1. For each of the molecules below, determine the electron geometry, molecule geometry, and bond
angles.

a. CC14 (4 Cl atoms, no lone pairs on C)

b. PF3 (3 Fatoms, 1 lone pair on P)

c. OF2 (2 F atoms, 2 lone pairs on O)

d. 13. (2 1 atoms and 3 lone pairs on central I)

e. A molecule has 2 double bonds on the central atom and no lone pairs. Predict the molecule geometry. What do you think the bond angles would be?

Which statement is true about this reaction? 14n+1h 15o it is a practical source of energy on earth. it occurs only outside the solar system. its product is heavier than each of its reactants. it shows the critical mass of an element.

The table compares the number of electrons in two unknown neutral atoms. comparison of electrons atom number of electrons a 9 d 11 use this information to determine the number of valence electrons in the atoms. which of the following correctly compares the stability of tthe table compares the number of electrons in two unknown neutral atoms. comparison of electrons atom number of electrons a 9 d 11 use this information to determine the number of valence electrons in the atoms. which of the following correctly compares the stability of the two atoms? both are unreactive. both are highly reactive. a is unreactive and d is reactive. a is reactive and d is unreactive.

How can the periodic table be used to predict the behavior of elements?
