Answer:
A.) Titanium
Step-by-step explanation:
The graph appears to be a mass spectrum. This graph describes the abundance of an element in a sample. The x-axis measures the mass of the element. As such, you can identify the element by determining which element has an atomic weight (g/mol) that matches the highest peak.
Titanium = 47.867 g/mol
Cadmium = 112.41 g/mol
Vanadium = 50.942 g/mol
The highest peak appears to be at 48. From these atomic weights, it seems that titanium is the element with the closest mass.
This graph is measuring an unknown element, so ideally, there would be only one peak. If this is a graph of one element, then why are their multiply smaller peaks? The smaller peaks are most likely isotopes or impurities.
