GK QUESTION#3311
Consider the following statements about Group 0 elements in the modern periodic table:
1. Group 0 elements are commonly referred to as inert gases due to their low chemical reactivity.
2. These elements have completely filled outermost electron shells, making them highly stable.
3. Group 0 elements include hydrogen and helium, which are highly reactive.
Which of the above statements is/are correct?
Show Answer
Answer
A. Only 1 and 2
Show Explanation
Explanation
The traditional Group 0 family is now called Group 18, the noble gases. Its familiar members have closed outer electron shells and low chemical reactivity, supporting statements 1 and 2. Hydrogen is not a noble gas, and helium is not highly reactive, so statement 3 is false.
