Periodic Table Exam Review

Which group on the Periodic Table has at least one element in each of the three phases of matter at STP?

• 1
• 2
• 17
• 18

In which period of the Periodic Table are transition elements found?

• 1
• 2
• 3
• 4

Which symbol represents a particle with a total of 10 electrons?

• 
• 
• 
• 

Which of the following elements has the greatest density at STP?

• sodium
• silicon
• selenium
• scandium

Based on the Periodic Table of Elements, which Group 2 element is the most active?

• Ba
• Sr
• Mg
• Ca

The amount of energy required to remove the outermost electron from a gaseous atom in the ground state is known as:

• first ionization energy
• entropy
• electronegativity
• temperature

Atoms of metallic elements tend to:

• lose electrons and form positive ions
• gain electrons and form negative ions
• gain electrons and form positive ions
• lose electrons and form negative ions

The table shows some properties of elements A, B, C, and D. Which element is most likely a nonmetal?

• A
• B
• C
• D

As the Group 1 elements of the Periodic Table are considered from top to bottom, the first ionization energy of each successive element decreases. One reason for this is that the:

• nuclear charge is increasing
• distance between the valence electrons and the nucleus is increasing
• number of neutrons is increasing
• number of principal energy levels is decreasing

Compared to the valence electrons of a nonmetallic atom, the valence electrons of a metallic atom are generally:

• fewer in number and less strongly held
• fewer in number and more strongly held
• greater in number and less strongly held
• greater in number and more strongly held
