In the modern periodic table, properties of the elements are a periodic function of their atomic numbers. True/False

State whether the following statements are true or false: (a) Newlands divided the elements into horizontal row of eight element each. (b) According to Mendeleev's periodic law, the properties of elements are a periodic function of their atomic numbers. (c) The elements in a group have consecutive atomic numbers.

“The physical and chemical properties of the elements are periodic function of their respective atomic weights”. This statement was given by

In the modern periodic table, the elements are arranged in the increasing order of their atomic number. This arrangement is based on the modern periodic law, which states that the properties of elements are a periodic function of their atomic numbers. In the modern periodic table, each column is called a group and each row is called a period. Elements within the same group show similarity and gradation in properties. This is due to the same number of electroms in the outermost shell . Based on the above paragraph, answer the following question: What is the number of valence electrons in an element of group 1 and group 18 respectively?
