Firstly, the planetary model of the atom failed to explain why individual atoms produce discrete line spectra. ... This would imply that atoms are naturally unstable. Since atoms are generally stable, this means that the model does not correctly describe the structure of the atom. What is the...
Which group of the periodic table contains atoms with a stable outer electron configuration? What is the relationship between electronegativity and the ionic character of a chemical bond? Which one of the elements below has the lowest ionization energy? Ex...
Which element is an alkali metal? a. Li b. Be c. B Alkali Metals: The alkali metals have some common characteristics: They are overall very reactive and react vigorously with water. They all have 1 valence electron. They are soft metals that can be cut with a knife by hand. ...
The only chemical elements that are stable single atom molecules at standard temperature and pressure (STP) are the noble gases. These are helium, neon, argon, krypton, xenon, and radon. What element is not diatomic in nature? Carbon does not exist as a diatomic molecule. The seven elements...
Physicists have equations that predict how molecules zig and zag, how atoms split, and how the heart of the atom holds together. They can continue zooming into the sub-sub-subatomic world for quite a while, but eventually — for any event playing out on a stage roughly 10⁻³⁵ ...
Conductivity is the ability of a substance to carry an electric charge. Electrons then must be able to flow freely through the material in order for it to conduct. There are three classes of materials with regards to conductivity: conductors, semiconductors, and noncond...
The nickel atom is a type of vertex for the closo-NiC2B9 cluster while the nido-NC2B8 group where it is found as well as carbon atoms in the open NiC2B2 pentagonal face. It is assumed that its development proceeds through the nucleophile-induced removal of the B(6)H vertex accompanied...
Thought: maybe thats why they hate fire...hmmm Definitely could be used as an endo-skeleton though! Perhaps a Titanium Carbide would be strong, durable, stable and light enough to support a Xenomorph exoskeleton? This is interesting! Blackwinter...
