Periodic Table and Functions Worksheet
Periodic Table and Functions Worksheet The periodic table is a tabular display of the chemical elements, organized on a basis of their properties. Elements are presented in increasing atomic number; while rectangular in general outline, gaps are included in the rows or periods to keep elements with similar properties together, such as the halogens and the noble gases, in columns or groups, forming distinct rectangular areas or blocks. Because the periodic table accurately predicts the properties of various elements and the relations...

Acidic and Basic Nature of Oxides Worksheet A binary compound of oxygen with another element is called oxide. On moving left to right in a period acidic nature of oxides and hydroxides increases and basic nature decreases. Basic nature of hydroxides decreases on moving down the group. Acidic nature of oxides or hydroxides decreases while basic nature increases. (i) Basic oxides: Alkali, alkaline earth and transition metals form basic oxides - etc. their relative basic character decreases in the order :alkali metal oxides>alkaline earth...

Electronegativity and Valency Worksheet The ability of an atom to attract bond pair of electrons in a molecule is referred to as electronegativity. The relative electronegativity is measured by considering: (i) The ionisation energy and electron affinity of the combining atoms. (ii) The energy required to break a bond. (iii) The dipole moment of the resultant molecule. Valency is the power of an atom of an element to combine with other atoms...

Ionization Potential Worksheet Ionization potential or ionization energy is the Amount of energy required to remove an electron from an isolated atom or molecule. There is an ionization potential for each successive electron removed, though that associated with removing the first (most loosely held) electron is most commonly used. The ionization potential of an element is a measure of its ability to enter into chemical reactions requiring ion formation or donation of electrons and is related to the nature of the chemical bonding in the...

Electron Affinity Worksheet Electron affinity reflects the ability of an atom to accept an electron. It is the energy change that occurs when an electron is added to a gaseous atom. Atoms with stronger effective nuclear charge have greater electron affinity. Simply the electron affinity (EA) is the energy required/released to add one electron to an atom. or The electron affinity gives a measure of the tendency of an atom to change into an anion. It may be defined as “The energy given out when an extra electron is taken up by neutral...

Atomic and Ionic Radii The term radius for an atom or ion is usually considered as the distance between the nucleus and the outermost shell of the atom or ion. It is obviously impossible to isolate an individual atom or ion and determine its radius, especially since its size or radius is affected by the association with other particles. It is the distance from the nucleus of an ion up to which it exerts influence on its electron cloud. No doubt the electron cloud may extend to a very large distance. However, it is important to...
