The "-ic" suffix is used for the acid that has more oxygen atoms.
Oxoacids containing oxygen use the "-ous" or the "-ic" suffix. Hydro acids use the prefix "hydro-" and the suffix "-ic". There are a few exceptions that end in "-ide" including hydroxide, peroxide, and cyanide. Polyatomic compounds use a different suffix. This printable Periodic Table Game is a great way to work on learning the elements of the periodic table for kids. Using the stock method, a roman numeral is used after the metal to indicate which ion is using the charge. If one of the two compounds is a metal, then the naming convention changes a bit. Here are 23 of the best periodic table activities to get students interested and to help them study this all-important component of science. See below for some of the more complex naming rules. The periodic table is an arrangement of all the elements known to man in accordance with their increasing atomic number and recurring chemical properties.
In a compound that contains iron and fluoride, the metal (iron) would go first.If there are two nonmetal elements, then the first name is the element to the left side of the periodic table. If the compound is made of a metal element and a nonmetal element, then the metal element is first. When there are two elements in a compound, which element goes first in the name? How is the order of the elements determined? Also, this element that makes up air is significant for the survival of all plants and animals. As you can see, oxygen is crucial for the human body. ** note: the "mono" prefix is not used on the first element. They combined to form thousands of compounds. In cases where there is more than one atom (for example there are two oxygen atoms in CO 2) you add a prefix to the start of the element based on the number of atoms. To get the second word we use the name of the second element and change the suffix to "ide" at the end of the word. To get the first word we use the name of the first element, or the element to the left of the formula.
The name of a compound with two elements has two words.
#Periodic table chemistry for kids how to#
The name is built from the elements and the construction of the molecule.įirst we'll cover how to name molecules with two elements (binary compounds). It is a standard method of naming compounds that is used by scientists around the world. You can go here to learn more about molecules and compounds.Ĭhemists have a specific way of naming compounds. A compound is a type of molecule with more than one element. Compounds have their own properties that are unique from the elements they are made of. These bonds are so strong that the compound behaves like a single substance. Chemical compounds are formed when elements are joined by chemical bonds.
