Question

show by graph.I.E, Atomic radii, Melting point of S, p and d block elements differ

Answer 1

Answer:

pls answer is steps and yeah it should be correct all the steps and correct answer would be marked as brainliest

Explanation:

) There are 4 boys and 3 girls. If

the group of two is to be formed,

then the number of sample points

are

(A) 21

(B) 12

(C) 18

(D) 15\bold{\green{✓✓✓✓✓✓✓✓✓}}✓✓✓✓✓✓✓✓✓

\bold{\red{Hope\:it\:will\:help\:you\:}}— 2(x-3) + 3(x+1) = 5(2x-1)Heya!!!

\bold{\blue{Here\:is\:your\: answer\: }}Hereisyouranswer

2(x-3)+3(x+1)=5(2x-1)

2x-6+3x+3=10x-5

5x-3=10x-5

10x-5x= 5-3

5x= 2

x=2/5 . Ans

\bold{\green{✓✓✓✓✓✓✓✓✓}}✓✓✓✓✓✓✓✓✓

\bold{\red{Hope\:it\:will\:help\:you\:}}Hopeitwillhelpyou

\bold{\blue{Here\:is\:your\: answer\: }the number is from zero.

Trends Of Atomic Radii , Melting Point and Ionization Energy

Atomic Radii:  

For S-Block elements:

As For s-block elements we have alkali metals and alkaline earth metals.

The atomic radii of these elements increase down the group as moving down the group the number of shells increase.

For P-Block elements:

The atomic radii of the atoms do not increase regularly on descending the group. There is a large difference between the size of Boron and Aluminium results in many difference in properties.

For D-Block elements:

The atomic radii(covalent radii) decrease from left to right across a row in the transition series, until near the end when size increases slightly.

Atoms of transition elements are small in size as compared to Group 1 and Group 2.

Melting Point:

For S-Block:

We have low values of M.P and B.P for s block elements because of low values of cohesive energy. As cohesive energy decreases down the group so the value of M.P also decreases.

For P-Block:

M.P of P block elements do not shows a regular trend as the s block elements. For p block M.P shows irregular trend.

For D-Block:

The M.P of d block elements are generally high but there is not any regular trend.

Ionization Energy:

For S-Block:

The ionization energy decreases as the size of atoms increases, hence for s block elements value of ionization energy decreases down the group.

For P-Block elements:

The value of ionization energy increases on moving from left toe right and decreases down the group.

For D-Block elements:

The value of ionization energy do not shows a regular trend. Graph will nicely explain the trend of ionization energy.
