First, you should determine the geometry of the molecule. How many atoms or lone pairs are associated with the central atom? Is the molecular geometry linear, trigonal planar, tetrahedral, etc. Secondly, you need to determine the electronegativity of the atoms bonded together in the molecule. Polarity is all about electronegativity and how tightly bound electrons are to particular atoms in a molecule. Lone pair electrons on the central atom are obviously quite electronegative and should be accounted for as such. Halogens and other extremely electronegative atoms will provide a strong negative charge due to their affinity for electrons. If the molecule is symmetrical it is to be expected to be non-polar, and if it is asymmetrical it would be expected to be polar, but this is not always the case. For instance, a water molecule is symmetrical, but it is polar due to the pull of the lone pair electrons of the oxygen atom.
CBr4 is non polar in structure and nonpolar in bonding while finding the difference of electronegativity
The significance of the ninety percent contour is to determine the probability of finding the most electrons within a region.
Brass is homogeneous. To test this, I'm still finding it. But brass is homogeneous.
Titration can be used to make sure that the base used in these tasks are standardized. This is important in finding out which antacid is the best because all the bases will have the same impact.
The location in three-dimensional space of the nucleus of each atom in a molecule defines the molecular shape or molecular geometry. Molecular shapes are important in determining macroscopic properties such as melting and boiling points, and in predicting the ways in which one molecule can react with another. A number of experimental methods are available for finding molecular geometries, but we will not describe them here. Instead we will concentrate on several rules based on Lewis diagrams which will allow you to predict molecular shapes.To provide specific cases which illustrate these rules, "ball-and stick" models for several different types of molecular geometries are shown in Table 1. The atoms (spheres) in each ball-and-stick model are held together by bonds (sticks). These electron-pair bonds determine the positions of the atoms and hence the molecular geometry.
The mode is the most probable value. Often, you determine the mode by plotting the experimental probability distribution, and finding the peak value. The mode is not necessarily the same as the mean nor the median, unless the distribution is symmetrical.
