Definitions of solute Solvent and Solution

Image
Definitions of solute  Solvent and Solution, Solute: solute may be a substance that may be dissolved by a solvent to form a solution. A solute may be available in several forms. It can be gas, liquid, or solid. The solvent is a substance that dissolves the solute and  breaks the the solute apart and distributes solute molecules equally. This makes a homogeneous mixture (solution) that's same throughout. Example : An example of a solute is sugar dissolving in water. Solvent: solvent is that the element of a solution which is present in the largest quantity. it's the substance in which the solute molecule are dissolved. Example: • The solvent for sugar is water. • Nitrogen is solvent for air. Solution: The homogeneous mixture of two or more  substances is called solution. A solution can be present in any  state. It consists of a solute and a solvent. The solute is that the substance that's dissolved within the solvent. the number of solute mole...

Physical properties of d-block elements

Image
Physical properties of d-block elements Key points: The properties of the d metals are largely derived from their electronic structure, with the strength of metallic bonding peaking at Group 6; the lanthanide contraction is responsible for some of the anomalous behaviour of the metals in the 5d series. The d block of the periodic table contains the metals most important to modern society. It contains the immensely strong and light titanium, the major components of most steels ( Fe, Cr, Mn, Mo ), the highly electrically conducting copper, the malleable gold and platinum , and the very dense osmium and iridium . To a large extent these properties derive from the nature of the metallic bonding that binds the atoms together. Generally speaking, the same band structure is present for all the d-block metals and arises from the overlap of the (n 1)s orbitals to give an s band and of the nd orbitals to give a d band. The principal differences between the metals is...

d-block elements

Image
The metallic elements are the most              numerous of the elements and of the metallic elements the d-block elements are the most important: their chemical properties are central to both industry and contemporary research.   The two terms d-block metal and transition metal are often used interchangeably; however, they do not mean the same thing. The name transition metal originally derived from the fact that their chemical properties were transitional between those of the s and p blocks. Now, however, the IUPAC definition of a transition element is that it is an element that has an incomplete d subshell in either the neutral atom or its ions. Thus the Group 12 elements (Zn, Cd, Hg) are members of the d block but are not transition elements. In the following discussion, it will be convenient to refer to each row of the d block as a series, with the 3d series the first row of the block (Period 4), the 4d serie...
