Is iodine crystals an element compound or mixture?
Iodine is a chemical element; not a mixture, not a compound.
Matter that is an element or a compound?
Matter that is an element consists of only one type of atom, such as oxygen or gold. Compounds consist of two or more different elements chemically bonded together, such as water (H2O) or carbon dioxide (CO2).
Is pure gold a compound?
No, it's pure gold. It is an element. However, most jewelry is a compound of gold and silver or other metals to make it harder and stronger.
What happens in a single-replacement reaction-?
One element takes the place of another in a compound.
What reaction shows one element taking the place of another in a compound?
A single-replacement reaction
Which minerals are oxides compound ls that consist of oxygen and one other element?
There are many thousands of such minerals.

A sample of an element consists of the same type of atom. What does a sample of a compound consist of?
Identical molecules.
What is a substance that is not a compound called?
A substance can be a mixture or solution, rather than a compound. These do not require that the separate substances combine chemically. An element is a substance that has only one type of atom.
Is hydrogen gas a compound?
NO!!!!! Hydrogen gas as represented in the Periodic Table has the symbol 'H'. As a gas it exists as the diatomic molecule (H2) (H - H) This is NOT a compound. A compound is a substance that consists of two or more different elements e.g. Water (H2O) or Carbon dioxide (CO2). NB A compound is a molecule However. NOT all molecules are compounds. e.g. A particle of water is a molecule and a compound. However, a particle of hydrogen is molecule , but NOT a compound.
What is a simple explanation of what a compound is?
All a compound is matter that consist of more than one type of element that are bonded together chemically. They must be different to be considered a compound ! They cannot be broken down by physical means. Ex.: H2O has two hydrogen atoms and one oxygen.
Is carbon a element or a compound or a homogeneous mixture or a heterogeneous mixture?
Compound it cant be an element because its a diatomic or polyatomic cnt remember which one but either way its not an element its a compound. Compound it cant be an element because its a diatomic or polyatomic cnt remember which one but either way its not an element its a compound.
Why is element and compound is different?
An element is composed of only one kind of atom. A compound is composed of atoms of more than one element.
Is pure gold a compound?
No, it's pure gold. It is an element. However, most jewelry is a compound of gold and silver or other metals to make it harder and stronger.
Is NaCl a element or compound?
Neither, as there is no such thing as NaC1. However, NaCl, eith a lowercase L is sodium chloride, a compound. Each symbol on the periodic table of elements represents an element and is either a capital letter by itself, like H, or a capital letter with a lower-case letter, like He. The molecules of a compound consist of more than one element, so the symbol of a compound will include more than one capital letter. A molecule can have more than one atom but still be an element as long as all of the atoms are of the same element. For example, ozone is a special form of the element oxygen; its symbol is O3.
What happens in a single-replacement reaction-?
One element takes the place of another in a compound.
