Total questions: 12
Worksheet time: 6mins
Which from following is example of dative bond formation?
Potassium ion
Aluminum ion
Hydroxonium ion
Chlorium ion
What is the basis of a metallic bond?
the attraction of neutral metal atoms.
the attraction between protons and neutrons.
the attraction between positive metal ions and interlocking electrons.
the attraction between positive metal ions and free moving electrons.
Why do metals conduct electricity?
They are shiny
The electrons are delocalised and able to move
The electrons are held tightly within the lattice
The electrons are shared between two metal ions
How do covalent bonds form?
Donating & receiving valence e- between atoms.
Opposite slight charges attract each other between compounds.
Scientists are still not sure how they form.
Sharing valence electron between atoms.
NaBr
H2O
How is covalent bonding represented?
by writing its valence electrons
by writing its Lewis structure
by writing its number of bonds
by writing its number of protons
which of the following is false about ionic compounds?
not soluble in organic solvents
soluble in water
low melting and boiling points
conduct electricity in a molten state or aqueous solution
name the bond that exist between water molecules
metallic bond
hydrogen bond
dative bond
delocalised electrons means
free electrons are not held by any metal ions or atoms
electron pair that is shared comes from one atom only
sharing of the electrons between two non-metal atoms
