There is at least one correct example each of an element, a compound, and a mixture. An ST value of −0.5 indicates the absence of the corresponding particle size in the ternary mixture (i.e., a binary mixture of other particle sizes). Elements that compose the compound are chemically combined.

Elements are substances which are made up entirely from one type of atom, regardless of whether the atoms are chemically combined together. All matter is made of particles; these can be single atoms or atoms chemically joined to make molecules.Using this fact, matter can be classified into three broad groups: elements, compounds and mixtures. For more general information see the main page of definitions of elements mixtures and compounds. Mixtures. Image Transcription close. 1.

Pizza is not an element because it is a mixture of many substances. e.g: antibiotics contains tiny solids that settle at the bottom of the container after some time. The properties of a compound are the same as the properties of the elements of which it is made up. The cards may be used at different levels of sophistication. Element 16. You can see that this is, uh, a symbol. Example: Water decomposes into a mixture of hydrogen and oxygen when an electric current is passed through the liquid. Z is 2 diatomic elements.
