The intrument that tells both the speed and direction of the wind is the?

anemometers

Modern instruments used to measure wind speed and direction are called anemometers and wind vanes, respectively. These types of instruments are used by the wind energy industry, both for wind resource assessment and turbine control.

the number of valence electrons for each molecule or ion is shown beneath the structure. remember hydrogen will not have more than two electrons. this hydrogen is part of a covalent bond (sharing two electrons). a double bond here would cause hydrogen to share four electrons with phosphorus.

the increase of protons   hope this
