The periodic table is organized according to trends in element properties. As you move from left to right across a row of elements, the atomic radius (the size of an element's atoms) decreases, ionization energy (the energy required to remove an electron from an atom) increases, electron af...

Leach, M. (2013). Concerning electronegativity as a basic elemental property and why the periodic table is usually represented in its medium form. Found Chem., 15, 13 - 29.M. R. Leach, Concerning electronegativity as a basic elemental property and why the periodic ta- ble is usually ...
The periodic table is a graphical layout that not only gives information about individual elements, but also elements that have similar properties. The seven rows in the periodic table are known as thePeriods. Each element in a particular row has the same number of electron shells surrounding the...

But there are doubts over whether the periodic table is in the best possible configuration. Just as notes can be arranged in various ways to produce music, so the essence of the relationships between the elements could be depicted differently. There is no easy way to judge which is bet...
Why is atomic number more important than atomic mass? Why would the atomic number be better to identify an element than the atomic mass? Why is hydrogen atomic number 1? Why is the periodic table arranged by atomic number? Why do protons contribute to the atomic number?

For example, tellurium comes before iodine in the periodic table, even though its atomic mass is slightly greater. Such anomalies are due to the relative abundance of the "isotopes" or varieties of each element. All the isotopes of a given element have the same number of protons, but differ...
To find the number of valence electrons: Find the element in the periodic table Read the label at the top of the column it is found in - look for the number that accompanies the “A” label That number IS the number of valence electrons the element has. Example: C is in column 4A ...
