It is generally envisioned that the atom consisting of a dense, small nuclues is made up of spherical protons and neutrons, yet this nucleus is surrounded by electrons constantly in rapid motion, orbiting the nucleus so frequently that it often covers a larger sphere around it. However, since the electrons are constantly moving, they hold no actual shape, so we call this area in which the electron orbits the nucleus the Electron Cloud. For modeling purposes, an atom is often displayed as a simple sphere with no complexions, but no one knows for sure exactly what these atoms look like upclose.
linear
Trigonal Pyramidal. It is not trigonal planar because there is one lone pair around the central atom, just like the shape of ammonia.
That would be Trigonal Pyramidal in shape and have an sp3 hybridization.
A central atom attached to 3 other atoms, all lying on the same plane.
Trigonal pyramidal
angles
If you mean it by its atomic shape, its a hydrogen atom at both sides and an oxygen atom in the middle. But if you mean it by its normal appearance, then it can take up any shape.
All atoms are a fuzzy, indistinct shape.
It depends on the hybridization of the central atom.
Shapes of atoms are often undefinable.
A PH3 molecule has a triangular pyramidal shape. The central atom is the Phosphorus atom, which is connected to three Hydrogen atoms.
Origin
Origin
In an electric current.
It has 4 bonding pairs and no lone pairs so it has a tetrahedral shape.
The OsbCl3 ion has a tetrahedral molecular shape
the geometry of the central atom is trigonal pyramid and the shape of the compound will be bent
