C. Chemical properties
D. Partial uses
A

C. Chemical properties

18
Q

Why is Mercury the only metal to have been used in thermometers

A

Because it is a liquid at room temperature

19
Q

Alkali metals, alkaline earth metals, or transition elements. The metals cannot react with water or oxygen and must be shiny and strong

A

Transition metals (hold would be a good choice)

20
Q

Infer whether you are looking at a graph of elements within a group or across a period. Explain.

A

This graph would go with a period of elements

21
Q

Contrast aluminum and nitrogen. Show why aluminum is a metal and nitrogen is not

A

Aluminum is shiny, malleable, luster, solid at room temperature, nitrogen is a gas at room temperature

22
Q

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

A

Gold for group A and carbon for group B

23
Q

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

A

Group A are metals, group B are nonmetals. Silicon would belong to neither because it’s a matalloid

24
Q

Which group in the figure above yields the strongest building elements? Why?

A

Group A, there metals, transition elements, and increased strength

25
Q

How is today’s periodic table of elements organized

A

Increasing in atomic number (Mosley made it that way) (Mendeleev made it increasing in atomic mass)

26
Q

What connection does the human body have with the elements in the periodic table

A

Many are found in the human body (iron, carbon, oxygen, potassium, calcium)

27
Q 
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
A

C. Increasing atomic number
