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
Where did the element chlorine get its name?
In 1810, Sir Humphry Davy discovered that Chlorine was an element, not a compound as was first thought. He named Chlorine after the Greek word χλωρος (chlōros), meaning green-yellow (the colour of Chlorine).
Which compounds are typically made from metal and a nonmetal?
A salt is a compound of a metal and a nonmetal. It's a slam dunk to see how this works if you pull out a periodic table and look at it. Grab any element from Group 1 (the so-called alkali metals) or Group 2 (the so-called alkaline earth metals) with any element from Group 17 (the so-called halogens) and you have a salt.The Group 1 and Group 2 elements are metals, and the Group 17 elements are non-metals. Note also that the Group 1 elements and Group 17 elements combine in a one-to-one ratio (like table salt - NaCl), and the Group 2 elements and Group 17 elements combine in a one-to-two ratio (like magnesium fluoride - MgF2).Certainly these aren't the only examples of the combination of a metal and nonmetal to form a compound, but they go a long way to answer the question. As to the chemistry of all of this, it's a piece of cake. And you can handle these ideas with just a bit of work.Wikipedia has a great periodic table posted, and it's interactive. Each of the elements listed on the chart is a link to the post on that element. Wow, what a time saver! Oh, and a link to that periodic table can be found below.
Why are there no compounds named cyclomethane or cycloethane?
Because you can't make a closed shape with <2 lines.

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 element is a transition metal that is found in period 5?
The elements in Period 5 that are transition metals are in Groups 3-12, including the Lanthanides and Actinides.
A synthetic element that is also a transition metal is named what?
Americium.
What are the 5 named groups from the periodic table?
Alkali Metals Alkaline Earth Metals Transition Metals / Metalloids (d group) Halogens Noble Gases
What must be use when writing the chemical name for a compound with a transition metal?
When writing the chemical name for a compound with a transition metal, it is important to include the name of the transition metal as well as its oxidation state in Roman numerals. This helps to specify which ion of the transition metal is present in the compound. Additionally, any ligands or other elements in the compound should also be named and included in the chemical name.
What are the covalent compounds?
Covalent compounds share electronsCovalent compounds are neutralB.The compounds share electrons.C.The compounds show no charge.D.The compounds are named with Greek prefixes.
How are nonmetals in ionic compounds named?
Nonmetals(anion) are written second after the metal(cation).
What are non metals that react with metals called?
All the elements with more than 4 electrons in the valence shell,which are usually gaining electrons and are reduced in the chemical reactions are named "non-metal".This does not include elements in transition metal
If element number 109 is produced will it be a transition element explain?
Element 109 has been discovered and repeatedly generated. It has been named Meitnerium (Mt) and is part of the Cobalt series (which is in the transition metals).
How are families of the periodic table named?
The Periodic table can be divided into nine families of elements each having similar properties. The families include: Alkali metals Alkaline metals The Transition metals Other metals Metalloids Non-metals Noble gases Rare Earth
