transition elements การใช้

• These are likely to be the transition elements or rare earth elements.
• She also had a transition element named after her on uneven bars.
• Three of the smaller triangles in each large triangle contain transition elements.
• Iron and other transition elements may give the obsidian a dark brown to black color.
• In the 1950s, most inorganic chemistry textbooks defined transition elements as finishing at mercury ).
• The relations satisfied by the transition elements of an orbifold imply those required for a complex of groups.
• Each turn of the speedway has 1, 060 feet of barrier and another 60 feet of transition element approaching the barrier.
• The distance between bars increased even more as gymnasts developed difficult transition elements that required space, such as the Pak salto.
• Zn form a series of isomorphous compounds which were important in the nineteenth century in establishing the correct atomic weights of the transition elements.
• This rule is however only approximate  it only holds for some of the transition elements, and only then in their neutral ground state.
• The color of the specific salt is due to the electronic structure in the d-orbitals of transition elements or in the conjugated organic dye framework.
• The period shares this trait with periods 1 and 3, none of which contain transition elements or inner transition elements, which often vary from the rule.
• The period shares this trait with periods 1 and 3, none of which contain transition elements or inner transition elements, which often vary from the rule.
• Each triangle has a transition element attached to it belonging to the group of exactly one vertex; and the tetrahedra, if there are any, give cocycle relations for the transition elements.
• Each triangle has a transition element attached to it belonging to the group of exactly one vertex; and the tetrahedra, if there are any, give cocycle relations for the transition elements.
• He has pioneered a molecular approach to heterogeneous catalysis, based on transition elements taken as probes, specific isotopes and physical techniques, which provided him with an original position in the field.
• In order to investigate the range and stability of the oxidation states of actinide and other transition elements in fused salt solutions, he pioneered the field of absorption spectroscopy in high-temperature liquids.
• For example, the atomic radius of the metal zirconium, Zr, ( a period-5 transition element ) is 159 pm and that of hafnium, Hf, ( the corresponding period-6 element ) is 156 pm.
• This is particularly true of the transition elements, where quoted electronegativity values are usually, of necessity, averages over several different oxidation states and where trends in electronegativity are harder to see as a result.
• Thus the main difference in oxidation states, between transition elements and other elements is that oxidation states are known in which there is a single atom of the element and one or more unpaired electrons.
