2.3 Study Guide

Question 1

What happens with electrons during polar covalent bonds

Answer 1

They are shared unequally

Question 2

What happens with electrons during non polar covalent bonds

Answer 2

They are shared equally

Question 3

What happens with electrons during ionic bonds

Answer 3

They transfer electrons from a nonmetal to a metal

Question 4

What is the difference between Ionic and Covalent bonds

Answer 4

Ionic is between a metal and nonmetal and Covalent is between 2 nonmetals

Question 5

What is the difference between non polar and polar bonds

Answer 5

Non polar bonds the electrons are shared equally and both the ends are the same. Polar bonds the electrons are shared unequally and the ends are opposites.

Question 6

Define electronegativity

Answer 6

the tendency for an atom of a given chemical element to attract shared electrons when forming a chemical bond

Question 7

how does electronegativity determine what type of bond two atoms will form

Answer 7

The atom with the higher electronegativity will attract the shared electrons more strongly.

Question 8

How do ionic compounds react in water

Answer 8

All the molecules split apart and bounce around

Question 9

How do covalent compounds react in water (i.e sugar)

Answer 9

The molecules stay together and bounce around

Question 10

What compound had the highest electronegativity
