Question

how do the following change?
(1) number of shells of elements as we go down group
(2) number of valence electrons of elements on moving from left to right in a period
(3) atomic radius in moving from left to right in a period.
(4) atomic size down a group.

Answer 1

__________________________________________________________

°. (1) number of shells of elements while going down a group increases by 1.

°. (2) The valence electrons increase in number as you go across a period. Then when you start the new period, the number drops back down to one and starts increasing again.

° (3) generally, atomic radius while moving from left to right in a period decreases.

° (4) atomic size while moving down a group increases due to increase in number of shell.

Hope it will help you...✌️✌️

Answer 2

1)As we go down in periodic table SHELLS INCREASES.

2)As we move from left to right

THE SEQUENCE IS

1,0,1,2,3,4,3,2,1,0,1,2,3,4,3,2,1,0

It depends on valence electrons.

3)If we go from left to right ATOMIC SIZE DECREASES.

4)If we go from up to down ATOMIC SIZE INCREASES.
