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

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 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.
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.
What are the elements in the tall columns of the periodic table called?
Representative elements
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.
