26. Use labelled diagrams to clearly show how the trends in atomic radius and electronegativity are related to each other.
Homework Answers
Smaller the atomic number greater the electronegetivity. Electronegetivity decreases as one goes down a group because the atomic radius increases, same thing happened along a period also.If one goes left to right in a period atomic radius decreases and electronegetivity increases.

Draw a labelled diagram showing the atomic orbitals for N and O on each side and the molecular orbitals for NO, in the middle. The diagram should clearly show: which atomic orbitals combine to form each molecular orbital, the relative position (increasing energy going up the page) of the molecular orbitals and the locations of electrons in the atomic orbitals and in the molecular orbitals. Use your diagram to determine the following: What is the bond order? Explain how you...
