AS Level Chemistry - Unit 3.1 Electronegativity and bonding

**This Powerpoint specifically uses the Cambridge AS Level Chemistry Syllabus (9701) and covers all criteria for – Unit 3.1 Electronegativity and bonding
**

Students will be able to -
1 define electronegativity as the power of an atom to attract electrons to itself

2 explain the factors influencing the electronegativities of the elements in terms of nuclear charge, atomic radius and shielding by inner shells and sub-shells

3 state and explain the trends in electronegativity across a period and down a group of the Periodic Table

4 use the differences in Pauling electronegativity values to predict the formation of ionic and covalent bonds (the presence of covalent character in some ionic compounds will not be assessed) (Pauling electronegativity values will be given where necessary)

**Every Powerpoint includes learning objectives, a starter and plenary, suitable activities and review questions with mark scheme. We also provide a free pdf version of the file so it can easily be printed for students as a handout or uploaded to the school VLE system
