DAT Chemistry Final Exam Prep Questions Correctly Answered. Electromagnetic spectrum - CORRECT ANSWER Raging (longest wave length) Martins Invaded (ROYGBIV) Using X-ray Guns (shortest wave length) Aufbau - CORRECT ANSWER lowest energy fills first Heisenberg uncertainty principle - CORRECT ANSWER Pauli exclusion - CORRECT ANSWER no two electrons can have the same 4 numbers Hunds rule - CORRECT ANSWER dont pair up electrons until you have too n - CORRECT ANSWER princip...

Pauli exclusion principle - ACCURATE ANSWERS no two electrons in an atom may possess identical sets of the four quantum numbers Aufbau principal - ACCURATE ANSWERS states that when the electrons of an atom are all in the ground state, they occupy the orbital's of the lowest energy, thereby minimizing the atoms total electronic energy. Hunds rule - ACCURATE ANSWERS when filling a set of degenerate orbitals, the number of unpaired electrons will be maximized and these electrons will have pa...

What consists of a small, positively charged nucleus surrounded by electrons? an atom What does a nucleus consist of? protons and neutrons Atomic number? the number of protons in the nucleus Mass number? the total number of protons and neutrons in the nucleus Isotopes? atoms of the same element that have the same atomic number (protons) but different mass numbers (neutrons) How to find average atomic mass? natural % abundance x mass (amu),of each isotope,...

This has notes based on what I went over in class highlighting the most important stuff that will show up on the test most likely, and highlighting others that may or may not show up on the test. It is heavily based on what I needed. It has examples, and basically a summary of the entire chapter in very quick slides. This document just had a lot of important notes, important definitions, and lots of examples, and everything is clean and well-made in order to keep everything from being confusi...

This document just had a lot of important notes, important definitions, and lots of examples, and everything is clean and well-made in order to keep everything from being confusing as long as you understand everything up until this point. There are some explanations but this is from the point of view of an average person that just happened to get an A in the class and pass the final for General Chemistry 1 with a %90.

Relative atomic mass average mass of an atom of an element (taking into account all of its isotopes) relative to 1/12 of the mass of a 12C atom Atomic structure exceptions Cu - 1s2 2s2 2p6 3s2 3p6 4s1 3d10 Cr - 1s2 2s2 2p6 3s2 3p6 4s1 3d5 chooses to have all 3d shell filled Hund's Rule electrons prefer to occupy orbitals on their own and only couple up when no empty orbitals of the same energy are available (since electrons paired up will cause repulsion) 4s orbital rule 4s is lo...

This document has in-depth concept clarity of structure of atom from its history to its real meaning. This notes has been made by researching through many sources and many books. I would like to say that this document is best in the internet for class 11th or JEE mains and advanced in structure of atom. The topic covered in this document are: 1. Discovery of Sub- Atomic Particle 2. CRT Experiment 3. Milikan Oil drop experiment 4.Calculation of charge and mass of electron 5. discovery of...

Where are electrons removed from? - Answers--From highest to lowest energy orbitals -Exception: 4s valence electrons are removed before 3d non-valence electrons Paramagnetic - Answers-At least one unpaired electron (attracted by magnet) Diamagnetic - Answers-All electrons are paired (repelled by magnet) Ground State - Answers-Lowest energy electron configuration Electron Configuration Exceptions - Answers--Chromium: [Ar] 4s1 3d5 -Copper: [Ar] 4s1 3d10 Same Group Elements (going ...
