Remember that the second word ends in -ide. CO is a compound of carbon and oxygen Co is the element cobalt. That name tells you that you have one carbon (C) atom and one oxygen (O) atom (you can also use the prefix MONO to say one atom).
Most simple compounds only have two words in their names.
Let's put these ideas together! Remember, we're only talking about simple compounds with no metal elements.
The naming system in chemistry works the same way! You may know about a pentagon, a hexagon, or an octagon. So when you have three chlorine atoms, you would name it trichloride. It's like this.ĭo you notice anything about the chalkboard? You can see that the prefixes are very similar to the prefixes of geometric shapes. When you are working with non-metals like oxygen (O) and chlorine (Cl), the prefix (section at the beginning of the word) of the second element changes based on how many atoms there are in the compound. The second word tells you the second element and how many atoms there are in the compound. The first word is the name of the first element. When you have two different elements, there are usually only two words in the compound name. Examples include carbon dioxide (CO 2), water (H 2O) and ethanol (C 2H. There are some advanced ways of naming things that we're going to skip right now. type of chemical or molecule as either an element, a compound or a mixture. We're going to show you some of the basics. The technique used depends on the nature of substances which make up the mixture.The process of naming compounds is just a set of rules. Mixtures can be separated by filtration, distillation, crystallisation or chromatography. Unlike elements and compounds, which have fixed melting and boiling points, mixtures will melt and boil over a range of different temperatures, as each component of the mixture will change state at different temperatures. Other examples of mixtures include cake batter and shampoo. Air is a mixture, as it is made up of nitrogen, oxygen and argon (all elements) along with carbon dioxide and water vapour (compounds). MixturesĪ mixture is a group of different elements or compounds which are not chemically bonded together. Examples include carbon dioxide (CO 2), water (H 2O) and ethanol (C 2H 5OH), which are all made up of two or more types of atoms bonded together. CompoundsĬompounds are made up of more than one type of atom chemically bonded together. It belongs to group 9, periodic number 4 of the periodic table. Cobalt is a chemical element with Co as its symbol. Notice that all of these things are only made up of a single type of atom. Answer (1 of 5): Co stands for Cobalt on the periodic table. Elements include oxygen molecules (O 2), helium atoms (He) inside party balloons and hydrogen molecules (H 2) in the Sun's core. Element (or chemical element) is the simplest form of matter we find in nature that. These blocks are named for the characteristic spectra they produce: sharp (s), principal (p), diffuse (d), and fundamental (f). Elements are organised into blocks by the orbital type in which the outer electrons are found. An easy way to determine whether something is an element is to see if it appears on the Periodic table, as all elements can be found there. Carbon monoxide is a compound of 1 atom of Carbon and 1 atom of Oxygen. The atomic number of each element increases by one, reading from left to right. An element is a substance made up of only one type of atom.
