Answer Text:
The Periodic table
- Is a table showing the arrangements of elements in order of their relative atomic masses.
- Is based on the ideas of Dmitri Ivanovich Medeleev.
- The modern periodic table is based on Medeleev’s periodic law which states that:
“The properties of elements are a periodic functions of
their relative atomic masses”
- The modern periodic law itself states that:
“The properties of elements are a periodic functions of their atomic numbers”
