Thetransition metalsinclude 34 metals in the middle of the periodic table. These metals are named this way, as they can take on many different charges, due to their valence electrons being in the d-orbitals. As a result, these metals tend to have a wide variety of colors and properties....
Inner Transition Metals In the periodic table, two series of elements, atomic numbers 58-71 and 90-103, are placed below the main body of the table. These elements are separated from the main table because putting them in their proper position would make the table very wide. The elements i...

Calderglen High School 9. What is ATOMIC NUMBER? answer The number of protons in an atom. It is the number by which elements are arranged in the Periodic Table Calderglen High School Why are atoms electrically neutral? 10. answer The number of positively charged protons equals the number of...
This is because an element's atomic number tells us the number of protons in its nucleus and that number never changes, which takes care of the problem brought on by isotopes, which have different numbers of neutrons. Read Henry Moseley | Periodic Table, Atomic Theory & Discovery Lesson ...
Meyer worked in several areas of chemistry, but much of his activity grew out of his preoccupation with the classification of the elements. He worked on recalculating a number of atomic weights and made use of theperiodic tablefor predicting and studying related elements’ chemical properties. ...
