Benchmark 3 Review Part 2

HS.P1U1.1 A student using the periodic table realizes that water is not listed on it. What can the student infer from this observation?

• Water is a combination of elements listed in the periodic table.
• Water is made up of elements yet to be discovered.
• Water is a liquid and liquids are not listed in the periodic table.
• Water is a combination of substances that are not elements.

HS.P1U1.1 The image shows a portion of the periodic table. Which highlighted element in the periodic table is a metal?

• Calcium
• Fluorine
• Hydrogen
• Iodine

HS.P1U1.1 Beryllium (Be), Magnesium (Mg), Calcium (Ca), Strontium (Sr), Barium (Ba), and Radium (Ra) are in the same column in the periodic table. Why are these elements in the same column in the periodic table?

• They have similar properties.
• They have atoms of the same size.
• They have very different properties.
• They have the same number of protons

HS.P1U1.1 Which of the following statements are true about the periodic table? I. The vertical column on the periodic table are called periods. II. The elements in the first group react with oxygen in similar ways. III. The horizontal rows on the periodic table are called groups or families because of their similar chemical behavior. IV. Mendeleev arranged the periodic table so that elements with the most similar properties were in the same group on the periodic table.

• I and II
• II and IV
• II and III
• III and IV

HS.P1U1.1 How many valence electrons does Thallium have?

• 1
• 3
• 6
• 8

HS.P1U1.1 Elements within the same group in the periodic table have similar properties because they have the same number of

• neutrons.
• ions.
• valence electrons.

HS.P1U1.1 Which is not a family of the periodic table?

• alkaline-earth metals
• anions
• halogens
• noble gases

HS.P1U1.1 What information in the periodic table indicates the number of protons in an atom?
