This is bohr model of argon
good luck
Answer:
Explanation:
Given elements:
Sodium
Fluorine
The ion Na⁺ is made up of 10 electrons, its electronic configuration is:
1s² 2s² 2p⁶
Ion F⁻ is made up of 10 electrons, its electronic configuration is:
1s² 2s² 2p⁶
These ions do not form +2 because they cannot attain stability by losing or gaining two electrons.
Sodium atom is made up of one valence electron. If it loses one electron, it will be isoelectronic with Neon.
Fluorine has 7 valence electrons, to attain stability, it must gain one electron to form an octet. This way it will be isoelectronic with Neon.
Losing or gaining two electrons will not make the elements attain stability.
Answer:
substance
Explanation:
A mixture is when two or more <u>different</u> atoms/molecules are together, but not joined.
A substance is when the <u>same </u>atom/molecule is in a group together.
In this example, it is a substance because it is comprised of the same molecule not joined all together. If you wanted a mixture, other colored atoms/molecule (e.g. add green atoms) would change it to this property.
<span>For a particular redox reaction ClO2– is oxidized to ClO4– and Fe3 is reduced to Fe2 . The balanced redox reaction is expressed as:
</span>
4OH-+ClO2- + 4Fe^3+ ---> ClO4- + 4Fe2+ + 2H2O
Hope this answers the question. Have a nice day.
