How many unpaired electrons are present in the ground state of the atoms in Group 4A(14)? unpaired electrons

4

Explanation:

The particular element is silicon with atomic number of 14

Its electronic configuration is 1s2 2s2 2p6 3s2 3p2.

Looking at it, the outermost p orbital has capacity of 6 electrons but because the outermost electron in the p orbital of this element is 2, therefore the unpaired electrons is 4 (6-2)

the correct answer is 2

i just did this assignment :)

the ozone layer acts as a filter for the shorter wavelength and highly hazardous ultraviolet radiation (uvr) from the sun, protecting life on earth from its potentially harmful effects. when the sky is clear, there is an inverse relationship between stratospheric ozone and solar uvr measured at the earth's surface.
