The properties from the original elements are all left behind; almost no compound shows any of the properties of its constituent elements (the most widely used example of this is sodium and chlorine forming sodium chloride).

Properties of matter and examples?
It's interesting that a lot of answers can be found through google, but I only answer the ones that are from my own experience. Matter exists at three states that are a function of temperature. Let's assume around 70 degrees. Gas, liquid or solid. Metal other than mercury will be solid. But the metal has other properties as to how easily it is bent, electric conductivity and weight (or density). Do they oxidize easily. Take iron and aluminum. Aluminum bends easily and is highly conductive, light, and does not oxidize easily. Iron on the other hand is less conductive, very hard and must be heated to a high temperature to bend, and it oxidizes (rust) easily. Of course Iron mixed with other metals (such as Tungsten or Chromium) can be made more "friendly" for whatever the need is. God is great for tooth crowns because it is non reactive in your mouth. That is it's not breaking down into other chemicals. Gases and liquids have different densities, reactivity with other elements, and electrical properties. Take for instance an inert gas like Neon, and a highly reactive gas like Neon. Liquids are similar, differing in density (or weight), electrical properties, stability or reactivity. Take water for instance, which can exist of course in all three states (solid, liquid and gas) at typically encountered temperatures. Water is stable, however does react with compounds or elements to form different compounds. Like water and the gas sulfur dioxide react to form sulfuric acid. Sea water varies in salinity and the more salt dissolved, the heavier the water. It's easier to swim in the highly dense salt water. Ice tends to hold positive charges while liquid water negative charges. This can result in lightning in thunderstorms.. For a person interested in more specifics about the elements, learn about the periodic table and what it tells you. For other more specific questions about compounds or elements I will always look in "The Handbook of Chemistry and Physics"
Are the physical and chemical properties of a compound necessarily similar to those of the elements from which it was composed?
No. Take sodium chloride. Sodium is a metal that's flammable in air, and chlorine is a gas. Put them together, and you get nice inert crystals that are safe to eat.
Most of the matter in the universe exists as?
Matter is made up of elements and compounds, which are made up of atoms. But in an atom, most of the volume that it takes up is empty space. So all matter is mostly made up of empty space.
Components of a mixture differ from the components of a pure substance?
The concentrations of the components of a mixture may vary. However, a pure substance has a definite composition that does not vary.
What proved that Mendeleev was right?
The validity of the periodic table of elements, which was originally devised by Mendeleev, has been confirmed by a vast body of chemical research. It would not be an exaggeration to say that everything in the science of chemistry conforms to Mendeleev's theory.
Are oxygen and hydrogen compounds or molecules?
Hydrogen and oxygen are elements that usually take the form of molecules.
Gold and silver are compounds or elements?
they are elements compounds are when you take two or more elements and mix them together.
How do the parts of an atom combine to form compounds and mixtures?
It's not the atoms that change, it is the molecules... In short, the molecules(elements) can share, give, or take electrons from other molecules(elements).
Do elements make compounds or do compounds make elements?
An element is the most broken down form of any substance. For example, if you could take a molecule of iron and look at it, that would be an element. A compound is made up of different elements. For example, if you could take a molecule of water and look at it, you would be looking at hydrogen and oxygen bonded together.
Can elements be created in the body?
No, it is impossible. It is impossible for elements (matter) to be created by a human. The only new elements that are formed are in the center of stars where atomic nuclei merge. The human body does, however, take many elements and form numerous compounds.
What form do ionic compounds take?
Giant lattices.
Are the properties of a compound the same as the elements that form it?
Not always. For example sodium (Na), a metal that reacts violently with water, and chlorine (Cl), a yellow poisonous gas, combine to make table salt, which has none of these properties. But in others cases there are some similarities, like in a metal alloy.
How would the world be different if elements did not combine to form elements?
If elements did not combine then life would not exist. The would be no compounds or mixtures of any kind. Chemical and nuclear reactions would not take place. All bodies in the universe could consist of a single type of element.
What is the smallest part of a chemical element that can be combined with other elements to form compounds?
An atom. However it should be noted that generally the valence electrons in an atom take part in a chemical reaction.
Why is air a matter?
Air consists of a variety of different gases in relative proportions. Air is composed of oxygen, nitrogen, carbon dioxide, methane, and other elements and compounds. These elements and compounds have a mass and they take up space. Matter is defined as anything that has mass and takes up space (matter has a mass and volume). Air is matter because it fits the definition of matter (based on its properties and how we currently think about matter).
Why are all the elements in a column called a family?
They all have similar chemical properties, take chemical properties to be physical traits and it much resembles a family
What are the properties of liqiuid?
Liquids have a set volume but take the form of the container they are in.
