Neodymium is not found naturally in metallic form or unmixed with other lanthanides, and it is usually refined for general use. 0. Lutetium is the last element in the lanthanide series, and it is traditionally counted among the rare earths. Question: Arrange The Elements According To Their Tirst Ionizanon Energies. Therefore the electronegativity is greatest at the top-right of the periodic table and decreases toward the bottom-left. It is obtained chiefly from the mineral cassiterite, which contains tin dioxide. 8 years ago. asked by @nicolep148 • about 1 year ago • Chemistry → Periodic Trend: Ionization Energy You can look at where they are in the periodic table and know that IE … The metal is found in the Earth’s crust in the pure, free elemental form (“native silver”), as an alloy with gold and other metals, and in minerals such as argentite and chlorargyrite.
