The elements to the right of a noble gas have one extra electron, the elements directly on the left need one electron to fill their outer shell. Ok, what does this chart show better then the traditional table? 1. The reactivity of the elements. The elements closest to the noble gases ...
PeriodicTable By JQ Soft ( Free ) Simple periodic table of chemical elements.Features:1) 118 elements2) Atomic, thermodynamic, material, electromagnetic, nuclear properties and reactivity for each element3) Electron shell diagram for each elementTested devices:1) Smartphones with resolution 800x480,...
Each row is called a period. Each period corresponds to the number of electron shells the element has. The first shell has 2 electrons in the shell, so there are 2 elements in the first row. The second and third shells have 8 electrons, so there are 8 elements in the second and third...

"The [above] modern periodic table is simply an orderly array of the elements with all unnecessary ornamentation omitted, has been found highly satisfactory for instructional purposes. "The transitional elements, with two unfilled electron shells, are separated from the non-metallic elements. "The...
Electrons are found in different spaces around an atom, which we call electron shells. Each row of the Periodic Table of Elements, called a period, represents a new outer shell of electrons. The elements in each column, called a group, have the same amount of electrons in their outer shell...

The rows of the periodic table are calledperiods. Anelement's period numberis the highest unexcited energy level for an electron of that element. Columns of elements help to distinguishgroupsin the periodic table. Elements within agroupshare several common properties and often have the same outer ...
Blocks are sections of the periodic table that indicate the outer electron subshell of the atom. The s-block includes the first two groups (the alkali metals and the alkaline earths), hydrogen, and helium. The p-block includes groups 13 to 18. The d-block includes groups 3 to 12, which...
