There is no testing to predict the severity of an anaphylactic reaction, though a previous severe reaction raises the risk of a subsequent severe reaction. Uncontrolled asthma is a consistent risk factor for severe anaphylaxis and fatal anaphylaxis.
Boron, B belongs to the semiconductors(metalloids) family. Semiconductors are located toward the right side of the periodic table.he Boron family is classified as Metals and Metalloids. They are Group 13 and have 3 valence electrons. The Boron family are solids at room temperature and they are reactive. â¦ But, the most reactive are the Alkali Metals. They have a violent reaction with water. Hope this helps!
Start by writing the complete electron configuration of boron, #B#. Boron is located in period 2, group 13, and has an atomic number equal to #5#. This means that the electron configuration of a neutral boron atom must account for a total of #5# electrons. The complete electron configuration for a boron atom will look like this #B:  1s^2 2s^2 2p^1#
