Chemistry Structure And Bonding

Question 1

Ionic bonding is between?

Answer 1

Metal ( group 1 or 2 ) 
Non metal ( group 6 or 7 )

Question 2

How do you draw a dot and cross diagram of ionic bonding?

Answer 2

Atom that electron has been taken from in brackets with the ➕ charge on the outside
Atom that has gained the electron has outer shell drawn showing 7 of the own electron plus the other electron in which is the other shape. This is in brackets and the ➖ charge is on the outside of the brackets

Question 3

Anions are positive or negative?

Answer 3

Negative

Question 4

Cations are positive or negative?

Answer 4

Positive

Question 5

what structure does an ionic compound have?

Answer 5

Giant ionic lattice

Question 6

What is the melting point of an ionic compound? Why?

Answer 6

Very high melting point

A large amount of energy is required to overcome the string electrostatic attractions And separate the ions

Question 7

What is the strength of an ionic compound? Why?

Answer 7

Very brittle

String ionic bond held together in a giant ionic lattice

Question 8

Electrical conductivity of an ionic compound? Why?

Answer 8

Do not conduct when solid because ions cannot move as they are in a fixed position
Conducts when molten or when in an aqueous solution because the ions are now mobile

Question 9

What is the solubility of an ionic compound? Why?

Answer 9

Insoluble in non polar solution but soluble in water because water makes a permanent dipole

Question 10

Charge in ammonium

Answer 10

NH4⃣^➕

Question 11

Charge on hydroxide ion

Answer 11

OH^-

Question 12

Charge on nitrate ion

Answer 12

NO3⃣^-

Question 13

Charge on sulphate ion

Answer 13

SO4⃣^2-

Question 14

Charge on carbonate ion

Answer 14

CO3⃣^2-

Question 15

What structure do atoms held together by metallic bonding have?

Answer 15

Giant metallic lattice

Question 16

What does this type of bonding hold together

Answer 16

Metals
