3. What is the best explanation for the decrease in first ionization
energy moving from Be to B?
(A) Moving from Be to B, more electrons are added to the
atoms, thus increasing the electron-electron repulsions.
(B) Moving from Be to B, more protons in the nucleus
attract the valence electrons, making it harder to remove
the electrons.
(C) The electrons in Be are being removed from a full sub-
shell, which is more stable than the half-filled subshell
in B.
(D) The electrons in Be are located in the 2s subshell. These
electrons penetrate closer to the nucleus than the 2p
electrons in B.

In november 1987, a massive iceberg broke loose from the antartic ice mass and floated free in the ocean. the chunk of ice was estimated to be 98 mi long, 25 mi wide, and 750 ft thick. a typical backyard swimming pool contains about 24,000 gallons of water. how many of these pools could you fill from the water in this iceberg? (assume the iceberg is a rectangular solid of the above dimensions and consists of water only). express answer in scientific notation.
