Answer:
2 electrons
Explanation:
Oxygen has 6 valence electrons and to be stable it needs 8. That means it needs 2 more electrons to have a full octet.
Answer:Basic
Explanation:
The pH value of the acid is 10.0 which falls within the range of basic substances. A neutral substance has a pH of 7. Any substance with pH greater than 7 is basic while pH less than 7 is for Acidic
As you go down group 7 the melting point of the elements will increase, this is because as you go down the group you are gaining an electron shell and the molecule will become bigger. This increase in size means that there will be an increase in the intermolecular forces as well.
So the order would be NF3, NBr3, NI3.
