The vertical "groups" group elements by chemical properties the horizontal "periods" group elements by the number of energy levels
all the elemants have valence electrons the last number of the elecotrons is the elemets valence electrons
There were around 52 known elements in the periodic table in 1834. The periodic table was still in its early stages of development during this time, and many elements were discovered and added to the table in the years that followed.
P block elements are not called transition elements because they do not have partially filled d subshells in their ground state electronic configuration. Transition elements are defined as those elements that have partially filled d subshells, which allows them to exhibit characteristics such as variable oxidation states and the formation of colored compounds. P block elements, on the other hand, have their valence electrons in the p subshell.
At Room Tempeture, Metals contain the most Elemants.
In the periodic table, the elements are arranged by atomic number
the elements in h2o are two hydrogen particles and one oxygen particles. hydrogen and oxygen are both elements.
The elements in the first two groups and in the last 6 groups. Basically all the elements except the inner transition and transition elements.

Those gases are called noble gases. They are i the 18th group of the periodic table.
chemically combined elemets
Elements that do not react with other elements are typically found in the noble gases group, located in Group 18 of the periodic table. These elements have full outer electron shells, making them stable and unlikely to form chemical bonds with other elements.

Carbon
Groups 1-12 are metals 1-2 are the alkaline and alkaline earth metals, 3-12 are the transistion mrtals and.13-18 are nonmetals.
