Well, darling, the electron-pair geometry for As in AsO2- is trigonal pyramidal. Don't let the fancy terms scare you, it just means that the electron pairs around the As atom are arranged in a pyramid shape with one lone pair and three bonding pairs. So, As is strutting its stuff with a sassy pyramid vibe in this molecule.
Euclidean geometry, non euclidean geometry. Plane geometry. Three dimensional geometry to name but a few
There are different kinds of geometry including elementary geometry, Euclidean geometry, and Elliptic Geometry.

Plane Geometry and Solid Geometry
Geometry that is not on a plane, like spherical geometry
There are two lone pairs on the arsenic atom in ASO2.
The chemical name for AsO2 H2O is arsenous acid.
The electron pair geometry for SO3 is trigonal planar. This is because the sulfur atom is surrounded by three regions of electron density, leading to a molecular geometry with a symmetric, flat triangular shape.
Arsenic in AsO2 has one lone pair of electrons. This is because the arsenic atom has a steric number of 4, including 3 bonded atoms (two oxygen atoms and one other atom in the molecule) and 1 lone pair, following the octet rule.
Euclidean geometry has become closely connected with computational geometry, computer graphics, convex geometry, and some area of combinatorics. Topology and geometry The field of topology, which saw massive developement in the 20th century is a technical sense of transformation geometry. Geometry is used on many other fields of science, like Algebraic geometry. Types, methodologies, and terminologies of geometry: Absolute geometry Affine geometry Algebraic geometry Analytic geometry Archimedes' use of infinitesimals Birational geometry Complex geometry Combinatorial geometry Computational geometry Conformal geometry Constructive solid geometry Contact geometry Convex geometry Descriptive geometry Differential geometry Digital geometry Discrete geometry Distance geometry Elliptic geometry Enumerative geometry Epipolar geometry Euclidean geometry Finite geometry Geometry of numbers Hyperbolic geometry Information geometry Integral geometry Inversive geometry Inversive ring geometry Klein geometry Lie sphere geometry Non-Euclidean geometry Numerical geometry Ordered geometry Parabolic geometry Plane geometry Projective geometry Quantum geometry Riemannian geometry Ruppeiner geometry Spherical geometry Symplectic geometry Synthetic geometry Systolic geometry Taxicab geometry Toric geometry Transformation geometry Tropical geometry
This is the meta-arsenite ion. As a free discrete ion it probably does not exist. Unlike nitrite ion which is a symmetric bent molecule with two identical N-O bonds, with formally 1 double bond. In the solid phase the meta-arsenites such as NaAsO2 contain polymeric chain ions.
As,Arsenic belongs to nitrogen family in periodic table so it has 5 valence electrons.

Euclidean geometry, non euclidean geometry. Plane geometry. Three dimensional geometry to name but a few
There are different kinds of geometry including elementary geometry, Euclidean geometry, and Elliptic Geometry.
Fun geometry, specific geometry, monster geometry, egg geometry, trees, turtles.
One main characteristic of non-Euclidean geometry is hyperbolic geometry. The other is elliptic geometry. Non-Euclidean geometry is still closely related to Euclidean geometry.
