Whereas while moving down a group in the periodic table, the atomic size increases thereby causing a decrease in the value of electron gain enthalpy. The first electron affinity is always exothermic that is …

Periodic properties of elements The basic law governing modern periodic table states that the properties of elements are periodic functions of their atomic number. These properties reappear at regular …

Periodic Trends in the Electronegativities of Elements As we move across a period from left to right the nuclear charge increases and the atomic size decreases, therefore the value of electronegativity …

Ionic radii, what is it? Let’s figure out what we mean by ionic radii and their variation in groups and periods of the periodic table (modern eriodic table). What is Ionic Radius? Ionic radius is the distance …

However, the rest of the d-block elements are somewhat similar in properties and this similarity can be observed along each specific row of the periodic table. These properties of the transition elements …

The modern periodic table of elements can be broken down into 4 blocks – the s-block, the p-block, the d-block, and the f-block. This classification is based on the types of orbitals that contain the valence …
