What else can I help you with?
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.
What is the sentence for element?
Science has discovered many Element. Some of those element are very important for us.
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.
The term biodegradable means that a substance is not dangerous true or false?
False. The term biodegradable refers to a substance's ability to be broken down by natural processes, such as microorganisms, into simpler, non-harmful compounds. However, a substance being biodegradable does not automatically mean it is not dangerous, as its breakdown products could still be harmful to the environment or living organisms.
What do you call matter that can't be physically Separated?
I believe that we call matter that can no longer be separated into unique parts an atom. You cannot get any smaller than an atom and still have a recognizable substance. We can separate molecules into individual atoms. Elements consist of the same type of atom (i.e. gold is an element because it consists entirely of the atoms with the same number of protons and neutrons).

What is the smallest unit of an element that still retains the properties of that substance?
An atom of that element.
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.
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.
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
Suppose you have a pure substance. How can you tell whether it is a compound or a element?
It is really easy to identify a mixture when it's a formula and if it's to different colored substances. In a formula a MIxture will be joined by a plus sign. WHen you are actually working with two substances look for the difference between the two take sulfur and Iron for example, you can see the little yellow speects, so you know right away that it is a mixture. A pure substance you can't just look at it a know it's compound or an element you have to find out if it's homogenous( you can only see one substance) or is it's Heterogenous( you can see more than one) these two you can just look at it and see if it's one or the other. Milk would be and example of homogeneous because you can only see the white nothing else. Sulfur and iron would be and example of heterogeneous because you can see more then one substance(even though Sulfur and Iron together form a mixture) In a elements case you need to look at the Formula it's in like Ne would be an element because it's only one substance. Also if it was Ne2 it still would be one but it's proper name would be a diatomic element but still considered an element.A compound can always be addentified by it's formula it will have to element together without a plus sign in between(remember that is a mixture.

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)
The smallest part of a substance that still has the characteristics of that substance is a what?
The smallest part of a substance that still has the characteristics of that substance is called a molecule.
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 do you call matter that can't be physically Separated?
I believe that we call matter that can no longer be separated into unique parts an atom. You cannot get any smaller than an atom and still have a recognizable substance. We can separate molecules into individual atoms.
