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.
Answer:
The number of protons also determines the identity of the element. ... Since the atom is electrically neutral, the number of electrons must equal the number of protons.
Covalent bond a chemical bond formed by two electrons that are shared between two atoms

Answer:
A) An Alkaline
Explanation:
An alkane that is pentane which is substituted by a methyl group at position 3. It is used as a solvent in organic synthesis, as a lubricant and as a raw material for producing carbon black.
