Question

1) write the electron dot structure for sodium, oxygen, magnesium and chlorine. 2) show formation of sodium oxide and magnesium oxide by transfer of electrons. 3) Name the ions present in these compound.

Answer 1

1. The electron dot structure for

• Sodium (NA) – 2, 8, 1

• Oxygen (O) – 2, 6

• magnesium – (MG)- 2, 8,2

• chlorine (CL)- 2,6

2. Magnesium looses 2 electrons to oxygen atom while sodium looses one electron each to oxygen atom.  

3. The ions present in these compound:

• The ions present Na2O are NA+ and O-2

• In MgO ions present are MG+2 and O-2
