Atomic weights found within a periodic table one might think are constant. The truth is that atomic weights have changed as a function of time. Chemical reactions can be understood by these three areas of focus. ... chemical reactions mostly focuses on the building blocks. More specifically, how they are put together, how they dissassemble, and ways to rearrange them. ... "A" and "B" could represent just two different elements, or they could be compounds (2 or more elements). a mixture of elements can be a compound or simply a mixture. a compound is two or more elements of the periodic table joined together chemically. a mixture is where they are connected but not.

A molecule consists of two or more atoms of the same element, or different elements, that are chemically bound together. Note that the two nitrogen atoms which comprise a nitrogen molecule move as a unit. Compounds Microscopic view of the molecules of the compound water (gas phase). Oxygen atoms are red and hydrogen atoms are white. A substance made of two or more different elements that are chemically joined together. As early chemists worked to purify ores and discovered more elements, they realized that various elements could be grouped together by their similar chemical behaviors. One such grouping includes lithium (Li), sodium (Na), and potassium (K): These elements all are shiny, conduct heat and electricity well, and have similar chemical properties. 1. One of the most abundant elements found in both the universe and the human body; the defining ingredient of an organic compound. Copernicium. 2. Element used in the production of stainless steel as, despite its colourful name, it is a silvery metal that can be highly polished to produce a shiny finish. Caesium. 3.
