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?
Select the statements that describe how electrons are arranged in an atom
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.
Valence electrons are not an important factor in determining the properties of an element.

|---|---|---|
calcium | arrow_right_alt | Elements in this group are very stable gases at room temperature |
argon | arrow_right_alt | Elements in this group are soft metals that can be cut with a butter knife and react violently with water to form strong bases |
bromine | arrow_right_alt | elements in this group are fairly reactive. They react with water to form weak bases. |
Lithium | arrow_right_alt | elements in this group are highly reactive nonmetals. At room temperature, the elements in this group with lower atomic numbers are gases, whereas the heavier ones are in a liquid and solid forms. |
The atomic structure of the transition metals allows not only electrons from the valence shell to participate in bonding but also what?
This series is part of period 7 on the periodic table, with most of its unstable elements synthesized in a laboratory and all its elements are radioactive.
