Is fei3 ionic?
A binary ionic compound is composed of ions of two different elements – one of which is a metal, and the other a nonmetal. For example, iron(III) iodide, FeI3, is composed of iron ions, Fe3+ (elemental iron is a metal), and iodide ions, I- (elemental iodine is a nonmetal). Rule 1.
What is the compound for fei3?

Is FeCl2 a Type 1 binary ionic compound?
Examples of type 1 binary ionic compounds are as FeCl2 and FeCl3, AgCl and AgCl2.
What are examples of binary ionic compounds?
Binary Ionic Compounds Containing a Metal and a Nonmetal.
| NaCl | Sodium chloride |
|---|---|
| AlBr3 | Aluminum bromide |
| Ca3P2 | Calcium phosphide |
| SrI2 | Strontium iodide |
| FeCl2 | Iron(II) chloride or ferrous chloride The cation charge must be specified since iron can form more than one charge. |

Does tin have multiple charges?
The symbol “Sn” corresponds to the element tin, which may have either a +2 or +4 charge in ionic compounds (for a list of oxidation states available to the elements, consult a periodic table or see here).
What is the oxidation number of FeI3?
3
The oxidation number of iron in iron triiodide is 3.
What are Type 1 binary ionic compounds?
Type I Binary Ionic Compounds. 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 are the 2 types of binary 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.
What is the difference between ionic compounds and binary ionic compounds?
The key difference between ionic and binary compounds is that ionic compounds contain two charged components whereas binary compounds contain two different chemical elements.
What metals can form multiple ions?
A few elements, all metals, can form more than one possible charge. For example, iron (Fe) atoms can form 2+ cations or 3+ cations. Cobalt (Co) is another element that can form more than one possible charged ion (2+ and 3+), while lead (Pb) can form 2+ or 4+ cations.
Why FeI3 do not exist?
Answer. I- is much larger in size, so has higher tendency to lose electron, and hence is a good reducing agent. I- reduces Fe3+ to Fe2+ and itself gets oxidised to I2, hence FeI3 is unstable.
Why is FeI3 unstable?
FeI3 is thermodynamically unstable because Fe+3 has strong oxidizing power but I- has very less reducing power. Hence Fe+3 cannot be reduced by I- and the compound FeI3 cannot be formed.
Does tin form more than one cation?
Metals that form more than one cation.
In such cases, the positive charge on the metal is indicated by a roman numeral in parentheses immediately following the name of the metal. Thus Cu + is copper(I) (read as “copper one”), Fe 2+ is iron(II), Fe 3+ is iron(III), Sn 2+ is tin(II), and Sn 4+ is tin(IV).
Which metals form more than one type of ion?
What is oxidation and reduction number?
Oxidation is an increase in oxidation number (loss of electrons); reduction is a decrease in oxidation number (gain of electrons).

How do you tell if a compound is type 1 or 2?
Type I Binary Ionic Compounds – Naming and Writing Formulas
How can you tell if an ionic compound is type 1 or 2?
Type I Compounds – The metal present forms only one type of cation. Type II Compounds – The metal present can form two or more cations with different charges.
How can you tell if a binary ionic compound is Type 1 or Type 2?
When naming these compounds, its composition must be considered. 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.
How do you determine if a compound is ionic or covalent?
If a compound is made from a metal and a non-metal, its bonding will be ionic. If a compound is made from two non-metals, its bonding will be covalent.
How do you identify ionic and covalent compounds?
As a general rule of thumb, compounds that involve a metal binding with either a non-metal or a semi-metal will display ionic bonding. Compounds that are composed of only non-metals or semi-metals with non-metals will display covalent bonding and will be classified as molecular compounds.
What group forms two ions?
1 Answer. The elements that are most likely to form 2− ions are the group 16 elements. Their atoms have 6 valence electrons, and need 2 more to have a full valence shell of 8 electrons in order to become stable. When they gain 2 electrons in order to have 8 valence electrons, an octet, they gain a 2− charge.
