Is potassium metal dangerous?
Contact with solid Potassium can cause severe burns. * Exposure to Potassium fumes can irritate the nose, throat and lungs with sneezing and coughing. * Prolonged exposure to Potassium fumes can cause sores of the inner nose. * Potassium is a FLAMMABLE and REACTIVE chemical and a FIRE and EXPLOSION HAZARD.
Is Potassium a metal explosive?
Potassium Metal Is Explosive— Do Not Use It! The reaction of sodium with water is a spectacular and es- sential classroom demonstration. We propose not to do so because explosions can happen even before the metal is in contact with water.
Why is potassium explosive?
On the one hand, the chemistry is clear: The highly unstable pure sodium or potassium wants to lose an electron, and this splits the water atom, producing a negatively charged hydroxide ion and hydrogen and forming an explosive gas that ignites. …

Is lead shiny or dull?
Characteristics: Lead is a bluish-gray, soft, dense metal that has a bright luster when freshly cut. It tarnishes slowly in moist air to form a dull gray coating. The metal is highly ductile and malleable.
Is sulfur dull and brittle?
Sulfur is a non-metal because it’s not placed in metal group in the periodic table. In addition, since Sulfur is dull and brittle in a solid form, it again explains why it is a poor conductor, because it is harder for electrons to move around when they are packed tightly as a solid.
