Answer: The correct answer is option B.
Explanation:
- Ionic bond is formed when there is complete transfer of electrons from one element to another.
- Covalent bond is formed by the sharing of electrons between two elements.
- Metallic bond is formed when two metals combine together.
Electronic Configuration of Group VII-A :
This group require 1 electron to attain stable electronic configuration.
Electronic configuration of Group I-A :
This group will loose 1 electron to attain stable electronic configuration.
So, there will be complete transfer of electron from Group VII-A to Group I-A and hence, will form ionic bond between them.
Hence, the correct option is B.
Li (3)
N (7)
F (9)
Depends on if you are putting them in smallest to greatest.
Answer:

Answer: 130.2 g
Explanation:
To calculate the moles :
According to stoichiometry :
3 moles of require = 2 moles of
Thus 1.11 moles of will require= of
Mass of
Thus 130.2 g of gallium chloride would react with excess fluorine to produce 78.9 g of chlorine
Answer:
"Nuclear energy originates from the splitting of uranium atoms – a process called fission. This generates heat to produce steam, which is used by a turbine generator to generate electricity"
