1s22s22p63s23p64s23d104p65s24d9 what is this element

Silver(Ag)

Explanation:

We could count the total number of electrons by looking at the electron configuration.

The count of the total number of electrons will tell us the Atomic Number.

From that we can tell what element it is.

To calculate Atomic Number we see the configuration.

2+2+6+2+6+2+10+6+2+9=47

Silver has the Atomic number of 47.

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.
