How can you tell the difference between an element and a compound

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. Examples of elements include iron, copper, hydrogen and oxygen. Examples of compounds include water (H2O) and salt (Sodium Chloride - NaCl)

Explanation:

Further Differences:

Defintion:

Compound - A compound contains atoms of different elements chemically combined together in a fixed ratio.

Element - An element is a pure chemical substance made of same type of atom.

Representation:

Compound - A compound is represented using its chemical formula that represents the symbols of its constituent elements and the number of atoms of each element in one molecule of the compound.

Element - An element is represented using symbols.

Composition:

Compound - Compounds contain different elements in a fixed ratio arranged in a defined manner through chemical bonds. They contain only one type of molecule. Elements that compose the compound are chemically combined.

Element - Elements contain only one type of atom. Each atom has the same atomic number i.e., the same number of protons in their nucleus.

conduction is the transfer of thermal energy (heat in transfer) due to collisions between the molecules in the object. collisions between adjacent atoms and molecules transfer kinetic energy from the warmer to the cooler object. the objects must be in physical contact.
