A sample of an element produces a mass spectrum with two peaks at $m/z$ values of 35 and 37, with relative abundances of 75% and 25% respectively. Which statement correctly identifies this element and describes a key feature of its mass spectrum?
Determine which element the mass spectrum belongs to.
Neon exists as two stable isotopes: $\ce{^{20}Ne}$ and $\ce{^{22}Ne}$. The mass spectrum of neon shows two peaks at mass-to-charge ratios of 20 and 22. Explain why the peak at mass-to-charge ratio 20 is significantly taller than the peak at mass-to-charge ratio 22.
