Many compounds consist of molecules which are discrete groupings of atoms in a definite geometrical arrangement. A suitable explanation at Key Stage 3 is that a compound contains two or more elements bonded together in fixed proportions. A compound usually has different properties from the elements from which it is made. For example sodium metal is a reactive metal and chlorine a toxic gas, but combined together they make sodium chloride which is added to food to preserve it or to enhance the flavour. Substances such as glass, steel, iron oxide, plastics and starch are compounds too but the proportions of elements making them up can vary. In each case atoms are attracted by all the adjacent atoms making them nearly uniform solids.

To measure these waves we use the fact that a neutron passing though a material will interact with the atoms of the material and create a wave … Read More

Many employers will ask for letters of reference, so take them alongside on your interviews for science careers or send them forward if requested. You need to begin gathering them earlier than you start the job search process.

Although many STEM careers are male-dominated, some — such as accounting and health-related occupations — employ more girls. And right now, many traditionally male-dominated fields are actively recruiting ladies.

Sedimentologists work carefully with geologists and other earth scientists in amassing and analyzing data concerning the pure world. As the name suggests, they research sediments from dry land and wet land together with rivers, marshes (salt and recent water) swamps, and from ocean tidal ranges the place there may be soil or silt.
