Ionic compounds do not require the presence of a metal, for example ammonium chloride is ionic and does not contain a metallic element. What is true is that the majority of ionic compounds involve at least one metal.

Is NaBrO3 molecular or ionic?
If a compound contains at least one metal atom and at least one nonmetal atom, the compound is ionic. Na (Sodium) is a metal. Br (Bromine) is a nonmetal. Therefore, the compound NaBr is ionic.
Do IONIC COMPOUNDS need to be positively charged?
No they are not positively charged. Ionic bonds comprise of anions and cations.
Why do you need to balance the numbers in an ionic compound what does this do?
We need to balance the number in an ionic compound b/c Ionic Compounds must be Neutral which means that is No Charge=0
Is SrS a ionic of covalent bond?
No. This is an ionic bond. Look at the electronegativity Cl (3.0) - Sr (1.0) = 2.0; 0.0 to 0.4 is covalent, 0.4+ to 1.7 is polar-covalent and above 1.7 is ionic. You can also assume that a metal and non-metal will form an ionic bonds.
Why are ionic compounds insoluble in organic compounds?
It isn't strictly true, but generally ionic compounds are not highly soluble in organic solvents because ionic compounds need a highly polar solvent to dissolve well (such as water) and in general organic compounds are not as polar as water. Remember, like dissolves like. However, many ionic compounds are very soluble in a variety of organic solvents, just not as much as in water.
What is the difference between the composition of binary ionic and binary molecular compounds?
Binary molecular (covalent) compounds are named according to the number of atoms in the compound. Each number has it's own prefix.List of Prefixes:mono-di-tri-tetra-penta-hexa-hepta-octa-nona-deca-For example:CO2 = Carbon dioxideBr2O7 = Dibromine heptoxide (note "a" is sometimes excluded for word flow)Br4Cl8 = Tetrabromine octachlorideIn comparison, ionic compounds don't have prefixes but the anion (second ion) always has the suffix "-ide"For example:Li2O- Lithium oxideCaBr2- Calcium bromideAl2O3- Aluminum oxideThe reason you don't need prefixes to specify the number of ions in an ionic compound is because the charges of the two atoms add to zero (you could figure it out if you wanted to based on the given information).
Why do ionic crystals have high melting points and high boiling points?
This is because of the strong force of attraction between the positively and negatively charged ions in the ionic lattice
Do Ionic compounds use prefixes mono di tri?
yeah.. mono-1 di-2 tri-3 tetra-4 penta-5 hexa-6 hepta-7 octa-8 nona-9 deca-10 dodeca-20 The real answer is NO. The prefixes are only used in Type III compounds which are Covalent Bonds. Ionic Bonds only need the ending -ide.
Why do scientist need to identify ionic compounds?
Because Ionic bonds are the strongest of all in chemistry. If a compound is ionic, it is unstable and will most likely fix itself with a corresponding ionic compound.
Why are ionic compounds usually have high melting point while most simple covalent compounds have low melting point?
Ionic compounds are mad by ionic bonding The two parts of the compound ther for become one by means of moving electronioc and beoming stable there fore the bond and the compound is stronger that conalent compounds which just share the electrons needed for the two (or more ) elements to become a compound so they are weaker
What 2 element types form an ionic compound?
A metal (as positively charged cations) and a non-metal (as negatively charged anions) need to be held together to form an ionic compound.
Do organic compounds have strong odors?
No. Ionic compounds do not have a smell. Ionic compounds are solid, for smells to diffuse through the air they need to be gases. Ionic compounds are solids and its particles are held too tightly, therefore they cannot release into the air and make the smell.
