Match List I (Atomic number of element) with List II (Block to which the Element belongs) and select the correct answers using the codes given below.
List 1 List II
(Atomic number of element) (Block to which the element belongs)
List 1 | List 2 |
---|---|
24 | P |
38 | F |
49 | S |
59 | D |
Solution
We know that in the periodic table there are several elements present. We can classify these elements as metals, non-metals, and metalloids. We can find the metals in the extreme right side of the periodic table, the non-metals are found in the left side of the periodic table and a thin line separates certain nonmetals and metalloids.
Complete answer:
We are given with table below,
List 1 | List 2 |
---|---|
24 | P |
38 | F |
49 | S |
59 | D |
We are provided with two columns in the table given. In the table, the first column contains the atomic number of elements and the second column contains blocks in which the elements are found.
We know that in the periodic table, there are four blocks and these blocks are classified as s, p, d, and f blocks. We have to know that the alkali and alkali earth metals are found in the s-block of the periodic table, the p-block contains the non-metals and the d-block contains transition metals, and the f-block has actinides and lanthanides.
So, now we shall identify the elements from their atomic number.
The given atomic number is 24 . From the periodic table, we have identified the element which has atomic number 24 as chromium. Chromium is a transition metal. Transition metals are found in d-block. So, the atomic number 24 belongs to d-block.
The given atomic number is 38 . From the periodic table, we have identified the element which has atomic number 38 as strontium. Strontium is an alkaline earth metal. Alkaline earth metals are found in s-block. So, atomic number 38 belongs to s-block.
The given atomic number is 49 . From the periodic table, we have identified the element which has atomic number 49 as indium. Indium is a non-metal. Non-metals are found in p-block. So, the atomic number 49 belongs to p-block.
The given atomic number is 59 . From the periodic table, we have identified the element which has atomic number 59 as praseodymium. Praseodymium is a lanthanide. Lanthanides are found in p-block. So, the atomic number 59 belongs to f-block.
We can give matched table as,
List 1 | List 2 |
---|---|
24 | P |
38 | F |
49 | S |
59 | D |
Note:
We can find the elements of s-block on the left side of the periodic table, the right-side of the periodic table will have the elements of p-block. Transition metals come under the d-block of the periodic table and f-block elements have inner transition metals. D-block elements will be found in the middle of the periodic table and f-block elements will be found in the bottom of the periodic table.
