The identification of the sectors covered by the project "Defining and Strengthening Sector Specific Sources of Competitiveness" (the SSSC project) was carried out based on the Sector Prioritisation Framework (SPF) methodology. This approach is based on a three-step process involving stakeholder ...
Chapter 4: The Structure of Matter Section 4.1 Compounds and Molecules What are compounds? A substance made of atoms of more than one element. When elements form compounds, they have different properties than the elements that formed it. Chemical Bonds distinguish compounds from mixtures. Chemical ...
