Question

correct expression for Na2O crystal is?​

Answer 1

ANSWER

Option 2

$\frac{ \sqrt{3}a}{4} = R(Na^+) + R(O^2-)$

Additional information

• Antiflorute structure
• 8 Na+ , 4O2- => 4:8
• similar compounds :- li2o, li2s, Na2s, k2o, k2s
• number of formula per U. C.C. is (4)

hope it helps

Answer 2

The correct expression for Na2O crystal is √3a / 4 = rNa^+   + rO^2-

Option (B) is correct.

Explanation:

• Sodium Oxide (Na2O) is an ionic compound and it contains two sodiums atoms and one oxygen atom.
• The bond between sodium and oxygen atoms is an ionic bond as the compound is formed by donating electrons.
• It is an odorless and ionic white crystalline compound.
• Sodium oxide is sued for making glass products.
• In crystal form the ratio between sodium and oxygen atoms in 4:8
