Chapter 6, Problem 44A

Interpretation Introduction

Interpretation:

The four blocks of the periodic table needs to be explained.

Concept introduction:

Periodic table is the table where elements are arranged using the atomic numbers. The horizontal rows are periods and vertical column are groups of the periodic table. There are 7 periods and 18 groups of the periodic table.

Answer to Problem 44A

The four blocks of the periodic table are s-block, p-block, d-block and f-block.

Explanation of Solution

The periodic table has four blocks, s-block, p-block, d-block and f-block. s-block of the periodic table consists of two groups, group I and II. Group I is also known as alkali metals and group 2 is also known as alkaline earth metals. p-block consists of groups from 13 to 18. The elements of this block are a non-metal, metalloid or noble gas. The d-block consists of groups 3 to 12 and the elements of these groups are transition metals and f-block contains two separated rows below the periodic table and this block contains actinides and lanthanides.

Conclusion

The s-block contains metals, p-block contains non-metals, metalloid and noble gas, d-blocks contains transition metals and f-block contains lanthanides and actinides.
