Do ionic compounds consist of cations and anions present in a constant ratio?
yes
Why must the net charge on any ionic compound always equal zero?
They have no charge..the ions are attracted to opposite charge until the overall charge is zero
Do compounds always contain the same elements in the ratio?
Yes because no samples are exactly the same.
Is KNO3 ionic or covalent?
Potassium nitrate is ionic. Metal compounds tend to be ionic as metal atoms readily form positive ions. It consists of potassium (K+) ions (group 1 metals always form 1+ ions) and nitrate (NO3-) ions in a 1:1 ratio.
What is substance containing two or more elements chemically combined in a fixed ratio?
It is called a compound
Do all ionic compounds have the same ratio of ions?
No. The ratio depends on the charges of the ions.
What type of matter is made of elements in a specific ratio that is always the same?
Elements combined in specific ratios form compounds.
Why are prefixes not needed in the naming ionic compounds?
Ionic compounds do not contain discrete molecules but rather a repeating pattern of positive and negative ions in a crystal lattice. The charges on the ions already indicate the ratio of the elements present, so prefixes are not needed to specify the number of atoms like in covalent compounds.
Do ionic compounds consist of cations and anions present in a constant ratio?
yes
What is a substance containing two or more elements in a fixed ratio?
Two or more elements chemically combined is called a chemical compound. Compounds can be held together different interactions like ionic bonds or covalent bonds.
Which type of substance is composed of two or more different kinds of elements always in the same ratio?
Two or more different elements that are chemically combined in a definite ratio is a compound. Based on the nature of the bonds, it can be called an ionic compound (i.e. atoms bonded together by ionic bonds) or an molecular compound (i.e. atoms bonded together by covalent bonds).

They have no charge..the ions are attracted to opposite charge until the overall charge is zero

How do elements join to from compounds?
YES!!!! Taking Sodium and Chlorine as an example. Sodium metal is an element. Chlorine gas is an element. Put them together in a gas jar and they will react to form the compound sodium chloride. In nature atmospheric nitrogen (an element) will react with atmospheric oxygen (also an element), when a lightning strike discharges, to form nitrogen oxides (compounds).
What is the meaning of empirical formula?
Simplest atomic ratio of the elements present in the compounds.
