Chemistry Atomic Structure: The Electron A myriad of trends occur on the periodic table‚ whether it is defined through the size of the atoms or the first ionization energy that may occur‚ many other trends can be found simply looking horizontally or vertically on to the table. As you look from left to right you can see that the reactivity of the elements increase‚ this is due to the number of electrons increasing on the shell. This also once you go down the table; the shells become further and

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
