Why copper is a element?
Copper is an element because it is the simplest form of the substance that still makes it copper. It cannot be broken down into simpler substances through chemical means. Copper has atomic number 29.
What is the pure substance that cannot be broken down into simpler substances by ordinary chemical means?
An element is a pure substance that cannot be separated into simpler substances by physical or chemical means. Atoms are the smallest particles in which an element can be divided and still retain its properties.
Can metal elements be broken down by physical or chemical methods?
Elements are substances that cannot be broken down into any simpler substances. Hence they cannot be broken down by chemical methods. They may change in appearance if physical methods, but chemically, they still remain as the element.
Is the smallest particle of a substance that is still that substance having all the properties of that substance?
If the substance is an element the answer is an atom. If the substance is a compound the answer is a molecule.
What does not describe a element?
To be an element, a substance must have all the same type of atom. So, any substance that has more than one type of atom in isn't an element. Examples of non-element:Sodium Chloride - 2 types of atomsCarbon Dioxide - 2 types of atomsGlucose - 3 types of atomsSulphuric Acid - 3 types of atoms

What is the smallest unit of an element that still retains the properties of that substance?
An atom of that element.

If the substance is an element the answer is an atom. If the substance is a compound the answer is a molecule.
Introduction about compound?
A compound is more that one element (an element is a single atom of a substance ie H hydrogen ) a compound is still considered to be a pure substance
Are broken pieces a chemical change?
No, it is a physical change as the identity of the substance remains the same. Broken glass is still glass.
What single feature defines the properties of a element?
If a single atom of a hunk of matter is still the same substance as the matter, then that matter is an element. (Gold, sodium, carbon, uranium, and so forth) If the matter can only be broken down to a molecule, but not an atom, then it is not an element. (Salt, ammonia, sugar, alcohol, and so forth)
What is the smallest particle of a substance that is still identifiable as that substance?
A molecule if it is a compound, an atom if it is an element and a formula unit if it is an ionic crystal.
The smallest part of a substance that still has the characteristics of that substance is a what?
The smallest part of a substance is a molecule. A molecule can be a compound of different elements or be comprised of a single element.
Why helium is an element?
Helium is an element because it contains only one atom in its simplest form.
If a chemically pure substance that cannot be broken down into smaller substances?
A chemically pure substance is a substance that cannot be separated expect by chemical means. For instance, water can be broken down by electrolysis into oxygen and hydrogen. Yet, it is still a pure substance because a chemical change must occur in order for this to happen.
