What Are The Difference Of Modern periodic table, Electron Gain Enthalpy, negative electron gain enthalpy. Variation of electron gain enthalpy in group and period
The figure shows the relationship between the inverse of the lowest magnetically allowed dd* excitation energy (calculated with SAC-CI method) and the observed 95 Mo chemical shifts. We see very beautiful linear relationship.[4]doi:10.1016/B978-0-08-003810-0.50004-1A.E. Somerfield B.Sc, Ph...
It's theoretically possible toextend the periodic table even furtheras chemists synthesize increasingly heavier elements, so the periodic table may never be complete. These manmade elements are created using particle accelerators thatsmash atoms and subatomic particles together, generating nuclei with extra...

Periodic Table of Elements - The periodic table is the tabular arrangement of all the chemical elements on the basis of their respective atomic numbers. In the periodic table, the vertical columns are called groups and the horizontal rows are called peri
Valency:In the periodic table elements the valency increases from one to seven in period with respect to hydrogen but with respect to oxygen it first increases one to four and then decreases to zero. Valancy of sodium, potassium is one. For alkaline earth metals, valency is two and for alum...
The periodic-table position of cesium is in period 6 of group 1. The elements found in group 1 are also known as the "alkali metal" elements, due to their ability to react readily with water to form strong basic (i.e., alkali) solutions. Also, each of the six chemical elements in ...
