A hypothesis is defined as an idea or explanation which is framed without any testing or experimentation.
And, in order to verify the hypothesis we need to perform the experiment. And, on the basis of experimentation we can conclude whether our hypothesis was correct or not.
For example, when we have to perform an experiment to determine which freezes more easily—distilled water or salt water. Then the steps in this experiment should be as follows.
Make a prediction about which liquid will freeze first.
Fill two beakers with 250 mL of distilled water.
Dissolve 30 grams of salt in one of the beakers.
Place both beakers in a freezer and observe which liquid freezes first.
Non metals (It’s both halogens and noble gases ) the other ones which are white(not highlighted) are alkali metals, alkaline earth metals, and transition metals :3
