Only for easy understanding we imagine the shape of atom as spherical one. In reality electrons, protons and neutrons, all other subatomic particles are only in the form of fields. Hence shape is arbitrary.
Molecules, with only a few exceptions, are not spherical.
yes,sigma orbital are gerade as these orbitals are symetrical
In coordination chemistry, high spin complexes have unpaired electrons in their d orbitals and are typically larger in size, while low spin complexes have paired electrons in their d orbitals and are usually smaller in size. These differences affect the magnetic properties and colors of the complexes.
This is an odd question. Usually it is considered that the electrons transferred to an anion populate the lowest available orbitals, in the case of N3- these would be the 2p orbitals. In valence bond theory which is used to explain the bonding in covalent chemical compounds, atomic orbitals are hybridised so as to create new orbitals that point along bond axes.
this molecule has a similar shape to ammonia, however the bond angles are less- ammonia is 1070 whereas arsine is only 91 0. Usually it is said that the hybridisation in AsH3 is sp3 (however this would imply a bond angle of 109.5- which is close to the ammonia angle)- however the angle of 91 0 is so close to the angle between the p orbitals (900)that it suggest there is no hybridisation at all, and that the As- H bonds involve only p orbitals.
most metals do not follow the octet rule. when an atom has access to the D orbitals it usually follows the 18-electron rule (transition metals). non transition or F block elements usually contain a d orbital (when present) that is below the s and p orbitals in energy and do not usually use D electrons in bonding.
All electron shells form a spherical shape. The electromagnetic force is exerted in a spherically symmetrical manner, so it produces spherical results. For atoms other than hydrogen, which usually have more than one electron, the electrons do not have to fit together as concentric spheres; their individual orbitals can have all sorts of shapes, but those shapes add up to spherical shells, nonetheless.
Planets are approximately in shape, usually elongated spheres called spheroids (squashed spheres)
Today, butlers are usually portrayed as being refined and well-spoken.
Usually a sphere or a group of few spheres.

Usually a circle but its properties can also be applied to spheres
they are used as variables. usually as an identified number.
Religion is usually portrayed as negatively or positively depending on the area that you live in or that specific persons religious views
Electrons are usually found in the electron cloud surrounding the nucleus of an atom. The exact location of an electron within this cloud is described by its probability distribution, which is represented by atomic orbitals. Electrons can be found occupying specific energy levels or orbitals within an atom.
Because that is how the game is programmed: Collect blue spheres and avoid red spheres. This is probably not changed to avoid confusion, or simply because red is usually the colour of negativity.
Usually portrayed in a negative light.
