Which elements have similar behavior: barium, silicon, aluminum, strontium, osmium, and beryllium?
Question
Which elements have similar behavior:
- barium
- silicon
- aluminum
- strontium
- osmium
- beryllium?
Solution
Elements that have similar behavior are typically found in the same group (column) of the periodic table because they have the same number of valence electrons, which determines their chemical properties.
Step 1: Define the Problem
Identify which elements among barium, silicon, aluminum, strontium, osmium, and beryllium have similar chemical behaviors.
Step 2: Break Down the Problem
- Barium (Ba) and Strontium (Sr) are both in Group 2 (alkaline earth metals).
- Silicon (Si) is in Group 14.
- Aluminum (Al) is in Group 13.
- Osmium (Os) is in Group 8.
- Beryllium (Be) is also in Group 2 (alkaline earth metals).
Step 3: Apply Relevant Concepts
Elements in the same group have similar chemical properties. Therefore, we need to identify which elements are in the same group.
Step 4: Analysis, Verify and Summarize
- Barium (Ba), Strontium (Sr), and Beryllium (Be) are all in Group 2, so they have similar chemical behaviors as alkaline earth metals.
- Silicon (Si), Aluminum (Al), and Osmium (Os) are in different groups and thus have different chemical behaviors.
Final Answer
Barium, strontium, and beryllium have similar chemical behaviors as they are all alkaline earth metals in Group 2 of the periodic table.
