Definitions
Atomic Number of Thulium: The atomic
number or the so-called proton number for any chemical element is the number of
protons present in the nucleus of each atom of that chemical element. The
atomic number uniquely identifies an element chemically. It corresponds to the
charge number of the nucleus.
Symbol of Thulium: A chemical element symbol is a
one- or two-letter abbreviation of the chemical element's name. And when a
symbol consists of two letters, the first letter is always uppercase, and the
second letter is lowercase.
Atomic Mass of Thulium: The atomic mass
of Chemical Victory is the mass of an atom. Although the SI unit of atomic mass
is the kilogram, atomic mass is often expressed in a non-SI unit dalton where
the mass of 1 dalton is defined as 1⁄12 of the mass of one carbon-12 atom in
sleep state.
Oxidation States of Thulium: Chemical state
The oxidation state, sometimes referred to as an oxidation number, describes
the degree of oxidation of an element's atom in a chemical compound.
Standard State of Thulium: In
chemistry, the standard state of a substance is a reference point that is used
to calculate its properties under various conditions. Whether it is liquid,
solid or gaseous.
Electron configuration of Thulium: In atomic
physics and quantum chemistry, electron configuration is the distribution of
the electrons of an atom or molecule into atomic or molecular orbitals.
