The attraction between the positive atomic nucleus and negative electrons is changed and depends on these electrical charges..
Generally the density of the chemical elements is increasing from the top to the bottom of the periodic table of Mendeleev.
The density properties generally change as you go down the columns of the Periodic Table by increasing.
The melting temperature properties generally change as you go from left to right in the periodic table by going down/decreasing.
The melting temperature properties generally change as you go from left to right in the periodic table by no specific trend/no detail pattern.
The atomic number properties generally change as you go from left to right in the Periodic Table by increasing 1 each element.
Electronegativity increases across (left to right) the periodic table and decreases on going down.
The melting temperature properties generally change as you go down the columns of the Periodic Table by decreasing for metals and increasing for non-metals.
After lanthanum, thus the name.
Lanthanum is located on the right to the bottom side on the periodic table.
the energy level increases as we move from top to bottom in the periodic table
Dmitri Mendeleev is generally considered to be the father of the Periodic Table.
At the bottom of the Periodic Table
