Hello!
the atomic difference between uranium-235 and uranium-238 is that <span>uranium-235 has three fewer neutrons than uranium-238
Isotopes are atoms of the same elements which are only different in their amount of neutrons. That difference in the number of neutrons gives them different masses. Some isotopes are unstable, and they release neutrons (radiation) to transform into other, more stable, isotopes. When this happens the isotope is called a "radioactive isotope".
Have a nice day!</span>
Answer:
1) The correct step in the scientific method that Victor did is Construct a hypothesis.
2) Given mass and density, volume is calculated as mass divided by density.
Explanation:
1) Before doing the assay and make a graph with the results obtained, Victor should think what he wants to prove, so he should make a hypoythesis to test with the assay.
2) The formula of density is
density = mass/volume ⇒ density x volume = mass ⇒ volume = mass/density.
Answer: SO2(Sulfur Dioxide) Molecular Geometry & Lewis Structure
Explanation: So2Molecular Geometry
We know that the shape which minimizes the repulsions of electronics pairs is adopted by the molecule to form the structure. The molecular shape of SO2 is same as the molecular geometry of Carbon Dioxide (CO2). We will show the bonding of SO2 without making assumption below.
