a. Their chemical properties are same.

b. Their chemical and physical properties both are same.

c. Their physical properties are same.

d. Cannot say anything about their chemical properties.​

Answer 1

The atomic masses of elements P and Q are 6 and 7 and their atomic number is 3 this signifies that their chemical and physical properties both are the same.

Explanation:

1. The element with the same atomic number possess similar properties.
2. Atomic number and atomic mass tell us the property of the element.
3. The element with atomic mass 6 and 7 possess similar physical and chemical properties.
4. The element name is Lithium (Li).

Answer 2

The atomic masses of element P and Q are 6 and 7 and their atomic number are 3 is Option(b) Their chemical and physical properties both are same.

Explanation:

• The physical and chemical properties depends upon the number of electrons and their electronic configuration.
• The atomic number and atomic mass tell us the property of the element.
• The atomic masses of element P and Q are 6 and 7 and their atomic number are 3 as given in question  has same chemical and physical properties.
