based on the information in the table, which two elements are most likely in the same group, and why? facts about four elements element atomic mass (amu) total electrons valence electrons year isolated bismuth (bi) 209 83 5 1753 nitrogen (n) 14 7 5 1772 oxygen (o) 16 8 6 1772 sodium (na) 23 11 1 1807 thallium (tl) 204 81 3 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 electrons

Answer

Brief Explanations:

Elements in the same group of the periodic table have the same number of valence electrons. Bismuth and nitrogen both have 5 valence - electrons. Atomic mass, year of isolation, and name suffix are not determining factors for elements being in the same group.

Answer:

bismuth and nitrogen, because they have the same number of valence electrons
