Answer:
not sure but i think that there are 35 atoms.
Have a great day!
They held together by metallic bonds.
Hopefully this has helped! :)
Answer:
1.Magnetosphere
2.Liquid Outer core
3.Atmosphere
4.Lightening
5.Biosphere
6.Blue
7.Dolphins
8.Hydrosphere
9.Ice Caps
10.Lithosphere
11.Latitude
12.Longitude
Explanation:
The invisible field that protect us from solar radiation is called Magnetosphere.
This protective field is created by movement between solid inner core and earth's Liquid outer core.
The layer of gases is called atmosphere.
In addition to wind , rain , lightening is observed on stormy night.
Because of water earth looks Blue.
Dolphins are just one of the animals that calls the hydrosphere, its home.
Ice caps in the north and south poles.
Rocky layer of solid earth is part of Lithosphere.
Look for the latitude first ,horizontal line ...
Answer:
To have the electronic configuration equal to 1s²2s²2p⁶3s²3p⁶4s²3d⁷, the chemical element must have an electrical charge equal to 27, that is, it must have 27 electrons, such as Cobalt (Co), for example.
Explanation:
The electronic configuration shown in the question above is known as the Linus Pauling distribution and represents the energy sub-levels that an electrically charged atom can have in relation to the amount of electrons it has.
The layers sub-levels are presented in the following order 1s² 2s² 2p⁶ 3s² 3p⁶ 4s² 3d¹º 4p⁶ 5s² 4d¹º 5p⁶ 6s² 4f14 5d¹º 6p⁶ 7s² 5f14 6d¹º 7p⁶. Where the small numbers represent the number of electrons in each sub-level and the large numbers represent the layers of electronic distribution.
Accordingly, we can see that an atom that has the configuration 1s²2s²2p⁶3s²3p⁶4s²3d⁷ has 27 electrons, like Cobalt.
