Several types of boron exist: amorphous boron is a brown powder and crystalline boron is black and extremely hard. Boron compounds are used in silica-based glasses and ceramics to give them resistance to thermal shock. Boron is more toxic to arthropods and are used as insecticides. Boron is essential to life. Small amounts of boron compounds play a strengthening role in the cell walls of all plants‚ making boron necessary in soils. The name boron originates from the Arabic word ’ buraq’ or borax

Classification of Living Things Classification of living things is called "Taxonomy." This is when scientists put organisms into groups when they have things in common. The first groups they use are the Kingdoms. There are five kingdoms: ➢ Animal Kingdom ➢ Plant Kingdom ➢ Fungi Kingdom ➢ Protist Kingdom ➢ Moneran Kingdom Each Kingdom is then split into smaller groups‚ called Phyla. Each Phylum is split into smaller groups called Classes‚ each Class is split into
