Bonding

Question 1

Types of primary chemical bonds

Answer 1

Ionic
Covalent
Metallic

Question 2

Ionic bonds

Answer 2

Physical exchange of an electron from the valence shell of one atom to the valence shell of another atom
Charged ions from an attraction

Question 3

Cations

Answer 3

Positively charged ions

Question 4

Anions

Answer 4

Negatively charged ions

Question 5

Covalent bonds

Answer 5

A bond formed by sharing one or more pairs of electrons between the valence shells of two atoms

Question 6

Non polar covalent bonds

Answer 6

Occur when the resulting molecule has no charge associated with in

Question 7

Polar covalent bonds

Answer 7

Occur when the sharing of electrons is uneven e.g water

Question 8

Metallic bond

Answer 8

The electrostatic interactions between electrons and cations

Positive metal ions held together by a sea of negative electrons

Question 9

Hydrogen Bonding

Answer 9

A special type of dipole-dipole attraction that results from a hydrogen atom covalently bonded to a very electronegative atom e.g N,O or F

Question 10

How hydrogen bonding works

Answer 10

attraction to the slightly positive and slightly negative side of a molecule keeps them together

Question 11

Chemical reactions

Answer 11

Bonds that hold atoms together are broken and rearranged to make new substances

Question 12

Reactants

Answer 12

Molecules at the start of a reaction

Question 13

Products

Answer 13

Molecules at the end of a reaction
