C2 - Ionic Bonds

Question 1

Ionic bonds

Answer 1

• ionic bonding involves an attraction between oppositely charged ions
• inonc bonds are found in compounds made in metals and non-metals

Question 2

Covalent bonding

Answer 2

• involving 2 atoms sharing 1 or more pairs of electrons

- covalent bonds are found in most non-metal elements and in compounds of non-metals

Question 3

Metallic bonding

Answer 3

• Metallic bonding involves an attractions between positviely charged ions and negativliely charged, delocalised electrons
• Metallic bonds are found in metalic elements and alloys

Question 4

Group 1 metals

Answer 4

Form positive ions with a single positive charge

Question 5

Groups 2 metals

Answer 5

Formpositive ions with a double positive charge

Question 6

Group 6 non-metals

Answer 6

From negative ions with a double negative charge

Question 7

Group 7 non-metals

Answer 7

Form negative ions with a signle negative charge

Question 8

Noble gases

Answer 8

Not usually involved in ionic bonding

Question 9

What type of boding happens between monst non-metal elements

Answer 9

Covalent bonding

Question 10

Positive ions (cations)

Answer 10

• Positive ions are usually created when an atom or molecule loses electrons
• The metals in group 1 & 2 can easily lose electrons to become positively charged ions

Question 11

Negative ion (anions)

Answer 11

• Negastive ions are usually created when an atom or molecule gains electrons
• The non-metals in group 7 are most likely to gain electrons to fill up their electrons shell and become negatively charged

Question 12

Ions containing multiple elements

Answer 12

Either:

• Single elements (e.g. F-)
• A group of elemtns with an overall charge (e.g. SO4^2-)

Question 13

Positive ions

Answer 13

Usually created when an atom or molucule loses electrons

Question 14

Negative ions

Answer 14

Negative ions are usually when an atom or molecule gains electrons
