1.	Iii. Identify the element in the following figure.a. Oxygenb. Nitrogenc. Hydrogend. Sodium
Answer» Answer: Sodium is an element rater than other Oxygen, Nitrogen and Hydrogen are gases. So, the correct answer is d (Sodium). An element is a thing which contains all the altoms of same charge with all same PHYSICAL properties. These properties includes density, MELTING point and BOILING point. Sodium is a soft metal which is CUT by the knife. It is most reactive and it can REACT when it gets contact with oxygen. So, we kept sodium in oil dipped containers because it does not gets react with oxygen surroundings.
