As you might expect from the previous section, the octet rule plays a huge role in ionic compound formation. Let's imagine what happens when lithium reacts with chlorine to form an ionic compound. Lithium has very low electronegativity, meaning that it tends not to want electrons.
Chlorine, on the other hand, has a very high electronegativity, meaning that it wants to gain electrons. As a result, lithium gives electrons to chlorine when one atom of each comes into contact with the other. Figure 8. Because the lithium cation and chlorine anion have opposite charges, they attract one another and form lithium chloride, LiCl. Positively charged Lithium ions form an ionic bond with negatively charged Fluoride ions.
They are held together by this strong force of attraction because opposites attract. The opposite charges form an electrostatic attraction which is the ionic bond. When iron oxide is heated with carbon, iron is produced. What would be the word equation for this reaction? What are the key points in recognising if a substance is pure? At Scoodle we understand that everyone learns in a different way. Some people learn through practice, using essays and notes; others prefer video lessons to watch and learn, some just need help with a specifically hard question, while some learn best 1-on-1 tutoring sessions.
At Scoodle we cater for all types of learning styles and needs. Hard-working tutor and graduate student at the University of Oxford.
Friendly and knowledgeable Oxford University student and graduate. Double 1st Class in Physics and Philosophy. Experience in HL Biology. Accomplished tutor and who is ready to teach! I have been tutoring for 3 years in these subjects and many more I like to tutor through games and fun activities I teach ks1 through to GCSE.
Savvy tutor and undergraduate at Imperial College London. Hi I am a fifth year medical student from Imperial College London and I have been a tutor for a number of bespoke tuition agencies. I like to tutor tuition to the needs of the students which results in a high-yield achievement. Hi, I'm Ross! This is marked before the next lesson so we can go through feedback at the start of the next lesson. I find this is more effective in allowing the student to understand the content, rather than just memorising and regurgitating.
Experienced Physics and maths tutor. Ionic bonding in sodium chloride. Ionic bonding in magnesium oxide. Ionic bonding in calcium chloride. Draw a diagram, with outer electrons only, to show how the electrons are transferred when magnesium chloride is formed from its elements.
