In the periodic table of elements, francium is located in the bottom left corner of the table. It is in the first column, or group, and that represents how many valence electrons it has. Valence electrons are electrons on the outer most energy level of an atom. For francium, it only has one valence electron. It is in the 7th row going down and the rows are called periods. The period an element is on determines the number of energy levels it has. Since Francium is in the 7th row, it has seven levels of electrons. Also, it is a metal because its is left of the zigzag line and also a alkali metal because it is in the first column. Hydrogen is not a alkali metal even though it is in the first column, or group. Also, since it is the element that is the most away from the stair case it is the most reactive metal. Also, it means that it is the most metallic metal. It you look at the picture, there if “Fr” and bunch of number around it. The two letters, “Fr” represent francium and is just a symbol for the element. Then, the bold letter is most likely the atomic number. The atomic number is the number of electrons the element has. It is always is the number of a neutral atom has, or no charge, because there are many ions, or positively charged or negatively charged atoms. Then, you will find a number bigger then that, which is always bigger then the atomic number. That number is the atomic mass, or amu, of the element. The atomic mass is the average of all the isotopes, or different weighing atoms of the same element, and is the weight of one atom.
