Abegg discovered the theory of freezing-point depression and anticipated Gilbert Newton Lewis's octet rule by revealing that the lowest and highest oxidation states of elements often differ by eight. He researched many topics in physical chemistry, including freezing points, the dielectric const...
Here’s the complete list of 60 key terminologies for GCSE Chemistry:Atom: The smallest unit of an element, consisting of protons, neutrons, and electrons.Element: A substance made of only one type of atom.Compound: A substance formed when two or more elements chemically combine.Molecule: A ...
they are bright, metallic, and silvery in appearance. The most common oxidation state for most of these elements is +3, although +2 and +4 are also generally stable. Because they can have a variety of oxidation states, they tend to form brightly colored complexes. ...

Keep in mind, this the list of heavy metals includes both natural and synthetic elements, as well as elements that are dense, but necessary for animal and plant nutrition. Noteworthy Heavy Metals While the classification of certain dense metals as heavy metals is debatable, others are noteworthy...
Beryllium is a highly toxic metal so it is not of great practical value and is not researched a great deal. But since it has a low molecular weight it is useful as a window in x-ray spectrometers because it doesn't absorb the X-rays used to detect the heavier elements. Rate ...
Learn the definition of representative elements. Learn about their groups, their blocks, which are metals and nonmetals. See them on the periodic...
As we move from left to right across a period, the number of valence electrons of the elementsincreases and ranges between 1 to 8. Contrast Of Valency or Oxidation State Down A Group While moving down in a group, the number of valence electrons remains constant. Therefore all the elements ...
