Compound versus Element comparison chart

CompoundElement

DefinitionA compound contains atoms of different elements chemically combined together in a fixed ratio.An element is a pure chemical substance made of same type of atom.

RepresentationA 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.An element is represented using symbols.

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

ExamplesWater (H2O), Sodium chloride (NaCl), Sodium bicarbonate (NaHCO3) etc.Hydrogen (H), Oxygen (O), Sodium (Na), Chlorine (Cl), Carbon (C), Iron (Fe), copper (Cu), silver (Ag), gold (Au) etc.

Ability to break downA compound can be separated into simpler substances by chemical methods/reactions.Elements cannot be broken down into simpler substances by chemical reactions.

TypesA huge, virtually limitless, number of chemical compounds can be created. Compounds are classified into molecular compounds, ionic compounds, intermetallic compounds and complexes.There are about 117 elements that have been observed. Can be classified as metal, non-metal or metalloid.

Answer from: Quest

If a hydrogen atom is neutral, it must also have one electron. an oxygen atom (o) has an atomic number of eight (8). this means a neutral oxygen atom has eight protons and eight electrons. the element actium (ac) has an atomic number of 89, so it has 89 protons and 89 electrons in a neutral atom

Answer from: Quest

1. a)c-14 has two more protons

2. d)they have different numbers of protons, neutrons, and valence electrons; they are all gases at room temperature.

3. c) iron and nickel.
