1.Fluorine can form either covalent or ionic bonds.a.Draw a 'dot and cross' diagram to show the bonding in the following. yourdiagram must show all the electrons. [4](i)sodium fluoride, NaF

Sketch, on paper, the Lewis structure of F2, remembering to:Step 1: Arrange the atomsStep 2: Count the number of valence electrons.Step 3: Allocate two electrons between each pair of atoms which are assumed to be covalently bound.Step 4: Use the remaining valence electrons to form lone pairs, and/or double and triple bonds.What is the total number of valence electrons in F2?What type of bond exists between the two fluorine atoms?How many lone pairs are there on each fluorine atom?

Identify the types of elements that form ionic bonds.

Identify the bonding in the following compounds :1.Potassium fluoride (KF)2.Calcium oxide (CaO)3.Bromine (Br2)4.Oxygen (O2)5.Ethanol (C2H5OH)

Complete the table below by writing the symbols for the cation and anion that make up each ionic compound. The first row has been completed for you.ionic compound cation anionNaCl Na+ Cl−MnF2 FeNO33 NH4Cl CoOH2

In the reaction between a hydrogen ion and a fluoride ion to form hydrogen fluoride, the hydrogen ion is an electron-pair and the fluoride ion is an electron-pair
