First Responder Safety. Course Objectives:. Upon completion of this training, attendees will be able to:. Define the hazardous nature of responding to a chemical suicide call.. List the steps in safely responding to a call involving chemical suicide.. can make a very essential molecule called water once the hydrogen has a covalent bond with oxygen. Hydrogen is the first element on the periodic table. It is also the most abundant element in the univ By:. Luis Martinez. #1 Hydrogen. Hydrogen is the lightest element. . It . is by far the most abundant element in the universe and makes up about . 90. % of the universe by weight. . Hydrogen . as water (H2O) is absolutely essential to life and it is present in all organic compounds. Hydrogen is the lightest gas. Chapter 5.1 . BLM 5.1a, 5.1b. Chemicals and . Chemical . Change.

All substances are made up from tiny particles called atoms. When a substance is made up of only one type of atom it is called an element. The element iron is made up of iron atoms, the element hydrogen is made up of hydrogen atoms, the element sulphur is made up of sulphur atoms and so on.. Information and Uses. Unit 2 - Mission to Mars Connection. Hydrogen is the lightest. and . most abundant element in our universe.. Hydrogen does not exist by itself. in nature. Hydrogen exists as parts of compounds. Manas. . Mahajan. HYDROGEN. . . Hydrogen has the simplest atomic structure among all the element. However, it exist in diatomic (H. 2. ) form in nature and is the lightest and most abundant chemical element, constituting roughly 75% of the universe’s chemical element mass but is still the rarest element on the earth about 0.15% by mass. The name hydrogen is arrived from a Greek HYDRO meaning water and GENES meaning creator.. General definitions. Mole. Homogeneous mixture. Heterogeneous mixture. Pure Substances. Compounds .
