Question

(i) Write the electron-dot structures for sodium.
(ii) Show the formation of Na O by the transfer of electron​

Answer 1

Explanation:

1.When the valence electrons are represented as dots circling the elements it is known as the elemental structure with electron –dot. Thus for option i) we can write Sodium (2, 8, 1) = Na with one electron at the top. Again for Oxygen (2, 6) = O with two electrons each on three sides.

2.For the formation of Na2O: It is an ionic compound and sodium has 11 atomic number and oxygen has 8 atomic number. ... Therefore two atom of sodium will combine with one atom of oxygen and each sodium will lose one electron to oxygen and therefore completing its octet.
