Question

(a) write the electron dot structure for sodium magnesium and oxygen?(b)show the formation of MgO by transfer of electrons.​

Answer 1

Answer:

(i) The representation of elements with valence electrons as dots around the elements is referred to as electron-dot structure for elements.

Electronic configuration of Sodium (Na)→2,8,1

Electron dot structure =

Na

Electronic configuration of Oxygen (O)→2,6

Electron dot structure =∙

∙

Electronic configuration of Magnesium (Mg)→2,8,2

Electron dot structure =

Mg

(ii) Ionic compounds have strong electrostatic forces of attraction between the ions. It requires a lot of energy to overcome these forces. Thus ionic compounds have high melting points.
