PPT-Alkali Metals By Ayaana

Patel Sikora 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. Carbonates, Oxides and Hydroxides and their reaction with ACIDS. What is an indicator?. An . indicator. is a chemical that turns a different colour depending on whether it is added to an acid or an alkali.. Physical Science. Elements and their Properties. At room temperature, most metals are . ____.. gases. liquids. radioactive. solids. The process by which solid iodine particles change directly to gas without first becoming a liquid is called . Michael Bailey & Marlena . Artis. Atomic Mass. Symbol. (Uranium). Atomic Number. The atomic number is the number of protons an atom has. The atomic mass is the atom’s mass often measured in AMUs (Atomic mass units) which weighs approximately 1/12 the mass of a carbon-12 atom.

The alkali metals generally become more dense going down the group, but the trend is not perfect because potassium is less dense than sodium. Periodic Table. B. 2p. 1. H. 1s. 1. Li. 2s. 1. Na. 3s. 1.
