What Is Ununoctium? What is Ununhexium? What is Ununquadium? What is Ununseptium? Discussion Comments Byanon29837— On Apr 09, 2009 Bohrium, the most boring element know to man. Its very shy and doesn't like to hang around. You have to bombard it with Bismuth just to coax it to...
(CMOS) is thesemiconductortechnology used in most of today's integrated circuits (ICs), also known aschipsormicrochips. CMOS transistors are based on metal-oxide semiconductor field-effect transistor (MOSFET) technology. It is called complementary because each element is made up of two transistors ...

A multivalent metal is an element that forms more than one type of an electrically charged particle known as ion.Metals have the tendency to form cations by losing electrons and becoming positively charged. In the periodic table of elements, the transition and the right-most metals are multivalen...
The scientific study of matter's characteristics and behaviour is known as chemistry.andare different from the normal vocabulary. It is a branch of natural science that examines the building blocks of matter, including the atoms, molecules, and ions that make up compounds and their composition, ...
Bismuth is diamagnetic. Magnets repel it. Neon is the least reactive element in the Periodic Table and is used in neon signs. Titanium is very strong and very, very light! Ideas for learning about the Periodic Table Teach Beside Me has an amazingPeriodic Table Battleshipsgame. ...
Nitrogen forms strong bonds with other elements, because its outermost electron shell is lacking three electrons. These bonds make it very stable, which is why it is sometimes used as a buffer gas. Approximately 4/5 of the Earth's atmosphere is made up of nitrogen, and the element is the...
