In order to perform an experiment, a chemist needs an element that has similar properties of potassium (K) but has a lower atomic mass. Which element should the chemist select for the experiment?

• Rubidium (Rb)

• Sodium (Na)

• Magnesium (Mg)

• Calcium (Ca)

A student is asked to identify an element that is a

non-reactive gas and does not conduct electricity. Within which group on the Periodic Table would the element most likely be located?

• Group 2

• Group 14

• Group 16

• Group 18

Which of the following statements best describes the patterns and trends of the Periodic Table?

• The atomic number and atomic mass decrease from left to right across a period; energy levels decrease from top to bottom down a group.

• The atomic number and atomic mass increase from left to right across a period; energy levels decrease from top to bottom down a group.

• The atomic number and atomic mass increase from left to right across a period; energy levels increase from top to bottom down a group.

• The atomic number and atomic mass decrease from left to right across a period; energy levels increase from top to bottom down a group.

Which of the following groups in the Periodic Table is made from non-reactive elements?

• Group 1

• Group 4

• Group 17

• Group 18

What conclusion can be made about the elements shown above?

• Phosphorus has more valence electrons than nitrogen.

• Carbon has fewer protons in its nucleus than nitrogen.

• Phosphorus is more like silicon than it is like nitrogen.

• Aluminum is smaller than carbon.

Students were asked to identify the location of elements in the periodic table based on clues printed on game cards shown above.

Based on the data, which periodic table shows the correct location of the four elements?

• 
• 
• 
• 

Which pair of properties describes the elements in Group 18?

• They are chemically stable and liquid at room temperature.

• They have eight valence electrons and are flammable.

• They are magnetic and boil at low temperatures.

• They are gaseous at room temperature and chemically stable.

Element R and Element Q have the same number of valence electrons. These elements both have similar chemical behavior, but Element R has fewer energy levels than Element Q. Which statement best describes the positions of the two elements in the periodic table?

• The two elements are in the same period, with Element R the first element in the period and Element Q the last element.

• The two elements are side by side in the same period, with Element Q to the left of Element R.

• The two elements are in the same group, with Element R just above Element Q.

• The two elements are in the same group, with Element Q at the top of the group and Element R at the bottom.

Students in a science class prepared flash cards so that they could quiz one another about the arrangement of the periodic table. One of the flash cards contained information about two elements, Element L and Element M, picture shown above.

The students had to use the information on the flash card to determine possible positions of the two elements on a blank periodic table.

Which periodic table has the elements placed in locations that match the information on the flash card?

• 
• 
• 
• 

The periodic table is organized into groups and periods of elements. The characteristics of a certain group of elements are listed above.

Which of these elements is in this group?

• Lithium

• Strontium

• Aluminum

• Silicon
