A radioactive Sr is dangerous to
humans because it builds up in the
bone marrow. How does this relate
to the periodic table?
• Sr and Ca are in the same group so they are
similar to each other
• Sr has 18 extra electrons to cause harm
• Sr and Ca are in the same period so are similar
to each other
• Sr is twice as massive as Calcium

• More mass means more protons, which
act to pull electrons closer
• More massive atoms have greater
numbers of shells

Are You Ready?
• Feel free to practice this again and again.
• Please note that if a questions asks about
oxygen on the practice test…the REAL
TEST might ask about another element. It
is important you know why the answer is
right
• Good Luck!
