Two patterns that occur in the Periodic Table are: Electronegativity increases from the left of a period to the right and from the bottom of a group to the top. Atomic radius increases from the right of a period to the left and from the top of a period to the bottom.

There are more elements and it's organized differently
What does Ai mean on periodic table?
"Ai" is not a standard element symbol on the periodic table. It may be a typo or error. The periodic table typically uses two-letter symbols to represent elements, such as "Al" for aluminum or "Ag" for silver.
Why are two of the rows of the periodic table deprecated from the rest of the chart?
The two rows at the bottom of the periodic table, known as the f-block, are separated to conserve space. They contain the lanthanides and actinides series of elements and would make the rest of the periodic table too wide if included. These rows are still part of the periodic table, but they are usually shown below as a separate section for convenience.
Is stainless steel on the periodic table?
Stainless steel is not found on the periodic table. It is a metal alloy made from a combination of iron, carbon, and other elements such as chromium and nickel. These elements are found on the periodic table.
What two elements in the periodic table end in y?

Which can be found on a periodic table elements compounds or mixtures?
Elements are found on periodic table. Compounds are not present on periodic table. The table does not contains mixture.Elements can be found on a periodic table. Compounds can be made by bonding two or more elements. But they are not depicted on the periodic table.
Where does the periodic table become wider?
In the modern day periodic table, the periodic table gets wider in periods two, four, and six.
What are the two names for horizontal rows on the periodic table?
The two names for horizontal rows on the periodic table are periods and series.
Why were element gallium and germanium important to mendeleev?
Gallium and germanium were important to Mendeleev because their properties fit well into his periodic table, filling the gaps he had predicted based on the patterns of other elements. The discovery and confirmation of these two elements helped validate his periodic law and strengthen his periodic table's credibility.
Which minerals on the periodic table is made up of two elements?

What is H2S on the periodic table?
You will not find H2S on the periodic table. The periodic table contains only elements, and H2S is a compound, made of two elements, hydrogen (H) and sulfur (S).
Why is water not found in periodic table?
Water is a COMPOUND of two(2) elements, viz. Hydrogen(H) and Oxygen(O). These tqo elements are both found in the Periodic Table. The Periodic Table is a list of ELEMENTS, not compounds.
Does the periodic table explain the shell model or does the shell model explain the periodic table?
The shell model explains the organization of the periodic table. The elements in the first period have electrons in the first shell; the elements in the second period have electrons in the first two shells; the elements in the third period have electrons in the first three shells; and so on.
