he arranged his Periodic Table by each elements Atomic Mass
The reason the periodic table was created in the first place was to illustrate the "periodic" physical properties of the known elements of the time. Because of this, the properties of elements that were "missing" from the table could be extrapolated from the periodic trends seen in the known elements.
anions are negatively charged species anions are not seen on the Periodic Table. however the elements on the right end of the periodic table (except for noble gases, group 18) have a strong tendency to accept electrons are become anions
J is the only letter not present in the periodic table. Q is only seen once (ununquadium), as are X (xenon) and V (vanadium), but every other letter of the alphabet is present.
KL is often used as an abbreviation for potassium iodide, a chemical compound composed of potassium and iodine. It is commonly used in laboratories for various chemical reactions and in medical settings as a source of iodine.
It wasn't necessary, but it was very helpful. By arranging the elements in a periodic table, it makes it much easier to see patterns and trends in the properties of the elements. For instance, all of the elements in each column of the periodic table have similar properties because their electron configurations are related. Using the periodic table, you can predict with fairly good accuracy the properties of an element you've never even seen just based on where it is in the periodic table. It is a very powerful tool for chemists.
The group of noble gases (Group 18) does not follow the normal trends seen in other groups on the periodic table. This is because they have full outer electron shells, making them very stable and unreactive compared to other elements.
The periodic table is just ONE table. There are not sub-tables. The periodic table is divided into periods (the horizontal rows of the table) and groups (the vertical columns). As you move horizontally across the table, an increase is the atomic number is seen, along with trends in acidity, bonding behavior, and reactivity. The groups are arranged to contain elements that have similar properties. For example, Group 1 is called the alkali earth metals group; all are light, highly reactive metals. Many more trends and groupings exist.

Elements
In Mendeleev's periodic table, several key trends were observed, including the periodicity of element properties such as atomic mass, reactivity, and valence. He arranged elements in order of increasing atomic mass, which revealed recurring patterns in their chemical behavior. Mendeleev also left gaps for undiscovered elements, predicting their properties based on the trends he observed, which demonstrated the predictive power of his periodic arrangement. This laid the groundwork for the modern periodic table, where elements are organized by atomic number.
On the Periodic Table of elements, electronegativity increases as you move left to right across a period.

The modern periodic table doesn't, but someone probably organized the periodic table by characteristics. A few elements have multiple characteristics of various groups or periods.... Ergo, it would be fitting to place an element in multiple spots of the table as seen fit. Hope this helps (:

Excepting groups 5-12 of the periodic table.the atomic radius increase down in the group.
Yes, there are clear patterns in the periodic table known as periodic trends. These include trends in atomic size, ionization energy, electronegativity, and chemical reactivity as you move across and down the table. These trends are a result of the periodicity in the elements' electronic configurations.
CPI stands for Continuous Plating Index. It is a measure used in electrochemistry to determine the ability of a metal to plate out of a solution onto a cathode. It helps predict the likelihood of a metal depositing onto a surface during plating processes.
