Why is Hydrogen and Fluorine cannot be central atoms in Lewis dot structurs?

To be the central atom in a compound, the atom must be able to simultaneously bond to at least two other atoms. He, F, and H cannot serve as central atoms in a Lewis structure

Is the electronegativity of fluorine more than that of hydrogen?
Yes, fluorine is more electronegative than hydrogen : it has the highest elemental electronegativity by the Allen method, at 4.193 to hydrogen's 2.300 (only neon is higher than fluorine, but it cannot be calculated using Pauling units because it forms no ordinary compounds).
Can hydrogen and fluorine a group I and group VI element respectively cannot form multiple bonds?
Fluorine is in the group XVII. Both are monovalent elements.
Would the compound CH3CH2CH2CH3 form a hydrogen bond?
No, the compound CH3CH2CH2CH3 (butane) does not have any hydrogen atoms bonded to electronegative atoms such as oxygen, nitrogen, or fluorine. Therefore, it cannot form hydrogen bonds.
Why oxygen cannot have 9 protons?
Because if it did it would be Fluorine
How is fluorine extracted from its raw material?
Fluorine can be extracted through the electrolysis of an anhydride such as potassium fluoride, but cannot be separated chemically because the fluorine reacts with any newly introduced agent.
Is the electronegativity of fluorine more than that of hydrogen?
Yes, fluorine is more electronegative than hydrogen : it has the highest elemental electronegativity by the Allen method, at 4.193 to hydrogen's 2.300 (only neon is higher than fluorine, but it cannot be calculated using Pauling units because it forms no ordinary compounds).
Can hydrogen and fluorine a group I and group VI element respectively cannot form multiple bonds?
Fluorine is in the group XVII. Both are monovalent elements.
What is chlorofluorocarbon?
A hydrocarbon with all the hydrogen atoms replaced with either chlorine atoms or fluorine atoms. They cannot be all chlorine or all fluorine atoms, but must be some mixture.
Would the compound CH3CH2CH2CH3 form a hydrogen bond?
No, the compound CH3CH2CH2CH3 (butane) does not have any hydrogen atoms bonded to electronegative atoms such as oxygen, nitrogen, or fluorine. Therefore, it cannot form hydrogen bonds.
What is diatomic atoms?
HOBrFINCl Hydrogen Oxygen Bromine Fluorine Iodine Nitrogen Chlorine These when in elemental state cannot stand alone so the are written at H2, O2, ect.
Fluorine atoms cannot form a double or triple bond because fluorine?
Has a valence of 1.
How do you make a pure sample of fluorine?
No you cannot make a pure sample of Fluorine because it is an earth made element.
Why fluorine cannot be prepared by oxidation of fluoride ion?
Fluorine is so electronegative that there isn't really anything that can oxidize it.
Why oxygen cannot have 9 protons?
Because if it did it would be Fluorine
Why fluorine cannot form oxyacids?
Fluorine can not form oxyacids because fluorine is more electronegative than oxygen, and oxyacids are formed only from elements that are less electronegative than oxygen.
How is fluorine extracted from its raw material?
Fluorine can be extracted through the electrolysis of an anhydride such as potassium fluoride, but cannot be separated chemically because the fluorine reacts with any newly introduced agent.
Which elements will occur as diatomic molecules and cannot exist as individual atoms?
All elements can exist as individual atoms in excited states. However, at standard temperature and pressure, hydrogen, nitrogen, oxygen, fluorine, chlorine, bromine, and iodine exists as diatomic molecules.
