The ion for Potassium has a charge of 1+.
The ion for Iodine has a charge of 1-.
This means that in order to make the overall charge of a unit of a compound of Potassium and Iodine, there must be one atom of Potassium and one atom of Iodine.
Therefore, when K+ and I- are bonded, they make the ionic compound of KI.

What is the formula name for this ionic compound K plus PO43-?
The chemical formula K3PO4 is for tripotassium phosphate.
What are the smallest units of ionic compounds called?
Ionic compounds are made up of positively and negatively charged ions, which are the smallest units of these compounds. These ions are held together by strong electrostatic forces known as ionic bonds.
What is the formula of the ionic compounds formed from aluminum and Lithium?
The ionic compound formed from aluminum and lithium is lithium aluminum hydride (LiAlH4).
Which of the formulas ionic compounds is incorrect?
The formula for ionic compounds reflects the ratio of ions present. If the charges of the ions are not balanced and do not add up to zero, then the formula is incorrect. For example, Na2O2 has an incorrect formula because the charges of Na (sodium) and O (oxygen) do not balance out.
Do ionic compounds form hydrates?
Yes, ionic compounds can form hydrates by attracting and binding water molecules within their structure. This results in the formation of hydrated compounds with a specific number of water molecules associated with each formula unit of the ionic compound.
What is the ionic formula for compounds formed between K plus and N3?
K3n
What can be used to represent an ionic compound?
formula mass can be used for ionic compounds.
Why ionic compounds do not posses molecular formula?
it is not a molecule
What is the formula name for this ionic compound K plus PO43-?
The chemical formula K3PO4 is for tripotassium phosphate.
Which elements have compounds of the general formula XY?
Alkali metals (like Na and K) and halogens (like Cl and Br) have the general ionic formula format XY (X+ and Y- in solution)
What are the smallest units of ionic compounds called?
Ionic compounds are made up of positively and negatively charged ions, which are the smallest units of these compounds. These ions are held together by strong electrostatic forces known as ionic bonds.
Is H2O a formula unit?
No. It is a molecule. The term formula unit is generally reserved for ionic compounds.
What is the chemical formula for the ionic compounds of sodium and oxygen?
Na2O and Na2O2
What is the formula of the ionic compound?
The potassium ion (cation) is K+.
Is K2Cr2O7 a formula unit or molecules?
K2Cr2O7 is a formula unit because it represents the simplest whole-number ratio of ions in the compound potassium dichromate. Formula units are used for ionic compounds, while molecules are used for covalent compounds.
What is salts molecular?
For ionic compounds the correct term is formula unit, not molecule.
What is the relationship between a empirical formula and formula unit?
The empirical formula represents the simplest whole-number ratio of atoms in a compound, while the formula unit represents the combination of ions in an ionic compound. The empirical formula is used for covalent compounds, while the formula unit is used for ionic compounds.
