Which of the following statements best describes the elements in family 16 of the Periodic Table?

Elements in a group on the periodic table are described below:

* Diatomic molecules              * Salt formers             * 7 valence electrons               * Nonmetals 

Elements in a group on the periodic table are described below:

* Fairly non-reactive             * Nonflammable            * Charge of 0          * Complete valence shell

The periodic table is first arranged by

Each column in the periodic table is called a                  , while each row in the periodic table is called a                        .

Match the following elements with their correct group.

Match the following element groupings with their correct description.

Some students conducted a laboratory investigation to learn more about the physical properties of different elements. They observed four samples and recorded their observations in the table . Based on these observations, which sample is most likely a nonmetal?

Which particles determine the atomic number and identity of an element?

To get the atomic mass you must
