Answer:
120, 180,90
Explanation:
According to VSEPR theory with a central atom with 5 gropus, we will expect a trigonal bipyramidal structure. This structure look like a trgonal plane containing the three iodine atoms, and above and below this plane we have the two bromine atoms 180º apart. Why can we say this? The key is that the problem is telling us the PIₐCl₂ is a nonpolar molecule and this shape is the only one that will result in a nonpolar structure. The Chlorine atoms will be in the axial positions 180 degrees apart and the bond angles will be :
I-P- I 120º
Cl-P-Cl 180º
I-P-Cl 90 º
See attachment.
The two Cl atoms are in the axial positions, and the three I atoms are in what we call equatorial position in the trigonal plane.
Any other arrangement will result in a polar molecule. Place a Cl atom in the trigonal plane and I in the axial position, and you can see that the molecule will be polar because the positions will no longer be equivalent and the dipoles will not cancel each other.
Many atoms if they are radioactive isotopes will loss protons and neutrons as radiation in order to gain and become more stable
hope that helps
Answer:
True
Explanation:
Because atoms with the same number of valence electrons react in similar ways with other elements.
Give the guy brainliest i dont know so give it to him
Answer:
False
Explanation:
A liquid has a definite shape and takes on the volume of its container. A gas has both the shape and the volume of its container. The particles in a gas cannot be compressed into a smaller volume. Liquids tend to contract when heated.
