Is the Ti2+ ion diamagnetic? Explain. Is the Zn2+ ion diamagnetic? Explain. Is the Mn2+ ion diamagnetic? Explain. The atomic number in an element is 73. Is this element diamagnetic or paramagnetic? What causes an atom, molecule, or ion to be paramagnetic? Which of the ions (Pb2+, ...
Thus while Mendeleev was able to predict the existence and the chemistry of the missing elements eka-boron, eka-aluminium, and eka-silicon (scandium, gallium, and germanium) with considerable certainty, he was much more tentative when it came to other elements. In his Faraday Lecture of 1889 ...
One of the applications I find most interesting is its use as a turbine fluid and rocket propellant. The low ionization energy, high density and molecular mass, and the fact it is stable as a liquid at room temperature made the element a good candidate for ion engines. If it were not fo...
When an ionic salt is added to the water then it dissociates in its constituents ions and these ion gets hydrated by the water molecules. The process of surrounding water molecules towards these ions is known as hydration.The hydration plays an important role in the solubility of ...
What ion is scandium most likely to form? Is this a cation or an anion?What ion is barium most likely to form? Is this a cation or an anion?How many total electrons are there in the ion, CO_3^2-?How many total electrons are present in a P3- ion?
Why is CH_4 more stable than (CH_3)^+? Why NH4+ ion is not strong ligand? Define the term chelate. Why is an enolate ion generally more reactive than a neutral enol? The hexaaquascandium(III) ion, (Sc(H_2O)_6)^3+, is colorless. Explain why this might be expected. ...
If you look at the periodic table the light elements usually have close to a 1:1 ratio of protons to neutrons. Starting with Scandium (atomic number 21) they begin to deviate significantly. Considerin The sum of an atom's protons and ...
