Question

(1) write the electron dot structure for sodium, oxygen, chlorine and magnesium. Show the formation na2o and mgo by the transfer of electron
(2) name the ions present in these compound.​

Answer 1

Answer:

1)Solution:

When the valence electrons are represented as dots circling the elements, it is known as the

elemental structure with electron dot structure of that element.

(i) Electron Dot Structure:

• Sodium (2, 8, 1) = one electron at the top of Na.

• Oxygen (2, 6) = O two electrons each on three sides of O.

• Magnesium (2, 8, 2) = two electrons on the top of Mg.

The ions present in Na2O are sodium ions 2Na+ and oxide ion O2-. The ions present in MgO are magnesium ion Mg2+ and oxide ion O2-.
