Atomic radii increase when going down a group and decreases when going towards the anion periods. So A and D.
Given :
The distance between a point charge and a neutral atom and is multiplied by a factor of 5.
To Find :
By what factor does the force on the neutral atom by the point charge change.
Solution :
We know, electrostatic force between two object is directly proportional to product of charge and inversely proportional to distance between them.
Now, charge in neutral atom is 0 C.
So, the electrostatic force between two of them is also 0 N.
Therefore, by changing distance between the charge the forces did no change ( it remains zero).
Answer:
A
Explanation:
liquids thake the shape of what holds them so shape is changing and volume is the same
Cytokinesis and telophase!
B
A qualitative observation describes the characteristics of a substance without quantifying them.
