When elements are arranged in order of increasing atomic number, there is a recurring pattern to their physical and chemical properties.


When elements are arranged in order of increasing atomic size, there is a recurring pattern to their physical and chemical properties within a group.

Answer 1

Answer:

The periodic law states that; When elements are arranged in order of increasing atomic number, there is a recurring pattern to their physical and chemical properties.

Explanation:

• The periodic table is a table of elements derived from the periodic law that arranges elements into columns known as groups and rows known as periods.
• Elements in the same group or family share similar chemical characteristics. For example, potassium, sodium, and lithium belong to group 1 family and, therefore, share similar chemical properties.
• Elements in the same period have the same features, such as they have the same number of energy levels. For instance, elements in period 3 have three energy levels in their atoms.
