Atomic Number = 6, Protons = 6, Electrons = 6, Atomic Weight = 12.0, Electrons in first energy level = 2, second energy level = 4. What is the 10th element on the periodic table? What element from the first 10 elements would be most similar in properties to the element of atomic n...
A chemical element is a pure chemical substance consisting of one type of atom distinguished by its atomic number, which is the number of protons in its nucleus. The term is also used to refer to a pure chemical substance composed of atoms with the same number of protons.[1] Common exampl...
Distribution coefficient results, expressed as a competition between solution and solid-state complexation terms, indicate that rare earth element complexation, both in solution and on surfaces, strongly increases with atomic number. Relatively small differences in rare earth element distribution coefficients...

Sample Group: Atomic Emission Lamps Aluminum-scandium master alloy. This irregular lump comes from Tim Worstall, the world's leading expert on the scandium trade by virtue of the fact that he is a good fraction of the world's scandium traders. Virtually no pure scandium metal is sold in th...
In general, an atom’s electronegativity is affected by both its atomic number and the distance at which its valence electrons reside from the charged nucleus. The higher the associated electronegativity number, the more an element or compound attracts electrons towards it. ...
Gilbert Atomic Energy Spinthariscope. This cheaply-made (but probably quite functional) cardboard tube spinthariscope was part of a Gilbert chemistry set in the 1950's or 60's. I don't have the rest of the set, just the spinthariscope, and I'm just guessing that it contained uranium ...
As paste materials, Rh resinate (#8826), Si resinate (#28FC) and Pb resinate (#207-A) produced by N.E. CHEMCAT CORP. were mixed in an atomic proportion of 1:1:0.5. A terpineol extract of asphalt was added to the system in an amount of 40% by weight based on the total weight...
