In naming aphanetic extrusive rocks, the name is often based only on a few phenocrysts. This is why a mafic name prefix is often used, for example hypersthene andesite. A better name is hypersthene phenoandesite.. a pH value tells us how much H. +. is in a solution. It can be defined by: pH = - log[H. +. ] (log is to base 10). . . (Also note, square brackets are used to denote concentration values); For example: pH = -log[10. The most awesome chemistry tool ever!. Unit Objectives:.

What are Alkali Metals?. The alkali metals are located in Group 1 of the periodic table. They are a series of chemical elements which have similar trends and properties. Alkali metals are so called because when they react with water alkalis (strong bases that can neutralize acids) are formed.. Periodic Table. Periodicity:. regular variations (or patterns) of properties with increasing atomic weight. Both chemical and physical properties vary in a periodic (repeating pattern).. Group:. vertical column of elements (“family”). Lesson Objectives. Understand the relationship between the number of orbitals in various energy sublevels and the length of the periods in the periodic table.. Identify each block of the periodic table and be able to determine which block each element belongs to based on its electron configuration..
