Answer:
The answer to your question is: B and C.
Explanation:
Neon atomic number = 10
Electron configuration is not : 1s²2s¹2p⁶ .
This electron configuration is for fluor (9 electrons) because is we sum up the electrons ( 2 + 1 + 6) the result is 9.
A)The 3s orbital should be part of the configuration. This is not the right reason.
B)The total number of electrons is incorrect. This correct, the number of electrons is 9 instead of 10.
C)The 2s orbital does not have enough electrons. This option is correct, 2s must have 2 electrons and it only has 1.
D) The 1s orbital does not have enough electrons. This option is incorrect, 1s orbital can have only 2 electrons.
Iron(II) oxide react with nitric acid to produce iron(III) nitrate, nitrogen dioxide and water. Chemical reaction<span>. Balancing </span>chemical<span> equations.</span>
Answer: Potassium to fluorine, fluorine to nitrogen, bromine to hydrogen, carbon to hydrogen, lithium to chlorine, sodium to chlorine.
Explanation:
Ionic bond is greater when the electronegativity difference existing between the two atoms are large causing the bonding to be more polar.
