Question

The arrangement of elements in the periodic table is based on

Answer 1

1. The elements are grouped in the current periodic table in increasing order of their atomic number.

2. The contemporary periodic law, which asserts that an element's properties are a periodic function of its atomic number, is the foundation for this arrangement.

3. Each column in the contemporary periodic table is referred to as a group, and each row as a period. .

4. A group's components exhibit gradation and resemblance in their attributes. The same number of electrons in the outermost shell are to blame for this.

5. According to the periodic law, many of the features of chemical elements undergo cyclical changes, with elements with comparable qualities reoccurring at regular intervals, if the chemical elements are enumerated in order of increasing atomic number.

Answer 2

In this question, we are asked to talk about the arrangement of elements in the periodic table.

• The elements are grouped in the current periodic table in increasing order of their atomic number.
• The contemporary periodic law, which asserts that an element's properties are a periodic function of its atomic number, is the foundation for this arrangement.
• Atomic weight and valence electrons are used to order elements in the periodic table.
• Mendeleev was able to arrange each element in a certain row (known as a period) and column because of these variables (called a group).
• According to the periodic law, many of the features of chemical elements undergo cyclical changes, with elements with comparable qualities reoccurring at regular intervals, if the chemical elements are enumerated in order of increasing atomic number.
• For instance, many of the physical and chemical characteristics repeat themselves when elements are arranged according to their rising atomic numbers.
