PASSAGE - 3 : In modern periodic table there is gradation in the properties of elements. In a period the Ionisation energy, Electron affinity, Electro negativity, Non-Metallic nature increases. In a group the atomic size, metallic nature, reducing properties and densities of elements increases. The pair of elements with equal electro negativities

In the modern periodic table, the elements are placed in order to increasing atomic number. These have been numerous designs of the table over the years but the most common is the long form of periodic table. The long form of periodic table shows all the elements in numerical order. What is the atomic number of the (as yet undiscovered) alkali earth metal after radium?

PASSAGE - 2 : In periodic table there are nearly 110 elements are present majority of elements are present in solid state. There is no separate placement for isotopes of elements in periodic table. The atomic weight of an element is the average atomic weight of isotopes. The element which exhibits highest number of stable isotopes

In the modern periodic table, the elements are placed in order to increasing atomic number. These have been numerous designs of the table over the years but the most common is the long form of periodic table. The long form of periodic table shows all the elements in numerical order. Write the expected ground state electronic configuration of the element with one unpaired 5p electron that forms a covalent compound with fluorine.
