How do you assign point group?
To assign a point group to a molecule, you first identify its symmetry elements such as rotation axes, mirror planes, and inversion centers. Then, use those elements to determine the point group using crystallographic tables or software. The resulting point group describes the overall symmetry of the molecule.
Which element has a higher melting point potassium in group 1A for calcium in group 1B?
Calcium, which is in Group 2 (not 1B, as there is no Group 1B), has a higher melting point than potassium, which is in Group 1. This is due to calcium being a metal with a higher atomic number and stronger metallic bonds compared to potassium, resulting in a higher melting point. Calcium's melting point is approximately 842°C, while potassium's is around 63.5°C.
What is the point group of dimethylbenzene?
Dimethylbenzene, commonly known as xylene, has several isomers, including ortho, meta, and para xylene. The point group of ortho-xylene is (D_{2h}), while meta-xylene belongs to the (C_{2v}) point group, and para-xylene is classified as (D_{2h}). The specific point group depends on the arrangement of the methyl groups on the benzene ring, affecting the symmetry elements present.
How melting and boiling point varied in a period?
Generally melting point and boiling point increase up to group 6 and then decrease.
What element has the highest melting point of its group?
The element with the highest melting point in its group is carbon. Specifically, graphite has the highest melting point among the carbon allotropes, which is higher than the melting points of other elements in its group.

What is point group of symmetry?
A point group of symmetry is a set of symmetry operations that leave at least one point unchanged in a molecular or geometrical structure. These operations include rotations, reflections, and inversions that can be applied without altering the overall shape of the object. Point groups are classified based on their symmetry elements, such as axes of rotation and mirror planes, and are essential in understanding molecular symmetry and its implications for physical and chemical properties. Common examples include the cyclic groups (Cn) and the dihedral groups (Dn).
DN 150mm dia casing pipe DN stands for?
DN stands for diameter nominal !! it has been taken from some language which say diamteree nominelle
What are the symbols of permutation groups?
some examples of symbols for permuation groups are: Sn Cn An These are the symmetric group, the cyclic group and the alternating group of order n. (Alternating group is order n!/2, n>2) One other is the Dihedral group Dn of order 2n.

DN 50 valve size?
DN 50 means: "DN": Diametre nominel - Nominal diameter of the valve, and "50" is the size of the valve in [mm]. Alternative is NPS (Nominal pipe size in inches).
