Question:
Which of the following statement is incorrect about beryllium?
Which of the following statement is incorrect about beryllium?
Show Hint
Beryllium is small and commonly shows coordination number 4, not 6.
Updated On: Apr 29, 2026
- Beryllium hydroxide is amphoteric.
- Beryllium compounds are largely covalent.
- Beryllium is not easily attacked by acids.
- Beryllium exhibits coordination number of six.
- Beryllium hydroxide dissolves in excess of alkali to give a beryllate ion.
Show Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Concept:
Beryllium is small in size and usually shows a maximum coordination number of 4. It does not generally show coordination number 6.
Step 1: Check true properties of beryllium.
Beryllium hydroxide is amphoteric and dissolves in excess alkali to form beryllate ion.
Step 2: Check covalent nature.
Due to small size and high polarizing power, beryllium compounds are largely covalent.
Step 3: Find the incorrect statement.
The statement that beryllium exhibits coordination number 6 is incorrect.
Step 1: Check true properties of beryllium.
Beryllium hydroxide is amphoteric and dissolves in excess alkali to form beryllate ion.
Step 2: Check covalent nature.
