Periodic Practice!
Fill in the missing information on the chart about each element using your periodic table.
You may want to do 1-5 at the bottom first if you need help. To determine the number of
neutrons you may need to round off the atomic mass to the nearest whole number.

A column in the periodic table is a _______________ or _________________.
A row is called a _____________________.
I find the atomic number from the number of ___________________.
The number of _________________ is equal to the number of protons in an
uncombined atom.
5. The number of neutrons is found by subtracting the atomic _____________ from
the atomic __________________.

A column in the periodic table is a family or group.
A row is called a period.
I find the atomic number from the number of protons
The number of electrons is equal to the number of protons in an uncombined
atom.
5. The number of neutrons is found by subtracting the atomic number from the
atomic mass.
