True or False:
ALL covalent compounds are insoluble in water (cannot dissolve in water)
True
False
The illuminati
- 13. Multiple Choice
Why are ionic compounds soluble in water?
reasons
Because the bonds become too weak.
Because the energy given off by the ions touching the water breaks the bonds.
Because the surface tension on the water breaks all the bonds.

- 14. Multiple ChoiceThere are more metals than non metals in the periodic table.TrueFalse
- 15. Multiple ChoiceAt room temperature, most metals areliquidsolidgasan alloy
- 16. Multiple Choice
Why are metals malleable?
They are shiny
The electrons are held tightly within the lattice structure making it strong
The electrons are delocalized and able to move between the atoms
The electrons are shared between two metal ions and this holds the atoms together
- 17. Multiple ChoiceMetals like to ________ electrons.GainLoseAnhilateJuggle
- 18. Multiple ChoiceWhy do metals have high melting points?They don'tThe negatively charged electrons act as a glue to hold the positively charged ions together.All the electrons become delocalised
