Question 1

Ionic Bond

Answer 1

formed by the transfer of electrons between a metal atom and a non-metal atom

Question 2

strategy to tackle chemical bonds q

Answer 2

write electron arrangement
decide bond
predict formula
draw diagram
explain in detail

Question 3

Why the difference in melting and boilling points

Answer 3

ionic
oppositely charged ions are attracted to each other by strong electrostatic force
a lot of heat is required to overcome force of attraction

covalent
molecules attracted by weak van der waals force
little heat required to overcome force of attraction

Question 4

Hydrogen Bond

Answer 4

attraction forces between hydrogen atom, H that has bonded with an atom of high electronegativity, such as nitrogen, N, oxygen, O or fluorine, F with nitrogen, N, oxygen, O or fluorine, F in another molecule.

Question 5

Dative Bond

Answer 5

type of covalent bond where the electron pair that is shared comes from one atom only.

Question 6

Metallic Bond

Answer 6

electrostatic force between sea of delocalised electrons and positively charged metal ions
