Pseudo-Noble Gas Configurations: A Unique Path to Atomic Stability
Want To Learn More? To watch the entire video and ALL of the videos in the series:
Discover the concept of the pseudo-noble gas configuration, differentiating it from the traditional noble gas configuration. Examine examples like tin and indium to illustrate how elements achieve this unique state of stability. Unpack the intriguing intricacies within atomic structures.
Molecular Lewis Structures for CH?, CO?, H?Se, and NH?
Want To Learn More? To watch the entire video and ALL of the videos in the series:
In this video, we demonstrate the creation of Lewis structures for methane, carbon dioxide, hydrogen selenide, and ammonia, highlighting the arrangement of atoms and bonds in each molecule. The video emphasizes the importance of Lewis structures in visualizing atomic bonding and the presence of lone electron pairs.
Lattice Energy: Always Positive; Hydration Energy: Always Negative
Want To Learn More? To watch the entire video and ALL of the videos in the series:
In this video we clarify why lattice energy in solids is always a positive value due to the energy needed to separate ions making it an endothermic process. On the flip side hydration energy is always negative as it releases heat when ions dissolve in water making it an exothermic reaction. We use sodium chloride as a real-world example to illustrate these crucial thermodynamic concepts
Mastering Unit Conversions: From Light-Years to Feet/sec
Want To Learn More? To watch the entire video and ALL of the videos in the series:
Learn how to convert between various units of measurement, ranging from cosmic distances to everyday lengths. The video takes viewers through the process of translating light-years into miles, yards into centimeters, and incredibly high speeds from cm/s to feet per second. Simplifying complex conversions, this guide offers clarity in the world of physics.
Electrons in outer shell of: Potassium, Calcium, Aluminum
Want To Learn More? To watch the entire video and ALL of the videos in the series:
This video explains the importance of the number of valence electrons in an element's chemical behavior and demonstrates how to determine the valence electrons for potassium, calcium, and aluminum based on their positions in the periodic table. Valence electrons dictate an element's reactivity with other elements, making this knowledge essential for understanding chemical reactions.
Calculating Density: Rectangular Metal Bar & Significance
Want To Learn More? To watch the entire video and ALL of the videos in the series:
Learn the process of determining the density of a rectangular metal bar using its measurements. Understand how volume and mass play a crucial role in the calculation, and the importance of representing results with the correct number of significant figures
