B. Short answer
What does an atom become when it gains
or loses an electron?
Which family of elements is the most stable?
Look at the block of atoms as found in
the periodic table (on p 202 of the packet). Which of the elements
is most reactive and why?
If an atom gains two electrons, what is
the charge of the resulting ion?
What chemical characteristic do elements
in a family share?
Why do alkali metals become more reactive
as you move down the periodic table?
Explain why the noble gases do not react
readily with other elements.
