4. This type of element is mostly dull and a poor conductor of electricity and heat.
5. This is the only metal that is liquid at room temperature.
6. The particles in this state of matter are packed closely but not in fixed position.
10. In periodic table, properties of elements arranged in this horizontal row gradually changed from metals to non-metals.
11. few drops of this can be used to demonstrate diffusion throughout the water in a beaker.
16. This model of matter can be used to describe the arrangement and behaviour of particles in different states of matter.
