which atom has the smallest atomic radius: phosphorus or sodium

The distance from the nucleus to the outermost shell depends on the electrostatic attraction (nuclear charge) that the nucleus exerts on the electrons of the outer shell. More the nuclear charge closer are the shell and electrons, hence smaller is the atomic radius of an at..

Formation of Molecule Atoms of most of the elements do not exist independently. They either form molecules or ions. An atom having a charge on it is called an ion. When an atom loses or gains charge, it gets converted into a positively or negatively charged ion res..

Electronegativity is the tendency of an atom to attract electrons towards itself in a molecule of a compound. The value of electronegativity of an element describes the ability of its atom to compete for electrons with the other atom to which it is bonded. Electronegat..

Elements - "An element is a pure substance which is made up of only one kind of atoms having the same atomic number." "The smallest particle of an element is the atom which, has all the properties of that element." "An element cannot ..

For example, lithium displays an anomalous behavior when compared to sodium and rest of the family members of the alkali metal family. The difference between the first members from its succeeding members is highlighted with lithium as a representative example, The first member of each g..

John Alexander Reina Newland was a chemist as well as a lover of music. Newland arranged many of the known elements in the increasing order of their atomic masses. He started with the element having the lowest atomic mass (hydrogen) and ended at thorium which was the 56 th ..
