Select the electron domain geometry that results in a bent molecular shape. check all of the boxes that apply. linear with two atoms and zero lone pairs trigonal planar with three atoms and zero lone pairs trigonal planar with two atoms and one lone pair tetrahedral with three atoms and one lone pair tetrahedral with two atoms and two lone pairs

The correct answers are as follows:

The electron domain geometry that results in a bent molecular shape:

trigonal planar with two atoms and one lone pair

tetrahedral with two atoms and two lone pairs

The bent shape is the molecular geometry. The repulsion between the lone pair and bond pair electrons causes the molecule to have a bent shape.

Both the molecular and electron domain geometry is according to the VSEPR theory, wherein the number of electron pairs surrounding the central atom of a molecule determines its geometry.

most historians agree that gabriel mouton, the vicar of st. paul’s church in lyons, france, is the “founding father” of the metric system. he proposed a decimal system of measurement in 1670. mouton based it on the length of one minute of arc of a great circle of the earth (now called a nautical mile, 1852 meters). he also proposed the swing-length of a pendulum with a frequency of one beat per second as the unit of length (about 25 cm). a pendulum beating with this length would have been fairly easy to produce, thus facilitating the widespread distribution of uniform standards. over the years, his work was revised, improved, and extended by a number of french scientists.

the political sponsor of weights and measures reform in the french revolutionary national assembly was the bishop of autun, better known as talleyrand. under his auspices, the french academy appointed several committees to carry out the work of developing a usable system of weights and measures for france. one of the committees recommended a decimalized measurement system based upon a length equal to one ten-millionth of the length of a quadrant of the earth’s meridian (i.e., one ten-millionth of the distance between the equator and the north pole).
