Understand the classification of elements into metals, nonmetals, and metalloids based on their properties and position in the periodic table.
Recall that metals are typically found on the left and center of the periodic table and are characterized by properties such as good electrical conductivity, malleability, and luster.
Identify the elements given: Ne (neon), Cl (chlorine), O (oxygen), and Na (sodium), and locate them on the periodic table.
Recognize that Ne, Cl, and O are nonmetals: Ne is a noble gas, Cl and O are nonmetallic elements found on the right side of the periodic table.
Note that Na (sodium) is an alkali metal located in Group 1 of the periodic table, which classifies it as a metal.
