WebA period 7 element is one of the chemical elements in the seventh row (or period) of the periodic table of the chemical elements.The periodic table is laid out in rows to illustrate recurring (periodic) trends in the chemical behavior of the elements as their atomic number increases: a new row is begun when chemical behavior begins to repeat, meaning that … WebFor each element the atomic weight is on the periodic table right under the symbol of the element. The carbon atomic weight is 12 units of atomic mass (amu), so the weight of one mole is 12 grams. A sample consisting the atoms of a single element, weights the sample in grams and separates the element by its atomic weight.
