You're welcome! Reviewing chemistry is a great idea, and don't worry, you've got this! Chemistry can be a challenging subject, but with dedication and practice, you can improve your understanding and confidence. 😊📚🔬
Hello I’m a bit confused on the orbital question.. the answer says each can hold a maximum of 2 but wouldn’t it vary on which orbital since it goes 2, 6, 10, then 14? My teas is in 2 weeks so I just wanted some clarification just in case ! 🙃
It seems like there might be a misunderstanding here regarding orbitals and electron configuration. In atomic physics and quantum chemistry, the electron configuration describes the distribution of an atom's electrons among its atomic orbitals. When we talk about an orbital in the context of electron configuration, we usually refer to a specific area around the nucleus of an atom where an electron is likely to be found. There are four types of orbitals (s, p, d, f), and each has a different shape and energy level: s orbital: spherical shape, can hold a maximum of 2 electrons. p orbital: dumbbell shape, each p orbital can hold a maximum of 2 electrons, but there are three p orbitals (px, py, pz), so together they can hold a maximum of 6 electrons. d orbital: complex shape, each d orbital can hold a maximum of 2 electrons, but there are five d orbitals, so together they can hold a maximum of 10 electrons. f orbital: even more complex shape, each f orbital can hold a maximum of 2 electrons, but there are seven f orbitals, so together they can hold a maximum of 14 electrons. So when the answer says each orbital can hold a maximum of 2 electrons, it is referring to an individual orbital, not the entire subshell (s, p, d, or f). I hope this clarifies your doubt! Best of luck with your TEAS exam in two weeks! You're doing great by reviewing and asking questions to make sure you understand the material. Keep it up! 😊👍
I'm doing the course right now and I feel well-rounded about each and every topic. There are tons of practice questions and short lecture videos for each topic. Good luck!
I studied your chemistry review today after 14 years of not being in a chemistry class. All hope was lost when I found out chemistry was on this exam. Well I'm sure your review paid off because I scored 12 out of 15 on this and I cannot thank you enough! I had no idea that color was a physical property. In regards to question 10, I do not understand how cooking an egg wasn't the answer being that it goes from a liquid to a solid but is still an egg. Is it because the liquid egg cannot be recovered from the solid?
Congratulations on scoring 12 out of 15 in the chemistry section, especially after such a long break from the subject! That's a significant achievement, and I'm glad to hear the review was helpful for you. Regarding your question about cooking an egg, you're on the right track. When an egg is cooked, the process indeed changes it from a liquid to a solid. This change is considered a chemical change, not just a physical one, because it involves the alteration of the egg's proteins through a process called denaturation. This means the proteins unfold and then bond together in a different way, which changes the egg's structure at the molecular level. The key factor that makes cooking an egg a chemical change rather than a physical one is that this process is irreversible under normal conditions. You can't turn a cooked egg back into its raw, liquid state, which is a hallmark of chemical changes. They create new substances with different properties, and the original substance can't be easily recovered. Keep up the great work with your studies, and don't hesitate to reach out if you have more questions. Your dedication and curiosity are sure to serve you well in your academic journey! 🌟🔬📚

Thank you. Looks like i need to review chemistry😬

Dose this site really help with the teas test?
1000%

@@isabelladeluna8626 okay. I just bought it so I will give it a go
@@andreisison4689 did you take your test already?
