basically? how they react.
some scientist guy who was good with calculations predicted qualitys of elements like, ages ago, before they were discovered.
he basically designed the Periodic Table.
if you notice, its in groups
the first column, alkali metals, get nasty with water or anything more acidic
sodium + water = fire
sodium + pure sulfuric acid = boom
-------------------------------------
They are arranged in increasing number of protons, and with respect to the number of electrons in the outer electron shell.
The elements are arranged according to increasing atomic number. The properties are periodic when arranged in this manner. Henry Moseley gave this concept.
Dmitri Mendeleev arranged the elements in periodic table according to increasing weight. He found their properties to be periodic when arranged in this pattern.
The first periodic table was developed in 1869 by Dmitri Mendeleev. He arranged the known elements by atomic mass.
newlands arranged the elements in the periodic table in order of relative atomic massNewlands arranged elements in group of eight like musical notes.
1) The elements are arranged according to vertical columns.
Mendeleev arranged the elements by increasing atomic mass instead of like today by increasing atomic number.
Dmitri Mendeleev arranged the elements in periodic table according to increasing weight. He found their properties to be periodic when arranged in this pattern.
The elements arranged according to their atomic number in the table are called periodic table.
the periodic table is arranged according to their atomic number.
the elements in the modern periodic table are arranged according to their increasing atomic number.
periodic table
atomic number
The elements are arranged in order according to the atomic number. The periodic table is arranged so that the elements in each column have similar chemical properties.
The first periodic table was developed in 1869 by Dmitri Mendeleev. He arranged the known elements by atomic mass.
According to the number of their protons
He is the founder of the periodic table. He arranged the elements according to the atomic masses. Few changes are made in his periodic table to make the modern periodic table.
Elements are arranged on the Periodic Table in the order of the atomic number, in groups and periods.
In the periodic table, the elements are arranged by atomic number
