Based on silicon's position on the periodic table, it has a. 14 electrons, which include 4 valence electrons in the third energy level and 10 electrons distributed over the first two energy levels. b. 14 electrons, which include 2 valence electrons in the third energy level and 12 electrons distributed over the first two energy levels. c. 14 valence electrons distributed over three energy levels. d. 14 electrons, which include 10 valence electrons in the second energy level and 4 electrons in the first energy level.

A. 14 electrons, which include 4 valence electrons in the third energy level and 10 electrons distributed over the first two energy levels.

Explanation:

Silicon is an element with atomic number 14 and thus contain 14 electrons. It is a p block element as the last electron enters the p orbital. The nearest noble gas is neon with 10 electrons.

The electrons are filled according to Afbau's rule in order of increasing energies and thus the electronic configuration in terms of noble gs configuration is:  

The valence electrons are the electrons present in last shell i.e n= 3, thus there are 4 valence electrons, 8 electrons in n= 2 and 2 electrons in  n= 1 energy level. Thus total of 10 electrons in first two energy levels.

a rain shadow is a dry region of land on the side that is protected against the prevailing winds of a mountain range. the prevailing winds are the winds that occur most of the time in a particular place of the earth

prevailing winds carry air toward the mountain range. as the air rises up over a mountain range, the air cools, water vapor condenses, and clouds form. on this side of the mountains, called the windward side, precipitation falls in the form of  rain  or snow. this dry air produces a  rain shadow.
