Periodic Trends and Atomic Properties

This section explores fundamental periodic trends and atomic properties, essential for understanding chemical behavior.

Definition: Atomic radius trend shows how the size of atoms changes across the periodic table.

Highlight: Electronegativity trend increases from left to right across a period and decreases down a group.

Example: Carbon atomicnumber6atomic number 6 has 6 electrons arranged in 1s² 2s² 2p².

Vocabulary: Effective Nuclear Charge ENCENC refers to the net positive charge experienced by an electron from the nucleus.

Empirical and Molecular Formulas

This section covers how to determine chemical formulas from experimental data.

Definition: An empirical formula represents the simplest whole-number ratio of atoms in a compound.

Example: For a compound with 32.37% Na, 22.57% S, and 45.06% O, the process involves converting percentages to moles.

Highlight: The molecular formula can be determined by comparing the empirical formula mass to the actual molar mass.

Atomic Structure and Significant Figures

This introductory section establishes fundamental chemistry concepts, focusing on atomic structure and numerical precision in calculations.

Definition: Significant figures are digits that carry meaning in a measurement, determining precision in calculations.

Example: In the number 0.0025, there are 2 significant figures as leading zeros don't count.

Highlight: The electron configuration follows a specific order: 1s, 2s, 2p, 3s, 3p, 4s, 3d, and so on, following the Aufbau principle.

Vocabulary: SPDF notation refers to the quantum mechanical description of electron orbitals, where:

  • s = sharp
  • p = principal
  • d = diffuse
  • f = fundamental

The app is very easy to use and well designed. I have found everything I was looking for so far and have been able to learn a lot from the presentations! I will definitely use the app for a class assignment! And of course it also helps a lot as an inspiration.

This app is really great. There are so many study notes and help [...]. My problem subject is French, for example, and the app has so many options for help. Thanks to this app, I have improved my French. I would recommend it to anyone.

Samantha Klich

Android user

Wow, I am really amazed. I just tried the app because I've seen it advertised many times and was absolutely stunned. This app is THE HELP you want for school and above all, it offers so many things, such as workouts and fact sheets, which have been VERY helpful to me personally.

Anna

I think it’s very much worth it and you’ll end up using it a lot once you get the hang of it and even after looking at others notes you can still ask your Artificial intelligence buddy the question and ask to simplify it if you still don’t get it!!! In the end I think it’s worth it 😊👍 ⚠️Also DID I MENTION ITS FREEE YOU DON’T HAVE TO PAY FOR ANYTHING AND STILL GET YOUR GRADES IN PERFECTLY❗️❗️⚠️

Knowunity is the BEST app I’ve used in a minute. This is not an ai review or anything this is genuinely coming from a 7th grade student (I know 2011 im young) but dude this app is a 10/10 i have maintained a 3.8 gpa and have plenty of time for gaming. I love it and my mom is just happy I got good grades

Brad T

Android user

Not only did it help me find the answer but it also showed me alternative ways to solve it. I was horrible in math and science but now I have an a in both subjects. Thanks for the help🤍🤍

David K

iOS user

The app's just great! All I have to do is enter the topic in the search bar and I get the response real fast. I don't have to watch 10 YouTube videos to understand something, so I'm saving my time. Highly recommended!

In school I was really bad at maths but thanks to the app, I am doing better now. I am so grateful that you made the app.

I found this app a couple years ago and it has only gotten better since then. I really love it because it can help with written questions and photo questions. Also, it can find study guides that other people have made as well as flashcard sets and practice tests. The free version is also amazing for students who might not be able to afford it. Would 100% recommend

Aubrey

Best app if you're in Highschool or Junior high. I have been using this app for 2 school years and it's the best, it's good if you don't have anyone to help you with school work.😋🩷🎀

This app is phenomenal down to the correct info and the various topics you can study! I greatly recommend it for people who struggle with procrastination and those who need homework help. It has been perfectly accurate for world 1 history as far as I’ve seen! Geometry too!
