There are various ways to obtain the identity of a variable. One can obtain the physical properties of the chemical such as the boiling point or the melting point depending on the state of the substance. Another method is to determine the refractive index of the substance since most substances have a standard value.
The best way to determine the identity of a substance is to use spectroscopy. Infrared (IR) spectroscopy is commonly used to determine the functional groups present. Nuclear magnetic resonance (NMR)spectroscopy can tell you about the connectivity and spatial layout of the substance. Mass Spectrometry (MS) is used to determine what atoms and/or groups are present within a chemical. Ultra-violet visible (UV-Vis) spectroscopy can tell you about the pi systems of the molecules. In an undergraduate laboratory, these techniques are very common. However, there are many other forms including X-ray diffraction, atomic force microscopy, electron microscopy, flame testing, and gas chromatography.
What else can I help you with?
What determines an atom's identity and atomic number?
The number of protons.
What is the one thing that determines the identity of an atom?
the one thing that gives an atom its identity is the mass number and the atomic number
What is the one thing that determines the identity of an atom that is whether it is an oxygen atom or a carbon atom?
The number of protons in the nucleus of an atom determines its identity as a particular element. The number of protons is the element's atomic number, and is unique to each element. For example, the atomic number of oxygen is 8, while the atomic number of carbon is 6.
What subatomic particles gives an atom its identity?
Protons are the subatomic particles that give an atom its identity. The number of protons in the nucleus determines the element's atomic number, which in turn defines the specific type of atom.
What determent's an atoms identity?
An atom's identity is determined by the number of protons in its nucleus, which is called its atomic number. This number determines the element to which the atom belongs. Electrons can be gained or lost to form ions, but as long as the number of protons remains the same, the atom's identity remains unchanged.

What does the number of proton in an atom determine?
The number of protons in the nucleus of an atom determines the identity of the element.
What is the one thing that determines the identity of an atom that is whether it is an oxygen atom or a carbon atom?

Does the number of protons in one atom of an element determines the atoms?
Yes, the number of protons in an atom of an element determines the element's identity. It determines the element's atomic number, which is unique for each element.
What subatomic particles gives an atom its identity?
Protons are the subatomic particles that give an atom its identity. The number of protons in the nucleus determines the element's atomic number, which in turn defines the specific type of atom.
What determent's an atoms identity?

Electrons can be gained or lost to form ions, but as long as the number of protons remains the same, the atom's identity remains unchanged.
Does an atom retain the chemical identity of an element?
An isotope is an atom that contains a different number of neutrons. In order for an element to change there has to be a different number of protons.
What subatomic particle number determines the identity of an element?
The number of protons, which is the atomic number of an element, determines the identity of an element.
What represents the sum of proton in the nucleus of an atom?
The sum of protons in the nucleus of an atom is called the atomic number. It determines the element's identity.
