Definitions

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