Describe how allotropes of silicon differ in appearance?
Silicon allotropes can range from dark brown to black in appearance. Amorphous silicon appears as a dark brown powder or a shiny black solid, while crystalline silicon forms shiny, gray-colored crystals.
What is the symbol for silicon-29?
The chemical symbol for the element Silicon is Si. If you wanted to distinguish Silicon 29 from other Silicon isotopes you would write 29Si.
Which of the following would be classified as a metalloid A aluminum B copper C tin D silicon?
Silicon is classified as a metalloid.
How many grams of silicon would there be in a sample that contained 9.99 x 1025 atoms?
To determine the grams of silicon in the sample, you need to know the molar mass of silicon. Since silicon's atomic mass is approximately 28 g/mol, you can calculate the grams of silicon by dividing the number of atoms by Avogadro's number and then multiplying by silicon's molar mass. This calculation would provide you with the amount of silicon in grams in the given sample.
What Bond is sih3br?
SiH3Br is the chemical formula for silicon bromide. Its name would be silicon(III) bromide, as silicon typically forms compounds with a +4 oxidation state.
What statement describe a chemial property of silicon?
Silicon reacts with fluorine
