In scientific terms, an element is anything that can be found on the Periodic Table of Elements (PTE). It is a pure substance, not mixed with anything else. Compounds are a combination of 2 or more elements. They cannot be found on the PTE.
a compound is a mixture of elements. that is the difference

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.
A compound is a combination of at least 2 different elements or ions, while Hydrogen is simply an element.
A mixture is a collection of various elements which have not ionically bonded. A compound is when those elements are heated up and join together. Mixture = Iron and Sulphur Compound = Iron Sulphate
It is a big difference between the properties of reactants and products; an element is not a compound.
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.
The greater the difference in electronegativities between the elements in a compound, the stronger the bond will be. In this case, NaCl has a greater difference in electronegativities between sodium (Na) and chlorine (Cl) compared to KCl, since chlorine is more electronegative than sodium. This makes the ionic bond in NaCl stronger than that in KCl.
A compound is formed from elements.
elements are that they are only made up of one type of atom and a compound is chemically bonded together with differents substances.
If a compound is composed of nonmetal elements, it is likely covalent. Covalent compounds share electrons between atoms to form bonds. In contrast, ionic compounds are formed when a metal transfers electrons to a nonmetal, resulting in the attraction between positive and negative ions. The greater the difference in electronegativity between the elements, the more likely the compound is ionic.
