Bruno Darbouret. 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 elements in group 1, on the left of the periodic table, are called the. . alkali metals. ..

The pores can be sealed (closed-cell foam), or they can form an interconnected network (open-cell foam).. The defining characteristic of metal foams is a very high porosity: typically 75-95% of the volume consists of void spaces.. Group I metals Trends Melting and Boiling points? Densities Reactivity… Alkali Metal What is the trend in density? The alkali metals generally become more dense going down the group, but the trend is not perfect because potassium is less dense than sodium. . SYFTET.
