Answer:
The rate at which the air temperature changes with height in the atmosphere surrounding a cloud or a rising parcel of air. The overall average rate is a decrease of about 6.5°C/km, but the rate varies greatly in different regions of the world, in different airstreams, and at different seasons of the year.
Answer:
Valence electrons
Explanation:
The formation of phosphorus trifluoride is orchestrated by the sharing of the valence electrons between phosphorus and fluorine.
This is called covalent bonding. In covalent bonding, elements with zero or very small electronegativity combines together. Such bonding occurs between non-metals.
For this bond to form, phosphorous shares its 5 electrons with the 3 of the fluorine.
