An element is a fundamental item that can't be easily broken into smaller pieces. In chemistry and physics, an element is a substance that can't be broken down by non-nuclear reactions. In computing and mathematics, an element is a distinct piece of a larger system or set. Elements in ...
... in terms of Chemistry ? Matter can be classified in various ways according to its structure, behaviours and physical and chemical properties. The main classifications of matter include the categories element and compound, either of which may also be called a substance (which is a less speci...
In chemistry, a compound is a substance made up of two or more different chemicalelementscombined in a fixed ratio. When the elements come together, they react with each other and form chemical bonds that are difficult to break. These bonds form as a result of sharing or exchangingelectronsb...
Atoms are the smallest particles of an element that have the chemical properties of that element. Atoms are therefore extremely small (the hydrogen atom is the smallest) and are sometimes described as the "basic building blocks of matter". This description makes more sense the more chemistry ...

“As a distribution leader, it is my role basically to ensure that we follow all our SOPs and quality guidelines. It is very important, everything from the maintenance of the temperature of our facility, including the cold box where we're standing in now, all the way through how ...
In multiplexing, you can reduce the amount of sample required for a qPCR reaction by measuring the expression of more than one gene in a reaction. The process is as sensitive and accurate as single-gene amplification (or singleplexing), but more technically complex...
It seems reasonable to expect chemistry to provide an unambiguous definition The meaning of an ‘element’ is a favourite topic for argument among off-duty chemists. We agree (right?) that hydrogen is an element – but what do we mean by that? Is molecular hydrogen gas an element? Or the...
