What is the reaction between sodium and oxygen?
Sodium is a very reactive metal, it tends to react with oxygen to form sodium oxide but this is an unstable compound and soon reacts with hydrogen to form sodium hydroxide. Na2O is a sodium oxide formed by the reaction between sodium metal and oxygen of the air at room temperature.
What is the difference between a Type 1 and Type 2 ionic compound?
Type I: Ionic compounds in which the cation has a fix charge. Type II: Ionic compound in which the cation has a variable charge. Cation: Generally a transition metal. The compound forms by atoms sharing electron which means there are no ions in the formula.
What is the difference between naming type 1 and type 2 ionic compounds?
Type 1 binary ionic compounds are those in which the cation has only one form, or charge. Type 2 binary ionic compounds are those in which the cation can have multiple forms. Additionally, binary ionic compounds containing polyatomic ions have another distinct set of naming rules.
Is FeCl2 a Type 1 binary ionic compound?
Examples of type 1 binary ionic compounds are as FeCl2 and FeCl3, AgCl and AgCl2.
What is a Type 1 binary ionic compound?
Type I binary ionic compounds contain a metal and a nonmetal AND the metal that is present only forms one type of cation. Metals with only one cation (shaded below with charges). Both the metal and the nonmetal form ions, which is why it is called an ionic compound.
What is a Type 1 ion?
Binary Ionic Compounds (Type I) The cation (positively charged ion; Na+, Al3+) is always named first and the anion (negatively charged ion; Cl-, O2-) second. A monatomic (meaning one-atom) cation takes its name from the name of the element.
How can you tell if a compound is binary?
A few examples of chemical elements are hydrogen, oxygen, and iron. This means that a binary compound will be composed of two different chemical elements. In a binary compound, there may be only one of each element. We see this with sodium chloride (salt) NaCl, which has one sodium (Na) and one chlorine (Cl).
What is the overall charge on any ionic compound?
zero
What is the purpose of a subscript when writing the formula for a binary ionic compound?
What is the purpose of a subscript when writing the formula for a binary ionic compound? the purpose of a subscript is to show the ratio of the number of compound in the compound.
What is the chemical name for the formula na2s?
sodium sulfide
