How is electron movement related to covalent bonding in
ammonia, NH3?
A) Electrostatic
sharing in a sea of electrons around the atoms allows bonds to form.
B) The atomic orbitals overlap and electrons are shared between the atoms
forming bonds.
C) A transfer of electrons forms ions which are electrostatically attracted
forming bonds.
D) Orbital exchange occurs between the atoms to redistribute the electrons and
form bonds.
The electron
movement related to covalent bonding in ammonia, NH3 is The atomic orbitals overlap and electrons are shared between the atoms
forming bonds. The answer is letter B.
Answer:
lack of snow in the mountains makes drought cycles worse because mountains are a natural part of the water cycle.
Explanation:
Mountains play a critical part In the water cycle by capturing moisture in the air and it precipitates as snow and when it does this the snow will melt in the warmer seasons and flow down stream then following the rest of the water cycle if we didn't have this then the streams would run less and it would greatly disrupt the water cycle.
Answer: Extinction
Animals on the verge of extinction are considered endangered species. Some could argue that the phrasing "threatened" is synonymous to "endangered". Some classify extinction based on if the species is completely wiped out in the wild, or if the species is completely gone (both in the wild and in zoos for instance). Extinction events are not solely due to the changes in atmosphere, but also due to lack of food or habitat, among other possible factors.
