Why are elements in tall columns of the periodic table called representative elements?
They follow a pattern for valence electrons.

What are elements in a tall columns of the periodic table?
The elements in the tall columns of the periodic table, also known as groups or families, share similar chemical properties due to their comparable valence electron configurations. For example, Group 1 elements, such as lithium and sodium, are alkali metals known for their high reactivity, while Group 17 elements, or halogens, like fluorine and chlorine, are highly electronegative and reactive nonmetals. Each group has distinct characteristics that influence their reactivity, bonding behavior, and overall chemical behavior.
How can you determine the number of valence electron atom has?
Look what column it is in within the Periodic Table. The first column has 1 valance electron. The second column has 2 valence electrons. The entire section of shorter columns (all metals) also have two valence electrons. The tall column after that (with Boron ) has three valence electrons. The tall column after that (with carbon) has four valence electrons. This pattern continues until you reach the final column, the noble gasses (eg. Neon, argon, xenon); these all have 8 valence electrons.
How do you know if a metal is a transitional metal?
go loook at a periodic table. there are 8 tall periods, the middle periods that are shorter then all the rest, after the two first ones, those are the transitional metals.

What are elements in the tall column of the periodic table?
Representative elements
Why are elements in the tall columns in the periodic table called representative elements?
Conventionally representative elements are called the chemical elements from the groups 1,2, 13-18. These elements haven't generally variable valencies. The transitions metals are not representative elements.
What are the elements in the tall columns of the periodic table called?
Representative elements
What are representatives elements?
elements from group1-2 ,13-18 are called representative elements. Those from 3-12 form the transition elements!
Why are two rows of the periodic table taken out?
The two rows at the bottom of the periodic table are taken out to make the table more compact and easier to read. These two rows are known as the lanthanides and actinides series. They are removed and placed below the main table to avoid making the entire table wider than it is tall.
What are the elements in the tall columns called?
The elements in tall columns are called capital, shaft, and base. The capital is the decorative top portion, the shaft is the long vertical section, and the base is the bottom part of the column.
What were the three elements that made up the Pantheon?
The Pantheon was made up of three elements:* a porch with columns; * a tall intermediary block; and * a rotunda that forms the cella of the temple.
