The three main categories of elements on the Periodic Table are metals, metalloids, and nonmetals.
See the periodic table at the link below.
The three broad classes of elements found the periodic table are metals, non metals, and metalloids.
The main metals in the periodic table are iron, copper, zinc, silver, gold, and platinum. Metals are typically found on the left side of the periodic table and are known for their conductivity, malleability, and luster.
The first three periods of the periodic table are called the first period, second period, and third period.
Non-metals are more or less located in the upper-right quarter segment of the periodic table. The left half and the lower half (about three quarters) of the p.t. are metals.
See the periodic table at the link below.
The three broad classes of elements found the periodic table are metals, non metals, and metalloids.
The three families that are found in the center portion of the periodic table are the Iron group, the Cobalt group and the nickel group. There are 18 families in the periodic table.
NOT as 'diamond'. However, diamond is an allotrope of carbon . Carbon is found in the periodic table. as 'C'. NB Diamond, Graphite and Buckminster Fullerene (Footballene) are three allotrop[es of of Carbom . NOT isotopes. An Allotrope is an element that exists in different physical form.
The three major categories in the Periodic Table are metals, nonmetals, and metalloids. Metals are typically shiny, malleable, and good conductors of heat and electricity. Nonmetals are often dull in appearance and poor conductors of heat and electricity. Metalloids have properties that are intermediate between metals and nonmetals.

Magnesium's period number is 3. It is found in period 3 of the periodic table.
Because those elements were not known when he formulated his periodic table.
The first three periods of the periodic table are called the first period, second period, and third period.

NaCN stands for sodium cyanide. This is a compound and is not found on the periodic table as such. Periodic table is an arrangement of elements and not compounds. NaCN contains three elements: Sodium (Na, atomic number 11), carbon (C, atomic number 6) and nitrogen (atomic number 7).
