Atomic spectra Study guides, Class notes & Summaries

In Atomic Spectra lab, Vernier angles (V) in degrees of a Hg-lamp has a linear dependence on wavelength (λ) in nm of line spectra: V = 0.146 λ−10.85 a) Predict the Vernier angle in degree for a line that has a wavelength of 510 nm. b) If a student found a line at a Vernier angle of 76.5°, what is the wavelength in nm of this line? - Answer- a) 63.61 b) 598.288 Best-fit line equation commonly takes "y=mx+b" format. What are y, x, m and b? - Answer- y = y-value x= x-value m = slope ...

Highly detailed notes on Unit 1 - Atomic Structure and the Periodic Table Edexcel A-Level Chemistry. Covers all the specification points of unit 1. Contains all the information needed for this topic and allowed me to achieve an A* in chemistry. Covers the definitions needed, mass spectrometry, analysis of mass spectra, ionisation energy, electron configuration, the periodic table, groups, periods and blocks, shielding, nuclear charge, periodicity, valency, atomic radius and electron affinity.

A Level Edexcel Chemistry - Topic 1 - Atomic Structure and Periodic Table Fully updated notes providing drop down answers to self made questions designed from numerous textbooks and exam mark schemes. During my revision, I created these drop down questions and answers by extracting the key information needed to achieve top marks in exams. I achieved a high A* using only these notes. Notes for all other topics have been released on my page :) Hope I can help!

Instrumental Analysis ACS Final Prep Exam Questions With Correct Answers what are the difference between calibration sensitivity and analytical sensitivity - answercalibration sensitivity is the slope of a calibration curve at the concentration of interest while analytical sensitivity is a response to the noise ratio how to calculate calibration sensitivity - answery=mx+b (m is the calibration sensitivity) graph concentration vs mean analytical signal how to find the analytical sensitivit...
