1. Elements in the periodic table are arranged by atomic number. The atomic number increases starting with hydrogen, which only has 1 proton, until you reach the highest atomic number of 106. Elements in each row have similar electronic configurations to the other elements in that row (or period). The elements in the same columns (or groups) have similar chemical reactivity. The electronegativity of the elements increases from bottom to top in a column and increases from left to right across a group. There are also different orbitals that electrons in atoms are arranged in. These are named “s”, “p”, “d”, and “f”. Elements that are in the same group all have the same number of electrons in each orbital. So, the alkali metals in the first column all have a single electron in their outermost shell. This characterization is continued in each group of the table expect most of the transition metals. The elements that are the
