Question
Based on the information in the table, which two elements are most likely in the same group, and why?
A table with 5 columns and 5 rows labeled facts about 4 elements. The first column labeled element has entries bismuth (B i), nitrogen (N), oxygen (O), sodium (N a), thallium (T l). The second column labeled atomic mass (a m u) has entries 209, 14, 16, 23, 204. The third column labeled total electrons has entries 83, 7, 8, 11, 81. The fourth column labeled valence electrons has entries 5, 5, 6, 1, 3. The fifth column labeled year isolated has entries 1753, 1772, 1772, 1807, 1861.
bismuth and thallium, because their atomic masses are very similar
nitrogen and oxygen, because they were both first isolated in the same year
sodium and thallium, because their names both end in the same suffix: -ium
bismuth and nitrogen, because they have the same number of valence electron

The two elements that are most likely in the same group are **bismuth (Bi) and thallium (Tl)**, because they both have a similar number of valence electrons (5 for bismuth and 3 for thallium) and they are in the same column of the periodic table (Group 13). This is a key factor in grouping elements, as elements within the same group typically exhibit similar chemical properties and behaviors.
The reasoning of "because their atomic masses are very similar" is less relevant than their grouping based on electronic configuration and chemical properties. Hence, the best match from the provided options is:
**bismuth and thallium, because their atomic masses are very similar (although it's more accurate to say they are in the same group and share properties).**
