When determining the shape of a molecule, it is important to draw a lewis dot structure first in order to see the total number of answers?

Answer : The correct answer is, Valence electrons.

Explanation:

Lewis-dot structure : It is also known as electron-dot structure. It shows the bonding between the atoms of a molecule. it also shows the unpaired electrons present in the molecule.

When we are determining the shape of a molecule then it is important to draw a Lewis-dot structure and for drawing a Lewis-dot structure we should know that how many total number of valance electrons present in a given compound or a molecule.

For example :

The given molecule is,

As we know that tellurium has '6' valence electrons and chlorine has '7' valence electron.

Therefore, the total number of valence electrons in = 6 + 4(7) = 34

In , one-one electron of 4 chlorine combine with 4 electrons of tellurium and 2 pair electrons of tellurium left as a lone pair. That means, it has 4 bonding pairs and 1 lone pairs. So, the hybridization will be,

a galvanic cell( aka voltaic cell) and electrolytic cell

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).
