Click For Summary
Every chemical element is uniquely defined by its atomic number, which corresponds to the number of protons in its nucleus. While elements can have different isotopes, these variations involve differing neutron counts while maintaining the same proton number. For instance, Deuterium and Tritium are isotopes of Hydrogen, showcasing this concept. Isotopes retain the chemical properties of their parent element but can differ in stability and mass. Understanding atomic structure is essential for grasping the fundamentals of chemistry.

This is very interesting to me. Does every element differentiates solely by it's atomic number?

Yes each element has its own unique proton number. Elements can have different isotopes which have a differing number of neutrons, but the same number as protons as the element. Deuterium and Tritium are two isotopes of Hydrogen for example.
 

Thread 'Does acceleration affect impact energy vs constant velocity?'

I do not have a good working knowledge of physics yet. I tried to piece this together but after researching this, I couldn’t figure out the correct laws of physics to combine to develop a formula to answer this question. Ex. 1 - A moving object impacts a static object at a constant velocity. Ex. 2 - A moving object impacts a static object at the same velocity but is accelerating at the moment of impact. Assuming the mass of the objects is the same and the velocity at the moment of impact...
