Only a neutral atom possesses an equal number of protons and electrons, the atomic number of an element is equal to the number of electrons in the neutral atom, not in the ion. An ion, on the other hand, is gen

The abundance of each type of isotope is taken into account when calculating the average atomic mass, or the atomic weight, which is found on the periodic table. After watching this lesson, you should be able to recognize how isotopes are variations of the same element, and how that's ...
The Periodic Table places the symbols of chemical elements, sequenced by atomic number , in rows and columns that align similar properties. Antiquity through the Renaissance A few thousand years ago, primitive chemistry focused mostly on converting one substance into another. The word "chemistry" ...
