Final answer:
Option C, 6.92 x 10^6, is the number written in scientific notation, which requires a coefficient between 1 and 10 multiplied by a power of 10.
Step-by-step explanation:
The number that is written in scientific notation from the options provided is C. 6.92 x 106. Scientific notation requires a number between 1 and 10 multiplied by a power of 10. For instance, the number 2,760,000 can be expressed in scientific notation as 2.76 x 106 since it is rewritten as the number 2.76 times the sixth power of 10.
This process effectively stabilizes the metal atoms involved, as the delocalised electrons enhance the attraction between the positively charged ions and maintain the structure of the metallic lattice. Therefore, the correct answer to the formation of a metallic bond is B. Atoms losing electrons, which allows the establishment of a bond characterized by a sharing of a pool of electrons among a lattice of cations.
