Which of the following correctly compares the radii of f and f−? f has a smaller radius than f− because an additional electron causes greater repulsion in f−. f has a larger radius than f− because an additional electron causes greater repulsion in f. f has a smaller radius than f− because f− has an additional energy shell. f has a larger radius than f− because f has an additional energy shell.

the number of valence electrons for each molecule or ion is shown beneath the structure. remember hydrogen will not have more than two electrons. this hydrogen is part of a covalent bond (sharing two electrons). a double bond here would cause hydrogen to share four electrons with phosphorus.

hloride, what is the mass of calcium in

explanation:

> b takes place in the gas phase in an isothermal tubular reactor. the feed is one mole of a per one mole of c, an inert. the entering temperature and pressure are 427°c and 10 atm, respectively. the gas constant r = 0.08206 atm · l/mol · k.
