Which best describes the relationship of the elements?
Magnesium has a larger atomic number.
Phosphorus has a larger atomic mass.
Magnesium is in the same category as phosphorus.
Phosphorus has similar chemical properties as magnesium.
Elements in group 2 are all called alkaline earth metals. What is most similar about the alkaline earth metals?
how many protons and neutrons they have
which chemical properties they have
how many total electrons they have
which period they are most often found in
Based on the information in the table, which two elements are most likely in the same group, and why?
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
Based on the information in the table, which elements are most likely in the same periods of the periodic table?
Boron and carbon are likely together in one period because they have very close atomic masses.
Aluminum, boron, and carbon are likely together in one period because they were first isolated in the first half of the 1800s.
Boron and carbon are likely together in one period because they each end in “-on."
Aluminum, boron, and gallium are likely together in one group because they have the same number of valence electrons.
