Will give brainliest, points, and more!!
tino4ka555 [31]

Do you relizes how many activities lead to global warming? When gas is burned in a car, it produces carbon dioxide (a green house gas). The carbon dioxide then floats up towards the atmosphere and becomes part of the atmosphere. This then causes the heat from the sun to get trapped, bouncing from the atmosphere to the earth. The sun will never stop producing heat which will only lead to the world getting hotter as each decade goes by.  

Hope this helps you!

Which of the following species has the greatest
Licemer1 [7]

Answer: Option (3) is the correct answer.

Explanation:

When there is a negative charge on an atom then we add the charge with the number of electrons. Whereas when there is a positive charge on an atom then we subtract the charge from the number of electrons.

Atomic number of chlorine is 17. So, number of electrons present in Cl^{-} is 17 + 1 = 18 electrons.

Atomic number of cobalt is 27. So, number of electrons present in Co^{4+} is 27 - 4 = 23 electrons.

Atomic number of iron is 26. So, number of electrons present in Fe^{2+} is 26 - 2 = 24 electrons.

Atomic number of vanadium is 23. So, number of electrons present in V is 23 electrons.

Atomic number of scandium is 21. So, number of electrons present in Sc^{2-} is 21 + 2 = 23 electrons.

Thus, we can conclude that out of the given species, Fe^{2+} has the greatest  number of electrons.
