They contain a central nucleus made up of neutral neutrons and positively charged protons. Negatively charged electrons orbit the nucleus.  \n1. Label the diagram of the atom.  \nUse the words in the box.  \nelectron neutron proton  \nAn element is made up of only one type of atom. There are around 100 different elements, which can all be found on the periodic table.  \nA compound is formed when two or more different atoms are chemically bonded together. For example, water (H2O) is a compound made up of hydrogen and oxygen atoms. Compounds can be represented by their chemical formula; this shows the number of atoms of each element present in the compound.  \n2. For each of the substances below, write down the element(s) that it contains. The first one has been done for you.  \nYou might find it helpful to use a periodic table for this question.  \n\n| Name of Substance | Chemical Formula | Element(s) |\n| --- | --- | --- |\n| water | H2O | hydrogen and oxygen |\n| magnesium oxide | MgO |  |\n| carbon | C |  |\n| oxygen | O2 |  |\n| methane | CH4 |  |\n| iron | Fe |  |\n| glucose | C6 H12O6 |  |\n\n1 of 2  \nHomework 1  \n3.
