Matter and its Properties Basic Building Blocks of Matter The fundamental building blocks of matter are atoms and molecules. These make up elements and compounds. An atom is the smallest unit of an element that maintains the properties of that element. And element is a pure substance made of only one kind of atom. A compound is the substance that is made from the atoms of two or more elements that are chemically bonded. Water is an example of a compound because it is one of many compounds that

Introduction‚ aim and hypothesis Chemical reactions are accompanied by the release or absorption of energy. Reactions which release energy are described as exothermic and those which absorb energy are endothermic. The energy released in chemical reactions was previously stored as chemical potential energy in the reactants; this stored energy is called enthalpy. The aim of this practical is to observe and classify chemical processes as endothermic or exothermic‚ based on the changes in temperature

I was assigned was the element Manganese. The symbol for manganese is Mn. It is number 25 on the periodic table. That means it has 25 protons and electrons even on mars or anywhere you go it will have the same protons and electrons. The atomic number would also be 25. It has 30 neutrons also in in the nucleus. The melting point for Manganese would be 1519 K (1246°C or 2275°F). The boiling point would be 1519 K (1246°C or 2275°F) according to http://education.jlab.org/. It also could be 1245.0 °C
