How does the arrangement of elements on the periodic table allow for the prediction of undiscovered elements and their properties?

Answer 1

A lot of the common properties of elements come from their atomic structure -- in particular, the arrangement of their electrons. Chemists have determined that electrons in a stable element tend to develop layers of orbits in a predictable pattern. The Periodic Table is structured to organize the elements along these patterns.

The rows of the table shows the basic progression of these electron orbit periods (thus the term "periodic table", while the columns group the elements by the common properties expressed through their electron configurations. For example, the rightmost group of the table is composed of the "noble gases", the most stable of the elements. These elements have complete stable electron groups and are thus nonreactive.

With the sixth and seventh rows, the number of electrons that can exist in a layer extends beyond the ability of the table to display them properly. Thus the addition of the Lanthanoid and Actinoid rows below the bottom of the table (named for the first elements in their respective rows).

Answer 2

Well, it's actually not the law that can tell you that, it's what group the element is in. So if two elements are in the same group, that will probably mean that they will have similar physical and chemical properties.

Answer 3

The periodic table helps predict some properties of the elements compared to each other. Atom size decreases as you move from left to right across the table and increases as you move down a column. Energy required to remove an electron from an atom increases as you move from left to right and decreases as you move down a column. The ability to form a chemical bond increases as you move from left to right and decreases as you move down a column.

Answer 4

Because the periodic table is organized by atomic number which shows the amount of electrons in number order.

Answer 5

they predict the properties of elements, by saving your mum.

YES MATE THAT IS TRUE

Answer 6

The position of a chemical element in the periodoc table (period, group, atomic number) give several informations about the physical and chemical properties for elements.
