It has been found by mass spectrometric analysis that in nature, the relative abundances of the various isotopic atoms of silico

pochemuha

Answer:

This means that the isotope of silicon with a mass number of 28 is by far the most common of these three isotopes.

Explanation:

The abundance of Si-28 is 92.23%. Si-29 is 4.68% and Si-30 is 3.09%.

Because most Si atoms have a mass of 28 amu, the average mass of all silicon atoms is very close to 28.

Here is a video which summarizes how to calculate average atomic mass from data about mass and relative abundance.

Determine the hybrid orbital of this molecule.

Pavel [41]

The hybrid orbital of this molecule is $sp^3$ . Hence, option C is correct.

<h3>What is hybridisation?</h3>

Hybridization is defined as the concept of mixing two atomic orbitals to give rise to a new type of hybridized orbitals.

In this compound, $sp^3$ a hybrid orbital makes I-O bonds. Due to $sp^3$ hybridization iodate should have tetrahedral geometry but because of the presence of lone pair of electrons the shape of $IO^{3-}$ the ion is pyramidal.
