Table II. is in general agreement not only with the optical spectral evidence but also with that in the region of X-rays. As mentioned earlier, we see in X-ray spectra a change in the binding of an electron in the interior of the atom, This takes place when, for instance, by the ...
. Elements with atomic numbers 1 (hydrogen) through 98 (californium) have been found to exist naturally. However, elements with atomic numbers greater than 98 have only been synthesized in laboratories. From left to right, top to bottom, the atomic numbers of the elements in the table ...
The article shares a science teacher's activity to get students comfortable with using the periodic table of elements. She challenges her students to create words out of the atomic symbols. To ensure that real words are used, she requires stu...

Periodic table - Elements, Properties, Periodicity: The periodicity of properties of the elements is caused by the periodicity in electronic structure. The noble gases are chemically unreactive, or nearly so, because their electronic structures are stabl
Kids will be learning chemistry in such a fun way without even realizing it! You’ll love hearing them call out the names of different elements and getting familiar with the structure of the periodic table. You can make your own version of the game and I will show you how!
