Is copper still an element when it reacts with oxygen?
Yes, copper is still an element when it reacts with oxygen. The reaction forms copper oxide, but the copper atoms remain unchanged.
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 smallest particle of an element that still has the same chemical properties?
The smallest particle of matter that keeps all the same properties of oxygen is an oxygen atom. If you mean oxygen gas, O2, then it would be a molecule of two oxygen atoms covalently bonded.
What causes pennies to discolor?
Exposure to oxygen in the air and to dirt and oils from contact with skin. US cents have been made of copper-plated zinc since 1982, and before that most of them were bronze containing 95% copper. In either case the copper combines with O2 to cause discoloration. If undisturbed the coins can develop a greenish patina like the Statue of Liberty, which is made of copper. In general pennies are used enough that the patina can't develop but they still darken in color.
Is sodium the most abundant element in the ocean?
No, it is the most common dissolved ion in the ocean. The most common element by mass is oxygen as the ocean is still mostly water.
Is copper still an element when it reacts with oxygen?
Yes, copper is still an element when it reacts with oxygen. The reaction forms copper oxide, but the copper atoms remain unchanged.
How many atoms are there in a copper and what are they?
Copper is an element. You can have a single atom or many atoms and it's still copper.
Are 2 moles of oxygen still an element?
Yes, of course.
What is the smallest particle of matter which retains the identity of the element it comes from i?
An atom. In a sample of copper, for instance, the smallest unit of copper that is still considered copper is a single atom of copper.

A catchy slogan for the element lithium?
Even though it reacts with water, And reacts with your brain. Chemistry still sucks, And Lithium is to blame!
What is the smallest unit of a element that still maintains the characteristics of the element?
The smallest unit of an element that still maintains its chemical properties is an atom. Each element is uniquely defined by the number of protons in its nucleus, which stays constant in all atoms of that element.
Why do candles need oxygen?
YES. The available amount of oxygen in air regulates the candles burn. The oxygen burns with the paraffin wax. Both are consumed. A mix of more oxygen will burn faster and hotter. Rapid oxydation is dangerous.
Is melted copper a mineral why or why not?
Melted copper is not a mineral because minerals are naturally occurring inorganic substances with a specific chemical composition and atomic structure. Melted copper is a liquid form of the element copper, which is a mineral when in its solid state.
Is oxygen found in people?
Yes, especially in people who are still breathing, in which the element oxygen can be found in the lungs. Most of the oxygen in a living person or a corpse, however, occurs in compounds such as sugars and fats.
What would the interstellar word for oxygen be?
The interplanetary, interstellar, and even intergalactic word for oxygen would still be "oxygen".
