explain how the valence configurations of atoms are related to the atom's similarity in reactivity

7.19 If the formation of chemical bonds always releases energy, why don't all elements form dozens of bonds to each atom?

7.46 Consider the nitrogen-oxygen bond lengths in NO2+ , NO2 , and NO3 . In which ion is the bond predicted to be longest? In which is it predicted to be the shortest? Explain briefly.

What aspect of the following Lewis structure indicates that the concept of coordinate covalency is needed to explain the bonding in the molecule?

7.22 Use Lewis dot symbols to explain why chlorine bonds with only one hydrogen atom.

For single bonds between similar types of atoms, how does the strength of the bond relate to the sizes of the atoms? Explain.

How many valence electrons are present in the atom AL?

Part C Bond length is the distance between the centers of two bonded atoms. On the potential energy curve, the bond length is the internuclear distance between the two atoms when the potential energy of the system reaches its lowest value. Consider that the atomic radius (sometimes called the covalent or bonding atomic radius) of an element is defined as one-half the distance between the bonded atoms in a homonuclear diatomic molecule. Actual bond lengths in molecules are determined experimentally by such methods as X-ray diffraction and microwave spectroscopy. However, these atomic radii values can be used to give an estimate of the upper limit of bond length in other (heteronuclear) molecules. Given that the atomic radii of H and F are 37.0 pm and 72.0 pm, respectively, predict the upper limit of the bond length of the HF molecule. Express your answer to three significant figures and include the appropriate units. ► View Available Hint(s) Bond length upper limit= Submit μÅ Value…
