Is Diamond an element?
Diamond is a form of the element carbon with its atoms arranged in a crystal structure called diamond cubic. At room temperature and pressure, another solid form of carbon known as graphite is the chemically stable form of carbon, but diamond almost never converts to it.
Are Diamonds mixtures?
Diamond is an element. It is not a compound as compounds contain several elements. Additionally, diamond is not a mixture since a mixture is either a solution or a mix of various elements in unequal ratios.
Is gold a mixture?
b) 14-karat gold is an alloy of gold and other metals such as copper and silver. Alloys are homogeneous mixtures. Pure gold is referred to as 24-karat gold. Thus it is a mixture.
Is sand a mixture?
Sand is a mixture. Sand is classified as a heterogeneous mixture because it does not have the same properties, composition and appearance throughout the mixture. A homogeneous mixture has a uniform mix throughout.
What is the symbol of diamond?
The element in diamond is carbon so chemical symbol of diamond is C. Diamonds, particularly high quality ones, are very pure carbon.
What is the structure of diamond?
Diamond is a giant covalent structure in which: each carbon atom is joined to four other carbon atoms by strong covalent bonds. the carbon atoms form a regular tetrahedral network structure. there are no free electrons.
