Definitions
Atomic Number of Protactinium: 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 Protactinium: 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 Protactinium: 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 Protactinium: 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 Protactinium: 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 Protactinium: In atomic
physics and quantum chemistry, electron configuration is the distribution of
the electrons of an atom or molecule into atomic or molecular orbitals.
