bonding

Question 1

when does an ionic bond occur?

Answer 1

between metals and non metals

Question 2

when does a covalent bond occur?

Answer 2

between non metals

Question 3

when does a dative covalent bond occur?

Answer 3

involves lone pair of electrons

Question 4

when does a metallic bond occur?

Answer 4

between metals

Question 5

define an ionic bond

Answer 5

a strong electrostatic force of attraction between oppositely charged ions

Question 6

what is a giant ionic lattice?

Answer 6

structures of positively charged and negatively charged ions with strong electrostatic forces of attraction

Question 7

what is the ionic bonding general rule?

Answer 7

if an element from group 1,2 or 3 reacts with an element in group 6 or 7 then the bonding is ionic

Question 8

what is a dative covalent bond?

Answer 8

covalent bonds which are formed when both electrons are donated by only one of the atoms in the bond

Question 9

what is a metallic bond?

Answer 9

a strong electrostatic force of attraction between the delocalised sea of electrons and positive ions

Question 10

what are the properties of a metallic bond?

Answer 10

conduct heat and electricity because the delocalised electrons are free to move, high mp and bp as they require lots of energy to overcome

Question 11

what are the lines in O=O

Answer 11

each line represents a pair of shared electrons
