Immerse the Popsicle stick into the distilled water to fully extinguish it‚ and then discard it into the trash. 2. Repeat step 1 for each of the remaining salts 3. Repeat step 1 for each of the unknown metals and predict the identity of the unknown metals. Repeat any of the known metals to help with this prediction. Observations The salts all burned different colors and all burned for at least ten seconds. The elements with that burned a color with a high energy level on the electromagnetic

Silver is a beautiful‚ soft‚ white‚ lustrous metal thats strong‚ malleable and ductile. It is because of this materials softness that it must be alloyed with base metals like copper‚ as in the case of sterling silver (92.5% silver‚ 7.5% copper). If she’s producing a collection‚ Sceats usually get her ideas from different places around the world or a specific

APPLICATIONS • Decoration: Coating a more expensive metal onto a base metal surface in order to improve the appearance. Applications are jewellery ‚ furniture fittings‚ builders’ hardware and tableware. • Protection: Corrosion-resistant coatings

Because it is located in group one‚ it is one of the most highly reactive and electropositive metals and is a base. Potassium is a solid‚ silvery white metal at 298 Kelvin‚ and has a melting point of 336.53 Kelvin; the boiling point is 1032 Kelvin. Its typical density is 856 kg m3-‚ making it the second least dense metal. Potassium can be found in nature‚ but not alone. It is found in
