What are the three properties of metalloids? Physical properties of metalloids are as follows: ▪️Metalloids have a solid state of matter. ▪️In general, metalloids have a metallic luster. Metalloids have low elasticity, they are very brittle. ▪️Middleweights are semi-conducted elements, and they allow leave the average transmission of heat. Is sulfur dull or shiny? Appearance […]

Who created the law of conservation of charge?
Who created the law of conservation of charge? William Watson At what point of a closed circuit conservation of charge is valid? Kirchhoff’s second law, also known as the Kirchhoff’s voltage law (KVL) states that the sum of all voltages around a closed loop in any circuit must be equal to zero. This again is […]
