Laws Of Electrostatic Forces

Question 1

Basics

Answer 1

1. Like charges repel
2. Opposite charges attract
3. The greater the distance between charges, the less force between them
4. The greater the charge, the greater the force

Question 2

Atomic Number

Answer 2

Increases from left to right and top to bottom
= protons increase from left to right
= amount of charge increases
Doesn’t mean nucleus gets bigger or closer to shells.

Question 3

Atomic Radius

Answer 3

Size of the atom
Decreases from left to right
Increases from top to bottom

Question 4

Ionization Energy

Answer 4

Amount of energy required to remove electrons from an atom to make a positive one.
Increases from left to right
Decreases from top to bottom
(Same as Electronegativity)

Question 5

Electronegativity

Answer 5

Tendency of an atom to attract the electrons of another atom (in data book)
Generally, it increases from left to right
Generally, it increases from top to bottom
