A Lewis electron dot diagram (or electron dot diagram or a Lewis diagram or a Lewis structure) is a representation of the valence electrons of an atom that uses dots around the symbol of the element. The information contained in this document is based on the state of our knowledge at the time of publication and is believed to be correct, but does not purport to be all inclusive and shall be used only as a guide. Nitrides: The nitrides of the alkaline earth metals react with water to form ammonia and the oxide or hydroxide of the metal and therefore may cause irritation and/or burns to moist tissue and mucous membranes. You are not right. Obtain medical help for persistent irritation. Reactivity: Beryllium nitride reacts rapidly with air at 600 oC to give BeO and N2. Beryllium oxide is widely used in industry due to its low density and high thermal and electrical conductivity. Appropriate Engineering Controls: Whenever possible the use of local exhaust ventilation or other engineering controls is the preferred method of controlling exposure to airborne dust and fume to meet established occupational exposure limits. Seek medical attention. Eliminate all sources of ignition. Specific Hazards Arising from the Material: May emit toxic fumes of beryllium oxide under fire conditions. Use vacuum and wet cleaning methods for particulate removal from surfaces. Hazardous Decomposition Products: Beryllium oxides, ammonia. Do not use compressed air, brooms, or conventional vacuum cleaners to remove particulate from surfaces as this activity can result in elevated exposures to airborne particulate.

Treat skin cuts and wounds with standard first aid practices such as cleansing, disinfecting and covering to prevent wound infection and contamination before continuing work. The key is to understand the steps and practice. Protect from moisture. Lewis structures extend the concept of the electron dot diagram by adding lines between atoms to represent shared pairs in a chemical bond. Never induce vomiting or give anything by mouth to an unconscious person. Every chemistry student has to learn how to draw Lewis Dot Structures. Isolate spill area and provide ventilation.
