There are 7 known elements with full electron shells, six of which are referred to as noble gases because they are, generally, unreactive with other elements because of their full electron shells (their full electron shells make them resistant to forming bonds with other atoms to form molecules): Helium, Neon, Argon, Krypton, Xenon, and Radon. Ununoctium (element 118) also has a full electron shell, but due to relativistic effects is believed to be a solid at room temperatures (if there were enough atoms of it; it is extremely unstable with a half-life of less than a tenth of a second) so may not be considered a noble gas (all the other known elements with full electron shells are gases at room temperature) but, discounting radioactive decay which causes Ununoctium atoms to fission into lighter, reactive ones, is not chemically reactive with other elements.

Cr2o3 is which magnetic material?
I do not understand your question. Are you referring to what element Cr is? If so, it is chromium. The full name of Cr2O3 is chromium oxide. If you are looking for valence electron levels use the SPDF valence shell ranges.
The last of the noble gases?
Because the periodic table goes by atomic number, and they all happen to line up at the end of the table. In more detail, the chemical properties and electron configurations of the elements determine the arrangement. The noble gasses all have a full valence shell, so they are placed at the end of the table to indicate.
What is the name of the family that has elements that have a full outer shell?
This is the noble gases familiy.
What information is included in each square of the periodic table of elements?
Each column will generally have the symbol of the element (sometimes name of the element also), the atomic number, the mass number, the state in which the element is present at room temperature. Some periodic table will also have the electronic configuration or electronegativity.
What is the full name of the element that hepls create the earths magnetic field?
iron

What is another name for the electron shell?
Orbital x ray
What is the name given to the electron shell that contains the most reactive electrons?
It is the valency shell.
Where is a electron?
In atoms. More specifically, they orbit the nucleus of an atom, in the aptly name electron cloud. Or electron shell.
What was Art Shell's full name?
Arthur Art Shell
What is the proper chemical name for helium?
Helium is an element. It is a Noble Gas (group 8) which means it has a full outer shell and is not reactive. It's symbol is He.
What is the name of element 45?
The element with atomic number 45 is Rhodium (Rh). Rhodium is a transition metal in Group 9, Period 5 of the Periodic Table. Rhodium has 45 electrons in 5 shells with 1 electron in the outer shell.
What is the name and location of the electron responsible for chemical behavior?
outer electron shell, as shown by the grouping on the periodic table.
What is the name of the element with a valence electron configuration of 3s23p3?
The electron configuration of phosphorus is [Ne]3s2.3p3.
Name given to electron shell that contains the most reactive electrons?
Valence
What is the name of the chemical with the symbol He?
It is the short form for Helium, one of the noble gases with an octet electron shell. Helium is the element with atomic number 2. It is a colorless, odorless, tasteless non-toxic gas. Next to hydrogen, it't the second most abundant element in the universe.
What is the name of the element with a valence electron configuration of 2s22p4?
All of the elements in the Alkaline Earth Metals group have the valence shell electron S2. -Hope this helps
