Which element is most likely to react with potassium A. Bromine B. Calcium C. Nickel D. Sodium
A. Bromine
Which group of elements can act as semiconductors A. Halogens B. Metalloids C. Metals D. Noble gases
B. Metalloids
How do density and atomic mass change as atomic number number increases
A. Density & atomic mass decrease
B. Density & atomic mass increases
C. Density decreases & atomic mass increases
D. Density increases & atomic mass decreases
B. Density and atomic mass increases
Which elements have high densities, strength, and resistance to corrosion A. Alkali metals B. Alkaline earth metals C. Metalloids D. Transition elements
D. Transition elements
Which is a property of a metal A. It is brittle B. It is a good insulator C. It has a dull appearance D. It is malleable
D. It is malleable
What is the name of group 17 A. Halogens B. Metalloids C. Metals D. Noble gases
A. Halogens
Which is a property of these elements A. They are conductors B. They are semiconductors C. They are nonreactive with other D. They react easily with other elements
D. They react easily with other elements
What is one similarity among elements in a group A. Atomic mass B. Atomic weight C. Chemical properties D. Partial uses
C. Chemical properties
Why is Mercury the only metal to have been used in thermometers
Because it is a liquid at room temperature
Alkali metals, alkaline earth metals, or transition elements. The metals cannot react with water or oxygen and must be shiny and strong
Transition metals (hold would be a good choice)
Infer whether you are looking at a graph of elements within a group or across a period. Explain.
This graph would go with a period of elements
Contrast aluminum and nitrogen. Show why aluminum is a metal and nitrogen is not
Aluminum is shiny, malleable, luster, solid at room temperature, nitrogen is a gas at room temperature
Group A has iron, silver, and sodium. Group B has neon, oxygen, and nitrogen name one other element that fits in group A and one for group B
Gold for group A and carbon for group B
Group A and B contain 2 elements. Identify each group as metals, nonmetals, or Metalloids. Would silicon belong to one of these groups? Why or why not
Group A are metals, group B are nonmetals. Silicon would belong to neither because it’s a matalloid
Which group in the figure above yields the strongest building elements? Why?
Group A, there metals, transition elements, and increased strength
How is today’s periodic table of elements organized
Increasing in atomic number (Mosley made it that way) (Mendeleev made it increasing in atomic mass)
What connection does the human body have with the elements in the periodic table
Many are found in the human body (iron, carbon, oxygen, potassium, calcium)
What determines the order of the elements on today's periodic table A. Increasing atomic mass B. Decreasing atomic mass C. Increasing atomic number D. Decreasing atomic number
C. Increasing atomic number
