Unit 1-(d) Bonding, Structure and Properties-A. Bonding

Question 0

Why do atoms form bonds?

Answer 0

So that they can achieve a stable electron arrangement

Question 1

What holds atoms together?

Answer 1

atoms

Question 2

What happens to electrons in a covalent bond?

Answer 2

they are shared

Question 3

What is the covalent bond a result of?

Answer 3

two positive nuclei being held together by a common attraction for a shared pair of electrons

Question 4

How strong are covalent bonds?

Answer 4

pretty strong

Question 5

What is a polar covalent bond?

Answer 5

When the attraction of the atoms for the bonded electrons is different. The electrons are unequally shared

Question 6

Give an example of a substance with polar covalent bonds…

Answer 6

water

Question 7

When is an ionic compound formed?

Answer 7

when metals combine with non metals.

Question 8

How are positive ions formed?

Answer 8

by metal atoms losing electrons (oxidation)

Question 9

How are negative ions formed?

Answer 9

By non metal atoms gaining electrons (reduction)

Question 10

What is ionic bonding?

Answer 10

The electrostatic force of attraction between oppositely charged ions.

Question 11

What is metallic bonding?

Answer 11

The electrostatic force of attraction between positively charged ions and delocalised electrons.
