Electron configuration is fundamental to the structure of the periodic table. It determines which group in the system different elements belong to. Electronegativity is also a central concept to ...

Physicists have filled in some longtime blank spaces on the periodic table, calculating electron affinities of the lanthanides, a series of 15 elements known as rare earths. Physicists at Michigan ...

Elements that occupy the same column on the periodic table (called a "group") have identical valence electron configurations and consequently behave in a similar fashion chemically. For instance ...

And it is this repetition in the properties of the elements that the periodic table ... decision should come down to electron configuration, which would leave the table as it is, with lanthanum ...

Students will be able to interpret the information given in the periodic table to describe the arrangement of electrons ... At the middle school level, it is not necessary for students to learn about ...

The first version of the periodic table would not come along for more ... problem with this model is the visualization of the electron in a concrete location. In quantum mechanics, the location ...

Rows in the periodic table are called periods. Each period signifies a new energy level or electron shell being filled by the elements. Columns in the periodic table are called groups or families.

When Dmitrii Mendeleev proposed his periodic table 150 years ago ... the anti­matter version of the electron, a dozen or so times a day, as well as an electron about 13 times a second.
