Question

grouping metals by chemical property

which metals have similar chemical properties? choose four correct answers

calcium
rubidium
platinum
beryllium
titanium
barium
radium

Explanation:

Identify the periodic table group

Using the Periodic Table Groups and Alkaline Earth Metals knowledge points

• Elements in the same group (column) of the periodic table share similar chemical properties because they have the same number of valence electrons.
• Looking at the options: calcium (\(\text{Ca}\)), barium (\(\text{Ba}\)), radium (\(\text{Ra}\)), and beryllium (\(\text{Be}\)) all belong to Group 2.
• Group 2 elements are known as the alkaline earth metals.

Evaluate the other options

Using the Periodic Table Groups knowledge point

• Rubidium (\(\text{Rb}\)) is an alkali metal in Group 1.
• Titanium (\(\text{Ti}\)) and platinum (\(\text{Pt}\)) are transition metals.
• Therefore, the four metals with similar chemical properties are calcium, barium, radium, and beryllium.

Answer:

• calcium (Correct answer)
• rubidium
• platinum
• beryllium (Correct answer)
• titanium
• barium (Correct answer)
• radium (Correct answer)
