Electron configurations are a shorthand form of an orbital diagram, describing which orbitals are occupied for a given element. for example, 1s22s22p1 is the electron configuration of boron. use this tool to generate the electron configuration of arsenic (as).

[Ar] 4s² 3d¹⁰ 4p³

Explanation:

Arsenic has an atomic number of 33, thus 33 protons and 33 electrons. The electron configuration is:

1s² 2s² 2p⁶ 3s² 3p⁶ 4s² 3d¹⁰ 4p³

The shorthand notation includes the previous noble gas to represent the inner electrons. The gas previous to arsenic is argon, with 18 electrons. The shorthand notation for arsenic is:

[Ar] 4s² 3d¹⁰ 4p³

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.
