Page 1: Calculating Relative Atomic Mass and Electron Configuration

This page covers the essential concepts of calculating relative atomic mass (RAM) and understanding electron configurations. The detailed explanation includes the RAM of titanium calculation using isotopic compositions and demonstrates the mass spectrometry isotopic composition process.

Definition: Relative atomic mass (RAM) is calculated by multiplying each isotope's mass by its percentage composition and summing the results.

Example: The RAM calculation for titanium using its isotopes:

Ti-46 (8.9%)
Ti-47 (9.8%)
Ti-48 (81.3%) Calculation: (46 × 8.9) + (47 × 9.8) + (48 × 81.3) = 47.7

Highlight: When dealing with electron configurations, the 4s orbital fills before the 3d orbital, despite 3d being lower in number.

Vocabulary: Mass spectrometry - A scientific process used to determine the atomic mass of molecules by analyzing their mass-to-charge ratio.

Example: For chlorine's RAM of 35.5: Let x be the percentage of Cl-35 Let y be the percentage of Cl-37 x + y = 100 35.5 = $35x + 37y$ /100 Solving gives x = 75% and y = 25%

This app has made me feel so much more confident in my exam prep, not only through boosting my own self confidence through the features that allow you to connect with others and feel less alone, but also through the way the app itself is centred around making you feel better. It is easy to navigate, fun to use, and helpful to anyone struggling in absolutely any way.

I know a lot of apps use fake accounts to boost their reviews but this app deserves it all. Originally I was getting 4 in my English exams and this time I got a grade 7. I didn’t even know about this app three days until the exam and it has helped A LOT. Please actually trust me and use it as I’m sure you too will see developments.
