Group one elements are the most reactive with group 7 elements as it is the easiest way for the elements to complete their outer shell as the group one element gives its extra electron to the group 7 element and then the group 7 element has a full shell too.

Meneleev arranged the elements
Yes, there are exceptions to periodic trends such as the noble gases being nonreactive and transition metals having multiple oxidation states. Our group arranged elements in a periodic table based on their electron configurations and properties to help identify patterns and relationships between elements. The arrangement helps make predictions about an element's behavior based on its position in the table.
The logical way is to be remembered that chemical properties of elements have a periodic character.
The elements are arranged in what is called the periodic table.
The Periodic Table of Elements.
Elements arrange in the periodic table based on their atomic number, which is the number of protons in the nucleus of each atom. Elements are grouped together based on similar characteristics and properties. This organization helps to predict how elements will behave and form compounds.
Atomic Mass.
By discovering the elements proton number, it became easier for scientists because the elements had similar properties. And they could arrange it by increasing proton number, valence electrons or electronic configuration.
Group one elements are the most reactive with group 7 elements as it is the easiest way for the elements to complete their outer shell as the group one element gives its extra electron to the group 7 element and then the group 7 element has a full shell too.
The periodic law states that the properties of elements repeat in a predictable way when elements are arranged in order of increasing atomic number into groups with similar properties.
