A molecule is the smallest particle of a substance that exists independently. Molecules of most elements are made up of only one of atom of that element. Oxygen, along with nitrogen, hydrogen, and chlorine are made up of two atoms. ... A compound is a substance formed when two or more elements are chemically joined.
(Hope that helps)
an element is a pure substance that cannot be broken down by any chemical means. for example: oxygen, hydrogen, etc
compound is a chemical species formed when two or more atoms join together chemically. for example: sodium chloride, calcium carbonate, etc
An element is either just one atom or a combination of the same atom. If they have the same amount of protons, they are the same element.
A compound is a thing that is composed of two or more different atoms.
A mixture is the material that is made out of two or more different elements/compounds (normally mixed together hence the name).
A solution is the outcome of the mixture, therefore a solution falls into the category of a mixture
The difference between an element and a compound is that an element is a substance made of same type of atoms , whereas a compound is made of different elements in definite proportions . Mixtures contain different elements and compounds but the ratio is not fixed nor are they combined via chemical bonds.
If you change the number of neutrons an atom has, you make an isotope of that element. All known elements are arranged on a chart called the Periodic Table of Elements. A compound is a substance made from two or more different elements that have been chemically joined.
These different versions of hydrogen are called isotopes. All isotopes of a particular element have the same number of protons, but can have different numbers of neutrons. ... A compound is a substance made from two or more different elements that have been chemically joined.
When the electronegativity difference is greater than 2.0, the bond is considered ionic.
Electronegativity (χ) is a property that describes the tendency of an atom to attract a shared pair of electrons. Atoms with higher electronegativity attracts more electrons towards it, electrons are closer to that atom. For example fluorine has electronegativity approximately χ = 4 and sodium χ = 1, fluorine attracts electron and it has negative charge and sodium has positive charge.
