Answer to Question #254502 in General Chemistry for shamsa

Question

2. You performed an X-ray spectroscopy experiment and observed the emission from unknown element A to be 21×1016 Hz and the emission from unknown element B to be 71.5×1016 Hz. It is known that X-ray frequency increases with atomic number and fits the quadratic function of Y=X2. If Unknown A is Neon, what is the likely identity of element B?

Answer 1

Unknown B is likely Argon

Explanation:-

$\frac{Element B}{Element A}$ =$\frac{71.5}{21}=3.4$

But the quadratic function Y=X²

Y=3.4×2=6.8

Frequency =6.8 Hence the frequency of Argon
