They are important because they are the electrons that help the atom to bond with another atom. They are in the outer most shell. ☺️
Answer:
Option B. [Ar] 4s² 3d⁷
Explanation:
The condensed form of the electronic configuration of of cobalt, Co can be written by using the closest noble gas element before the cobalt element.
Cobalt has atomic number of 27. The noble gas element before cobalt is argon (Ar).
Thus, we can write the electronic configuration of cobalt, Co as follow
Co (27) => [Ar] 4s²3d⁷
It would have to be 4.diffusion
Answer:Climate is defined as the average state of everyday's weather condition over a period of 30 years.[1][2] It is measured by assessing the patterns of variation in temperature, humidity, atmospheric pressure, wind, precipitation, atmospheric particle count and other meteorological variables in a given region over long periods of time. Climate differs from weather, in that weather only describes the short-term conditions of these variables in a given region.
