In the VSEPR model, the geometry of the regions defined by the electron pairs in the valence shell of an atom is called the electron-pair geometry. H
A. The Lewis diagram for SiH, is:
H-Si-H
1
H
The electron pair geometry around the Si atom in SiH, is
There are unshared pair(s) around the central atom, so the geometry of the SiH, molecule is

B. The Lewis diagram for CH20 is:
C с
H H
Recall that for predicting geometry, double and triple bonds count as only one electron pair region.
The electron pair geometry around the Catom in CH20 is
There are unshared pair(s) around the central atom, so the geometry of the CH2O molecule is

Why is the bond angle in a water molecule less than the bond angle of methane? a. the central oxygen atom in water has two lone pairs of electrons, whereas the central carbon atom in methane has no lone pairs. b. the central hydrogen atom in water has one lone pair of electrons, whereas the central carbon atom in methane has two lone pairs. c. the central oxygen atom in water has four lone pairs of electrons, whereas the central carbon atom in methane has only one lone pair. d. the central oxygen atom exerts more repulsive force on surrounding atoms than the central carbon atom in methane does. reset next

Can someone me with 6 to 10 plz this is for masteries test.

Listenbase your answer to the question on the information below.nuclear radiation is harmful to living cells, particularly to fast-growing cells, such as cancer cells and blood cells. an external beam of the radiation emitted from a radioisotope can be directed on a small area of a person to destroy cancer cells within the body.cobalt-60 is an artificially produced radioisotope that emits gamma rays and beta particles. one hospital keeps a 100.0-gram sample of cobalt-60 in an appropriate, secure storage container for future cancer treatment.which choice represents the correct product for the beta decay of the co-60? fe-60ni-60fe-61ni-61
