Which is highly unreactive element? Group 8A (or VIIIA) of the periodic table are the noble gases or inert gases: helium (He), neon (Ne), argon (Ar), krypton (Kr), xenon (Xe), and radon (Rn). The name comes from the fact that these elements are virtually unreactive towards other elements or compounds. Why is fluorine the most […]
What lasts longer brass or stainless steel?
What lasts longer brass or stainless steel? While a more expensive option than brass, steel is a very durable, resilient metal. While brass is a copper alloy, stainless steel is an iron alloy mixed with chromium and nickel. Steel is also able to work in more temperatures than brass and tends to last longer. What’s […]

Do gases expand to fill their container?
Do gases expand to fill their container? Gases are in rapid motion, and they undergo elastic collisions with each other and the walls of the container; that is, momentum and energy is transfered not lost during collisions. Gases expand spontaneously to fill any container (rapid motion). What gas expands the most? Expansion ratio nitrogen 1 […]
What does the P stand for in P wave?
What does the P stand for in P wave? Compressional waves are also called P-Waves, (P stands for “primary”) because they are always the first to arrive. Shear waves propagate more slowly through the Earth than compressional waves and arrive second, hence their name S- or secondary waves. What happens if the P wave is […]

Anyone who’s even attempted a slip dress around the holidays gets it. Polyester. Synthetic fabrics like nylon tights are moisture-free. Rayon. How do […]
What is the reaction between potassium and chlorine?
What is the reaction between potassium and chlorine? Potassium loses one electron when it reacts with chlorine. This electron is transferred to a chlorine atom to form a chloride ion. In KCl, both ions have full outer energy levels (noble gas configuration). Which element will form an ionic bond with potassium? Explanation: Potassium iodide (KI) […]
