How did the position of `frac(35)(17)Cl` and `frac(37)(17)Cl`get fixed in the Modern periodic table?

Text Solution

Verified by Experts

In the modern periodic table, the elements are arranged in the order of increasing atomic numbers. All the isotopes of an element have same atomic number. Therefore, isotopes `._(17)^(35)CI` and `._(17)^(37)CI` having same atomic number, which is equal to 17, will be placed at the same position in the modern periodic table.

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: How many groups are there in the modern periodic table?
