What is the correct name for compound Cr2O3?
For ionic compounds such as the one mentioned above, naming them is relatively easy. As we all know, an ionic compound consists of a metal ion(which is usually positive) and a negative ion. Hence, the names for metallic compounds are always in the following format: Name of metal + Name of negative ion However, do take note that for transition metals, the oxidation state has to be included. This is because transition metals have multiple oxidation states. The oxidation state of the metal is presented by: Metal (oxidation number). For example, rust is Iron (III) oxide. Cr2O3 is hence named chromium (III) oxide.
How ionic compounds named?
You need to indicate the charge of the cation when you are dealing with most transition metals or big metals like Pb or Bi. Unlike group 1 or group 2 elements, transition metals are typically capable of forming cations with many different charges. To give an extreme example, molybdenum can form cations with charges of +6, +5, +4, +3, and +2. So if someone were to say "molybdenum chloride", it could be any one of five compounds: MoCl2, MoCl3, MoCl4, MoCl5, MoCl6 To differentiate them you need to indicate the charge of the molybdenum: Molybdenum (II) chloride = MoCl2 Molybdenum (III) chloride = MoCl3 Molybdenum (IV) chloride = MoCl4 Molybdenum (V) chloride = MoCl5 Molybdenum (VI) chloride = MoCl6
How did alkaline earth metals get their names?
Alkaline earth metals were named "earth" to differentiate them from alkali metals, which were known to form alkaline solutions when reacting with water. The term "alkaline" was added to indicate they were compounds with a high pH.
What is the element name for Ruthenia?
The element name for Ruthenium is RU, which has an atomic number of 44. It is a transition metal in the platinum group with a grayish-white appearance. Ruthenium is used in various industrial applications, such as in electronics, jewelry, and catalysis.
How are covalent compounds named?
Covalent compounds are named by first looking at how many atoms the first element in a molecule has. We'll use H2O as an example (although it is commonly known as water). Since the H contributes two atoms to the molecule it has the prefix di-. If it had one it would be mono-, three, tri-, etc. The second element also follows that same rule, however, the ending is changed as well. In the case of oxygen, the -ygen is taken off and replaced by -ide. Therefore, the molecule H2O is also known as dihydrogen oxide.
How are oxidation states of transition metals indicated in the names of metals compounds?
The oxidation state of a transition metal in a compound is indicated by a Roman numeral in parentheses after the metal's name. For example, in FeCl3, iron is in the +3 oxidation state, so the compound is named iron(III) chloride. The Roman numeral helps identify the charge on the transition metal ion.
Which family is named for their ability to form compounds with all metals?
Help pleaseThe nitrates I remember (?), as being the only group that could form mercurous compounds, in solution. [All other compounds were precipitates?]Mercury is dangerous, and a mercury spill kit should be available whenever liquid mercury is being handled. These are sulphur powder, charcoal, and zinc. But check.
When naming a transition metal ion that can hace more than one common ionic charge the numerical value of the charge is indicated by a?
Because transition metals can assume more than one charge, the transition metal ion is named by using a Roman numeral

What is another name for metalloid?
A roman numeral in parentheses follows the name of the metal... apex
What are the 5 named groups from the periodic table?
The five named groups from the periodic table are the alkali metals, alkaline earth metals, halogens, noble gases, and transition metals. Each group has unique properties and characteristics based on their electron configurations.
A synthetic element that is also a transition metal is named what?
A synthetic element that is also a transition metal is named "rutherfordium." It is element 104 on the periodic table and belongs to the transition metal group. Rutherfordium is produced in nuclear reactors by bombarding actinide elements with high-energy particles.
How are metals named an ionic compound Nonmetals Polyatomic ions?
Metals in ionic compounds are named by using the metal's elemental name followed by the nonmetal's name with an "-ide" ending (e.g. sodium chloride). Nonmetals in ionic compounds use the nonmetal's elemental name followed by the metal's name with an "-ide" ending (e.g. oxygen and magnesium make magnesium oxide). Polyatomic ions maintain their specific names in ionic compounds (e.g. sulfate, nitrate, carbonate).
What is a transition metal with 25 electrons and starts with an O?
The transition metal with 25 electrons that starts with an O is the element named "osmium" (Os). It belongs to the platinum group of metals and has a dense, bluish-white appearance. Osmium is commonly used as an alloying agent in the production of hard and durable materials.
When naming binary ionic compounds are the nonmetal is named first?
No, the metal is named first in binary ionic compounds. The name of the metal cation is followed by the name of the nonmetal anion, with the nonmetal's name ending in "-ide". For example, NaCl is named sodium chloride.
What must be use when writing the chemical name for a compound with a transition metal?
Many transition metals can have multiple different oxidation numbers. When writing out the chemical name, you need to specify the oxidation number with a roman numeral.For example, Copper (II) oxide would be this: CuOWhile Copper (I) oxide would be this: CuO2
How are nonmetals in ionic compounds named?
Nonmetals(anion) are written second after the metal(cation).
