Mendeleev created the periodic table to organize and classify the elements based on their properties and atomic weights, allowing for easier understanding and prediction of element behavior.
Iodine is classified as a halogen in the periodic table of elements. It is a non-metal and is part of Group 17 (Group VIIA) of the periodic table.
the answer is mendeleev
