Their full name is like the substances name and their nickname is like the substances formulae.

Without these names your friends would have no idea which of them you are referring to. We simply use the names that we find on the periodic table for elements and we use words to describe mixtures. In the example of iron sulphide that was used earlier, the compound name is a combination of the names of the elements but slightly changed.

One of the major research themes in the National Bureau of Economic research is sources of inequality.

Chay, Jonathan Guryan, and Bhashkar Mazumder conducted a study in which they analyzed the substantial gaps in test scores on the AFQT and NAEP tests among black-white cohorts....

About 20 percent of them do not exist in nature (or are present only in trace amounts) and are known only because they have been synthetically prepared in the laboratory. The number of possible compounds is almost infinite; perhaps a million are known, and more are being discovered every day.

When two or more elements combine to form a compound, they lose their separate identities, and the product has characteristics quite different from those of the constituent elements.

For example in nitrogen dioxide () there are two oxygen atoms for every one atom of nitrogen.

Later, when we start looking at chemical equations, you will notice that sometimes there are numbers before the compound name.

Each student then does some initial research on their element and fills in a ‘dating profile’.

This involves them finding out about appearance and uses, as well as drawing atomic structure to show electron shells.

Now in the usual speed dating format, ask metals (or non-metals) to sit at desks whilst the others circulate round with their profiles.
