-Discussion Questions: A. Explain what the lines in element emission spectra represent? B. What is the simplest reason why the atomic emission spectrum of helium has more lines than hydrogen? C. Label to the right where each series would fall in the electromagnetic spectrum (meaning visible, IR, UV, gamma, microwave, radio, etc. Figures 1,5 and 6 may be helpful.) Lyman Series Balmer Series Paschen Series

Answer 1

(c) A) Emission sputrum show many lines. Each emission line represent a different sump en energy that an electron in an atom could make it is not equal to number of election in an atom, when an atom gain energy, the elections in it get excited and make transition to different energy levels. These transitions are shown by spectral lines By since, helsum has more electrons than bydrogen. it has more spectral lines than hydrogen, infact, hydrogen enmitted three emission lines & red, bhee & nokt i pelum has of ennasion lines two red, two green one yellow, indigo and violet each. and
