All Activities Class 9 Science Chapter 4 Atomic Structure
In this post, you will learn all activities of chapter
4 atomic structure. It consists of activities 4.1 and 4.2 in class 9 science.
Activity 4.1 Class 9 Science
· Comb
dry hair. does the comb then attract a small piece of paper?
· Rub
a glass rod with a silk cloth and bring the rod near an inflated balloon.
· Observe
what happens.
Observation Activity 4.1 Class 9 Science
The small piece of paper will be attracted to the
comb.
The inflated balloon will be attracted towards the
comb.
Explanation Activity 4.1 Class 9 Science
Initially, the comb is neutral but when we comb dry hair,
it gets charged so charged comb attracts a piece of paper.
When a glass rod is rubbed with a silk cloth, it gets
charged and this charged rod attracts an inflated balloon.
Conclusion Activity 4.1 Class 9 Science
Through Activity 4.1 Class 9 Science we can conclude
that when two objects are rubbed together, they become electrically charged. The opposite charge attracts each other.
Activity 4.2 Class 9 Science
· Make
a static atomic model displaying the electronic configuration of the first eighteen
elements.
Solution Activity 4.2 Class 9 Science
.webp "a static atomic model displaying the electronic configuration of the first eighteen elements.")
Conclusion Activity 4.2 Class 9 Science
So above are the atomic models displaying the electronic configuration of the first eighteen elements.
