How are metals different from nonmetals? In what ways are polyatomic ions like simple ions? What is an atom that has more protons than electrons? List three atoms or ions that have the same number of electrons as each of the following. a. S2- b. Al3+ c. P3- d. Kr e. Cs+ How...
How can one know the possible ways to distinguish solutions made up of different ions? Why is (CH_3)_2CHCH_2Cl not an ion? How can you separate compounds? Explain the way in which atoms are held together in a chemical compound. ...
Atoms are the basis of all the elements in the universe, the building blocks of all visible matter, and the secret to nuclear power.
For atoms that gain an electron, they take on a net negative charge and become anions. These are just names for the positive and negatively charged ions, to help distinguish them from neutral atoms and from each other. The important thing to understand about ions is that they are the only ...
At the atomic level different rules of physics apply to those that we observe around us. These quantum rules determine how atoms interact with each other, and this new understanding will enable us to use quantum rules for incredibly advanced and rapid calculations that are far beyond the abi...
Thermodynamics of the Al matrix, stoichiometric compounds, and aqueous solution are specified by the TCAL5, SSUB5, and TCAQ3 databases in the Thermo-Calc software, respectively. We addressed the oxygen’s role in oxidation and corrosion via O-containing ions, excluding dissolved gases, i.e. O2...
It was thought that sodium ions and lithium ions couldn’t be used together in a solid-state electrolyte system because they are similarly charged but have different sizes. It was assumed that the structural framework of a solid-state electrolyte material couldn’t support the movement of two di...
Comparing to a generic two-state model, our models can distinguish class I from class II MHCs and correlate their structural parameters with the TCR/pMHC’s potency to trigger T cell activation. The models are tested by mutagenesis using an MHC and a TCR mutated to alter conformation changes....
But while faster-than-light travel isn't guaranteed impossible, we'd need to harness some pretty exotic physics to make it work. Luckily for sci-fi enthusiasts and theoretical physicists alike, there are lots of avenues to explore. All we have to do is figure out how to not move ourselves...
