An element X exists in nature as two isotopes: X-10 (20% abundance) and X-11 (80% abundance). A student calculates its relative atomic mass to understand why the periodic table does not show whole numbers for most elements. What will be the correct relative atomic mass of element X-10?

A naturally occurring element has isotopes with masses 35 and 37. If the average atomic mass is closer to 35 than 37, what does this indicate about its isotopic composition?

An element has two isotopes: A-24 and A-26. The relative atomic mass is found to be 24.5. Which statement correctly explains this value?

A chemist calculates the relative atomic mass of an element using isotopic data. Why is this value usually not a whole number?

Element Y has isotopes Y-12 (75%) and Y-13 (25%). A student mistakenly calculates the atomic mass by simple averaging: (12+13) / 2=12.5. Why is this incorrect?

A sample contains two isotopes of chlorine: Cl-35 (75%)and Cl-37 (25%). What is the correct relative atomic mass?

Which statement best describes the concept of relative atomic mass in terms of real-world samples?

An element has isotopes with masses 50 and 52. If the relative atomic mass is 50.2, what can be inferred?

A student argues that isotopic abundance does not affect periodic table values. Which correction is scientifically accurate?

If an element has a dominant isotope of mass 100 with 99% abundance, and another isotope of mass 102 with 1% abundance, what will the relative atomic mass be closest to?

Why do chemists use relative atomic mass instead of mass number for calculations involving elements in reactions?

An element shows three isotopes with varying abundances. Which mathematical method is used to determine its relative atomic mass?
