Air is mixture of at least four gasses. Each gas retains its owns distinct properties.
A protein can not be an element, because every protein must contain at least four elements: carbon, hydrogen, oxygen, and nitrogen. A pure protein is a compound, but it may be mixed either homogeneously or heterogeneously with other molecules that are so chemically similar that they are difficult to separate.
Four types of Heterogeneous mixtures are- Cake mix, This is known as a Mechanical Mixture. Rubbing Alcohol, This Mixture is an example of a Solution. Mud, Is type of Mixture called a Suspension. Mayonnaise, Is an example of a Colloidal Mixture
A mixture There are four types of mixtures: Alloy - homogenous metalic solid Solution - homogenous mix of two or more substances (not all metals) Suspention - not evenly mixed and will separate if left alone Colloid - Sorry, I always forget what this one is

The four "elements" are now classed as four different things completely: we know that fire is just the release of energy through combustion, water is a compound of oxygen and hydrogen, earth is a complex mixture of nitrates, phosphates and other ions and salts, and air is a mixture of elemental gases.
Quite simply, a C172 has four seats and a 152 only has two.
