What is the Lewis structure for TeF6?

Answer 1

There are 42+5+1 valence electrons = 48

6 initial bonds, leaving 36 more electrons to distribute. These go around the F atoms.

so P as the central atom, and 6 single bonded F atoms around it. Structure is octahedral.

Answer 2

F(6 valance electrons)\ /F(6 valance electrons)

F(6 valance electrons)-Te-F(6 valance electrons)

F(6 valance electrons)/ \F(6 valance electrons)

68 electrons with 20 left over.

Te is a group 6

F is a group 7 with 6 times so that is 6+6(7)=68

H

(ch3)- so (ch3)4= 4- charge

Te +6 ion and F2- ions = 4+ charge

Te has 6 total valence electron pairs, 5 bonding, 1 not, VSEPR= AX5E, >90 degrees, square pyramidal.

Answer 4

S is the central atom with single bonds connecting it to 6 Fs with 3 lone pairs on each F.

Answer 5

trigonal pyramidal (AX3N), The PF3 bond angle will be about 109 degrees since it has a trigonal pyramidal molecular geometry.

Answer 6

Si is the central atom connected to 6 fluorine atoms with 3 sets of lone pairs on each fluorine atom.

Answer 7

It is Triangular Bipyrcamidal with a SP3d hybridization. A Lewis dot diagram would be drawn as phosphorus as the central atom, then the 5 fluorines surrounding the central atom.

Answer 8

AsF6-1
