An element is a substance made up of only one type of atom, while an ionic compound is a compound containing more than one type of atom: an anion and a cation.
Definitions:
Atoms are made up of a dense nucleus containing positively charged particles (protons) and neutrally charged particles (neutrons), with negatively charged particles (electrons) orbiting the nucleus in shells/orbits.
Elements are substances made of only one type of atom. Elements are differentiated from each other by the amount of protons that they contain. For example, oxygen is the only element with eight protons, and is not made of any other element.
Compounds are two or more different types of atoms chemically bonded together. For example, one carbon atom and two oxygen atoms bond together to form the compound CO2 (carbon dioxide).
Ions are elements with a stable valence (outer) shell/orbit. For example, the Periodic Table of the Elements will tell you that oxygen has six valence electrons (electrons in the valence shell). However, atoms with more than one shell are unstable with less than eight valence electrons. Since atoms react and bond with one another to become stable, oxygen could have two electrons transferred to it by an atom with two valence electrons (beryllium, for example). With eight electrons in its second (outer) shell, the oxygen atom would be stable.
Anions are negatively charged ions.
Cations are positively charged ions.

Which property is the best indicator that a compound may be ionic?
The large difference in electronegativity between the elements in the compound is the best indicator that a compound may be ionic. Ionic compounds typically form between elements with a large electronegativity difference, resulting in the transfer of electrons from one element to another.
What test is commonly used to determine if a compound is ionic or covalent?
The electronegativity difference between the elements in the compound is commonly used to determine if a compound is ionic or covalent. If the electronegativity difference is large (typically greater than 1.7), the compound is likely ionic; if the difference is small (around 0.5 or less), the compound is likely covalent.
Is KF a polar covalent bonds or non-polar covalent or ionic?
KCl is an ionic compound. The electronegativity of potassium (K) is approximately 0.82. The electronegativity of chlorine (Cl) is approximately 3.16. The difference between these electronegativities is 2.34. This high electronegativity difference is what makes potassium chloride an ionic compound. If the electronegativity difference of two elements is greater than 1.7, it is considered to be an ionic compound. If the difference is between 0.4 and 1.7, the compound is considered to be polar covalent. If the difference is less than 0.4, the compound is considered to be covalent. If the difference is 0 (i.e. the two elements are the same), then the compound is considered to be pure covalent. KCl is ionic because K's electronegativity is 0.82 and Cl's is 3.16. A compound is ionic when the electronegativity on the Pauling Scale is more than 2.1. The difference 2.34, so it is ionic.
Is iron III oxide a molecular compound why?
No. Iron III oxide is an ionic compound. This is due to the large difference in electronegativity between oxygen and iron. If the electronegativity difference is greater than 2.0 a compound is generally ionic. The difference between iron and oxygen is 2.61.
How do you calculate a compounds ionic character?
One common method for calculating a compound's ionic character is to determine the difference in electronegativity between the atoms involved. The greater the difference in electronegativity, the more ionic character the compound will have. Another way is to look at the compound's bond strength and the degree of electron sharing between the atoms; stronger bonds and less electron sharing indicate more ionic character.

Is iron(III) oxide a molecular compound or ionic?

IS Cr2O3 molecular or ionic compound?
It is ionic compound as the difference in the electronegativity between chromium and oxygen is more than 1.7
Is Iron (III) oxide molecular or ionic?
No. Iron III oxide is an ionic compound. This is due to the large difference in electronegativity between oxygen and iron. If the electronegativity difference is greater than 2.0 a compound is generally ionic. The difference between iron and oxygen is 2.61.

What would fluorine have to combine with to form an ionic compound?
If fluorine combines with an element such that their electronegativity difference is more than 1.7, then they will form an ionic compound. Example:- Hydrogen fluoride is an ionic compound. Hydrogen has electronegativity of 2.1 and fluorine has 4.0. So, the difference is 1.9. Therefore, it is an ionic compound.

Is a ionic compound likely to form between fluorine and chlorine why or why not?
No, they form a covalent compound because there is not a great enough difference in electronegativity for one element to completely pull the electrons away from the other.
Is CaS a covalent compound?
Ca (calcium) is an element, not a compound. and it can only form ionic compounds.
Is iron a ionic compound or covalent compound?
Iron is not a compound, it is a metallic element.
