The meaning of TRANSITION METAL is any of various metallic elements (such as chromium, iron, and nickel) that have valence electrons in two shells instead of only one —called also transition element.

摘要: While most chemists agree on what is a metal and what is a non-metal there is a disagreement with respect to what is a metalloid and what is a transition metal. It is believed that this problem can...关键词: Typical metals Less typical metals Transition metals Inner transition ...
Second, the transition metals form many useful alloys, with one another and with other metallic elements. Third, most of these elements dissolve in mineral acids, although a few, such as platinum, silver, and gold, are called “noble”—that is, are unaffected by simple (nonoxidizing) acids...
Transition metals and inner transition metals appear to be similar in the way they are categorized on the periodic table, but they have significant differences in their atomic structure and chemical properties. The two groups of inner transition elements, actinides and lanthanides, behave differently ...
