Problem 39E

Write the Lewis symbols that represent the ions in each ionic compound.

a. NaF

b. CaO

c. SrBr2

d. K2O

Step-by-Step Solution:

Step-by-step solution Step 1 of 4 Letter a) Na belongs to I A group, thus it has one electron in its outer shell F belongs to VII A group thus it has seven electron in its outer shell. Because of the Fluorine’s high electronegativity respect to Na, Fluorine can gain an electron from sodium, thus completing its valence shell and acquiring a negative charge. On the other hand, Sodium acquires a positive charge because it loses an electron, thus the Lewis formula is Step 2 of 4 Letter b) Calcium (Ca) belongs to II A group, thus it has two electrons in its outer shell Oxygen (O) belongs to VI A group thus it has six electron in its outer shell. Because of the Oxygen’s high electronegativity respect to Ca, Oxygen can gain two electrons from Calcium, thus completing its valence shell and acquiring a double negative charge. On the other hand, Calcium acquires a double positive charge because it loses an electron, thus the Lewis formula is
