We arranged the elements based on their similarities in properties and behaviors, ensuring a clear progression from more reactive to less reactive elements. This organization highlights relationships, such as atomic number and electron configuration, making it easier to understand trends across the Periodic Table. Additionally, we grouped elements with similar characteristics together to facilitate comparisons and enhance clarity in our presentation.
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 table
He arranged the elements in order of atomic number.
To arrange elements in order of decreasing first ionization energy (E i1), consider their positions in the periodic table and their electron configurations. Generally, ionization energy increases across a period from left to right due to increased nuclear charge and decreases down a group due to increased atomic size and electron shielding. Therefore, elements in the same group will have lower ionization energies than those in the previous group, and elements in the top right corner of the periodic table (like noble gases and halogens) will have the highest ionization energies.
A. A shorthand way of representing the chemical elements.
mendelev arranged the elements in the periodic table in the asending order of the mass number of 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.
On the periodic table, the elements are arranged by Atomic Mass. Helium and Hydrgen are at the way top of the table due to how they have the smallest amount of mass. The elements with the biggest mass are at the bottom.
The Periodic Table of Elements.
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.
Atomic Mass.
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.
This is called the "Periodic Law" or "Principle of Periodicity".
