Fluorine in compounds is always assigned an oxidation number of -1
They drill too deep and find lava
<u>Answer:</u>
It helped biologists collect data on when and where turtles travel.
<u>Explanation:</u>
Green sea turtles need to be conserved so the biologist take help of satellites in order to track down green sea turtles.
The tracking of green sea turtles can be done by the help of satellites as satellites send a signal whenever these turtles come to surface of water to breathe which can then be used to prevent the turtles from getting caught by poachers.
Answer:
The shape of the BF3 molecule is best described as trigonal planar.
Explanation:
The Lewis Structure for BF3 is like this:
_ _
| F | | F |
\ /
B
|
| F |
---
It forms three angles of 120° each. The bonds are in the same planar that's why it is trigonal planar and they are exactly the same.
Boron and Fluorine have 3 covalent bonds, produced by electronic promotion that enables the 2py and 2pz orbitals, leaving an electron to pair in the 2px. So boron will have 3 possible electrons to pair in 2s1, 2px and 2py, remember that electronic configuration for B is 1s2, 2s2, 2p1
By hybridization between the orbitals 2s2 and 2p1, the electrons of F, can joined to make the covalent bond. The new B configuration is 1s2, 2s1, 2px1, 2py1 (these last three, hybrid orbitals)
