Does the central atom in a molecule the one with the highest electron?

Answer 1

False.

There are many examples where the statement is true and many where it is false.

Sometimes it is as in CH4, sometims it isn't as in CCl4. Carbon has an electron affinity of 122, hydrogen is 73, and chlorine is 349

Answer 2

Sometimes.

Taking the definition "electron affinity is the energy released when an electron is added to a neutral atom" and using figure from Wikipedia table (article electron affinity)

Here are a few examples (electron affinities in kJ/mol)

Molecule Central atom E.A Other Atom E.A

CH4............. 122 ................. 73

CCl4 .............122 .................349

PCl5............. 72................. 349

CO2............. 122................. 141

SO2 .............200................. 141

(Sorry about the ... it was the only way I could find of spacing the table!)

Answer 3

Not necessarily. The central atom in a molecule is typically the one with the lowest ionization energy or highest electronegativity, as this makes it more likely to form bonds with other atoms.

Answer 4

True :)

Answer 5

True.

Answer 6

Yes
