Answer by Taffybohl. Confidence votes 309. The correct term for referring to a group of cats is 'clowder.' Interestingly, there are also two other valid ways to refer to a group of cats, other than just saying group of cats or cats.. Those other two terms are 'clutter' and 'glaring.'.
Because the volume of each of the eight corner atoms is shared between eight adjacent cells, each BCC cell contains the equivalent volume of two atoms (one central and one on the corner). Each corner atom touches the center atom.
In each of those molecules or ions, the central atom and the four outer atoms are all in the same plane, with bond angles of 120Âº between the outer atoms. If a molecule has three outer atoms and ONE lone pair of electrons on the central atom, it is trigonal pyramidal.Some examples are NH3 (ammonia), ClO3^-1 (the chlorate ion), H3O^+1 (the hydronium ion), and PCl3 (phosphorus trichloride).est Answer: You can tell the difference by examining the Lewis structure. If a molecule has three outer atoms and NO lone pairs of electrons on the central atom, it is trigonal planar. Some examples are SO3 (sulfur trioxide), CO3^-2 (the carbonate ion), NO3^-1 (the nitrate ion), and BF3 (boron trifluoride).
