Match each term with its label on the diagram.

How can any of the items you labeled in Question 7 be used to learn more about the basic structure of an atom?

Required

2

Select the statements that describe how electrons are arranged in an atom

Required

2

Elements with similar chemical and physical properties are also placed together within _______ or families. (vertical columns). The _______ (or row) number indicates the number of electron energy levels in an atom of that element.

There are many versions of the periodic table that include slightly different information. The designations for the groups, for example, are presented in three main styles. The European and U.S. conventions use “A” and “B” labels for different parts of the periodic table. In the U.S. model, the “_______ ” groups include the “main group elements” in columns 1, 2, and _______ . These are often called the "representative elements." The “B” groups are the transition metals. The International Union of Pure and Applied Chemistry (IUPAC), a worldwide organization working to standardize chemistry conventions, simply numbers the groups 1–18.

Required

1

Elements that appear in certain places on the periodic table exhibit _______  properties.

Required

3

Metals are located on the _______ -hand side of the periodic table. Metals are primarily in Groups 1-12. Some elements in Groups 13, 14, and 15 are also metals. Metals exhibit similar properties. They have _______  melting points. Melting point is the temperature at which a solid substance transforms into a _______ . Metals are usually solid at room temperature because of this property. Mercury is a highly toxic metal. It is one of only two elements that exist in the liquid state at room temperature.

Valence electrons are an important factor in determining the properties of an element. Valence electrons are those that atoms tend to gain, lose, or share during a chemical reaction. 
For representative elements, they are electrons in the outer energy level. Elements in Group 1 contain one valence electron. Elements in Group 2 contain two valence electrons. For elements in Group 13-18, the number of valence electrons is 10 less than the group number. An element in Group 15, for example, has 5 valence electrons. Helium is an exception to this rule, as it is located in Group 18, but has 2 valence electrons. The elements in Groups 3-12 have varying numbers of valence electrons.

For elements in Group 13-18, the number of valence electrons is 10 less than the group number. An element in Group 15, for example, has __________valence electrons. Helium is an exception to this rule, as it is located in Group 18, but has __________ valence electrons. The elements in Groups 3-12 have varying numbers of valence electrons.
