Interpretation:
To indicate whether Statement I and Statement II are true or false.
Concept introduction:
Boron is an element which belongs to group 13 in the periodic table. The outermost electrons has 3 electrons thus, it can form B3+ ion. The
Answer to Problem 17STP
Statement I and Statement II are true and statement II is a correct explanation of Statement I.
Explanation of Solution
Reason for true statements: The atomic number of Boron is 5. The given figure shows Boron-10 and Boron-11 that are the main isotopes of Boron, thus statement-1 is true. Isotopes have the same number of protons but different number of neutrons, thus statement II is also true.
Boron 10 and Boron-11 are the isotopes of Boron-5, where 10 and 11 are the
Both the statements are true and statement II is the correct explanation for statement I.
