Difference between Nuclear charge and Effective Nuclear charge – Digital Kemistry

What is the nuclear charge in the periodic table? The nuclear charge (Z) is defined as “the total charge in the nucleus due to the presence of positive charge protons”. As we move through the periodic table, the atomic number continuously increases due to the increase in the number of protons in the nucleus, thus …

Trends in Chemical properties of elements in period 3 – Digital Kemistry

Trends in Chemical properties of elements in period 3 : Period 3 of the table consists of Sodium, Magnesium, Aluminum, Silicon, Phosphorus, Sulphur, Chlorine and Argon. They can be roughly divided into metals (Na, Mg and Al), metalloids (Si) and non-metals (P, S, Cl, and Ar), and therefore the elements within these groups tend to …
