Do you see how that sodium is the positive ion? Sodium is the metal. Think about this example: When sodium chloride (NaCl) is dissolved in water (H 2O), it breaks apart into sodium (Na+) and chlorine (Cl -) ions. Also, their metallic oxides make hydroxides (bases) (OH -), and not acids, when in solution. Metals usually make positive ions when the compounds are dissolved in solution. A metal like iron (Fe) forms iron oxide (Fe 2O 3), which you know as rust.ģ. Sodium (Na) and potassium (K) are some of the most reactive metals. Reactivity: Metals are very reactive, some more than others, but most form compounds with other elements quite easily. Silver (Ag) and copper (Cu) are some of the most efficient metals and are often used in electronics.Ģ. ![]() ![]() ![]() Conduction: Metals are good at conducting electricity. What are the characteristics of metals? We've got four traits that will help you identify whether an element is a metal or not:ġ. Lucky for you, the periodic table is excellent at organizing elements, and you will find each of these groups in specific areas of the periodic table. Here's a quick list: Actinide Metals, Lanthanide Metals, Alkali Metals, Alkaline-Earth Metals, Rare Metals, Rare-Earth Metals, and Transition Metals. Just remember the ones you might need in class. How many kinds of metals are there? So many. There are other metals like potassium (K) and iridium (Ir) that you might not think about right away. They are not all like silver (Ag), gold (Au), or platinum (Pt). Almost 75% of all elements are classified as metals. GenHydro is shaping a global market for circular decarbonization by providing impactful zero-carbon energy solutions for a cleaner tomorrow.įor more information about GenHydro and to learn more about our technology capabilities and investor opportunities please Contact Us.We wanted to give you a big overview of metals before we get into details about specific families. With thanks to aluminum, the reactive metal essential to our approach, GenHydro is able to efficiently produce three renewable products: renewable energy, clean hydrogen, and alumina (aluminum oxide). Step 4: With a mix of hydrogen, aluminum oxide and excess steam leaving the reactor, the reaction is complete! The excess steam is then recycled to keep the reaction going without any need for additional energy input As this pressure builds and the hydrogen is freed, the now oxidized aluminum is broken into submicron particles and release high levels of thermal energy Step 3: As the steam makes its way through external cracks in the aluminum, hydrogen bubbles begin to form under the surface. Step 2: When exposed to high pressure and high temperature steam, the surface of the aluminum begins to corrode in milliseconds, freeing the hydrogen gas Step 1: Aluminum scrap is milled down to micron sized particles and combined with a chemical promoter that will help assist the reaction How does GenHydro’s reactor system technology work? The oxidized layer on the metal’s surface is not as easy to get around as it may seem, it requires energy and a chemical assist. To release the hydrogen, water needs a way to get beneath the oxidized surface of the metal and reach the metal that has not yet oxidized, that will take the oxygen from the water, and set the hydrogen free. Reactive metals actually take the oxygen from water molecules and leave H2 (hydrogen gas) behind. The process to clean hydrogen and energy continues with bonded hydrogen and oxygen (H2O). The compounds formed by these bonds are known as “oxides.” However, most metals when bonded with oxygen, will not fully form an oxide but will instead create an oxide layer on the surface of the metal that can potentially grow to overtake the entire metal. When oxygen and reactive metals are combined, they form a practically inseparable bond. This process starts with oxygen, the most abundant element on earth, that is also a highly reactive element. ![]() GenHydro has designed, refined and patented a highly cost-effective modality of harnessing this chemical reaction from waste aluminum materials. Generating hydrogen from water through a reaction with aluminum is well-known science that has been practiced as far back as 2008 with the US-DOE. How do reactive metals help us generate emission-free hydrogen?
