They all have a similar electron configuration in their valence shells: a single s electron. This periodic table contains all 118 elements along with each element’s atomic number, symbol, name, atomic mass, electron shell configuration, and most common charges (oxidation states). Aluminum also presents in some gemstones like topaz, garnet, and chrysoberyl. The melting point of the aluminum is 660 ☌ and the boiling point is 2,467 ☌. The atomic weight of the aluminum is 26.9815. Their electron configurations (abbreviated for the larger atoms) are as follows, with the valence shell electron configuration highlighted: Electrons, electron configurations, and the valence shell electron configuration highlighted. This periodic table is a periodic table with charges PDF optimized to fit on a single sheet of paper. Its compound is mostly present in the form of rocks, vegetation, and animals. For example, take the elements in the first column of the periodic table: H, Li, Na, K, Rb, and Cs. If we look at just the valence shell’s electron configuration, we find that in each column, the valence shell’s electron configuration is the same. The periodic table shows the atomic mass and atomic number of each element. Take a closer look at the some of the elements in the periodic table’s far right column in Figure 3. (The inner electrons are called core electrons.) The valence electrons largely control the chemistry of an atom. The periodic table is arranged in columns and rows based on the number of electrons and where these electrons are located. The electrons in the highest-numbered shell, plus any electrons in the last unfilled subshell, are called valence electrons the highest-numbered shell is called the valence shell. The periodic table is separated into blocks depending on which subshell is being filled for the atoms that belong in that section.
