Chemistry, the science of the properties, composition, and structure of substances (defined as elements and compounds), the transformations they undergo, and the energy that is released or absorbed during these processes. Chemistry is concerned with the properties of atoms and the laws governing their combinations.

Chemistry recognizes two different types of substances: elements and compounds. Element. An element is the simplest type of chemical substance; it cannot be broken down into simpler chemical substances by ordinary chemical means. There are 118 elements known to science, of which 80 are stable. (The other elements are radioactive, …... -step video playlist.

The radius of the Ca atom is 197 pm; the radius of the Ca 2+ ion is 99 pm. Account for the difference. The lattice energy of CaO ( s) is –3460 kJ/mol; the lattice energy …Chirality. Chirality essentially means 'mirror-image, non-superimposable molecules', and to say that a molecule is chiral is to say that its mirror image (it must have one) is not the same as it self. Whether a molecule is chiral or achiral depends upon a certain set of overlapping conditions. Figure 4 shows an example of two molecules, chiral ...
