What is the meaning of determination of formula unit of compound?
It is the sum of atomic masses of all the elements in a given compound.
Is a methane an element or a compound?
Compound. Chemical formula: CH4, meaning it's 1 carbon atom and 4 hydrogen atoms.
Which element changes to gas state from solid state on heating?
ICE Ice is not an element, but iodine is. It will sublime - meaning it will go from a solid state to a gaseous state. Another common example is a compound, dry ice, which is solid carbon dioxide. Under the proper conditions, most elements will sublime. Consult the phase diagram for a given element to find out the conditions required.
What kind of matter is formed when atoms or two or more elements bond?
If three or more elements are bonded together in a compound (Eg. H2SO4) then that compound is called a "Polyatomic" ion. "Poly" meaning three or more. If there are only two atoms, it is Diatomic (Di meaning two). An example of a diatomic molecule would be CO2.
Is gold an example of an atom?
A single atom of any element can not be a molecule in the strictest sense, because a molecule must contain at least one chemical bond. (This does not mean that a single atom of gas can not be a kinetic-molecular theory unit, as is true for the noble gases.) A single atom of any element also can not be a compound because that by definition must contain at least two distinct elements.
Is ethyl alcohol an element?
No, it isn't. It is an organic compound of formula CH3CH2OH meaning it composes of 3 different elements.
When you have a pure substance how can you tell if it's a chemical or compound?
NMRI scan Properly phrased, it is either an element(meaning it is made up of only one element chemically) or it is a compound that is an amalgm of multiple elements.
What distinguishes a compound from an element?
An element consists of only one type of atom e.g. gold contains only gold atoms. A compound is two or more elements chemically combined eg. Carbon Dioxide, CO2, which contains one Carbon atom and two Oxygen atoms.
How do element differ than compound?
meaning of compound : combinations of two or more elements Compound (enclosure), a cluster of buildings having a shared purpose, usually inside a fence or wall Compound (fortification), a version of the above fortified with defensive structures Compound bow, a type of bow for archery Compound (linguistics), a word that consists of more than one radical element Compound (migrant labour), a hostel for migrant workers such as those historically connected with mines in South Africa Compound (music), an attribute of an interval or time signature Compounding, the mixing of drugs in pharmacy Polyhedral compound, a polyhedron composed of multiple polyhedra sharing the same centre element 1. elements The basic assumptions or principles of a subject. Chemical element, a building block in chemistry Electrical element, an abstract part of a circuit Heating element, a device that generates heat by electrical resistance Weather, sometimes referred to as "the elements"
What elements make copper?
copper is an element meaning it is pure. it has 29 elecrons, 29 protons, and 34.5 neutrons.
What elements can be combined with the element neon?
Neon does not naturally combine with any other element, as it is inert, meaning it iscompletely non-reactive under natural conditions. It has, however been observed to form a polyatomic ion with other gases (meaning that it combines with an element such as helium, argon or hydrogen) under extreme temperatures and pressures in a laboratory.
What is a pure substants?
A pure substance is any substance with a fixed chemical composition, meaning either a single element or a compound (chemically-bound elements in a fixed ratio).
How is pure element different from an element in compound?
A pure element (on an atomic scale) is a series of the same atoms (same amount of electrons). Elements in compounds are fused to each other meaning that their amount of electrons may have changed and they may have a different charge.

Is o3 compound or element atom or molecule compound or element or mixture or substance?
Yes....it is an element....it is an isotope...(isotope) meaning two or more forms of the same element whose atoms differ in number of neutrons... hence in mass. Example C - Carbon = Coal = Diamond -- diamond is the purest form of carbon
Are crystals broken down a compound or an element?
Compound, crystal is not an element so obviously what it is made up of must be a compound <><><><> Crystals can be either an element (diamonds are carbon- and crystalline) or a compound (salt, sugar). Unsure of your meaning of "broken down".
What is the meaning of determination of formula unit of compound?
It is the sum of atomic masses of all the elements in a given compound.
