Atomicity is having atoms. Also the number of atoms in a molecule.
That is by definition.
This is the definition of an "isotope".
The atomic number for any isotope of fluorine is always 9; that is the "definition" of fluorine.
the answer is the atomic mass unit
energy derived from the atomic nucleus
12 by definition.
Identically the same, by definition.
Atomic Mass Units.atomic mass unit
it is the branch of physics that deals with the structure and the behaviour of an atom is called atomic physics
Zirconium is the name of a chemical element. Zirconium has atomic number 40, which by definition means that is has forty protons in its atomic nucleus.
AMU stands for atomic mass units; the number of units an element has is called its atomic mass. The atomic mass of carbon is exactly 12, by definition.
An atomic fingerprint refers to a unique pattern of peaks in an atomic spectrum that corresponds to the energy levels of electrons in an atom. It is used to identify elements in a sample based on the wavelengths of light they emit or absorb.
