Boron is a metalloid that means it has the intermediate properties of metals and non - metals both and it comes under the category of p-block elements. It is present in the solid state and its appearance looks shiny and brittle. It is a good conductor of heat as well as electricity also at high temperatures.Note: Number of electrons always equal to the atomic number of an atom only in the neutral state, but whenever an atom is present in the form of ion then number of electrons varies from the atomic number.Recently Updated PagesWrite a brief account of abscisic acid class 11 biology CBSEPhotolysis of water involves a Excitement of water class 11 biology CBSEBoth wind and water pollinated flowers are not very class 11 biology CBSEWhich among the following has specialized tissue for class 11 biology CBSEGive one point of difference between the notochord class 11 biology CBSEWhat are the factors that are essential for photos class 11 biology CBSEWrite a brief account of abscisic acid class 11 biology CBSEPhotolysis of water involves a Excitement of water class 11 biology CBSEBoth wind and water pollinated flowers are not very class 11 biology CBSEWhich among the following has specialized tissue for class 11 biology CBSEGive one point of difference between the notochord class 11 biology CBSEWhat are the factors that are essential for photos class 11 biology CBSE
