Explanation:
Atom = Mole / 6.0221415E+23
1 Mole = 6.0221415E+23 Atom
Ionic bonds are formed from the attraction of oppositely charged ions in a chemical compound
Iodine has an electronegativity of 2.5, and potassium has an electronegativity of 0.8, so the difference is:
2.5 - 0.8 = 1.7
Answer:
While Bohr's atomic model hypothesizes that electrons move in particular energy levels around the nucleus, the electron cloud model suggests that electrons move in an unpredictable pattern but are more likely to be in certain regions than others.
Answer: 1.91cm3
Explanation:
10.49g of silver dissolves is 1cm3 of solution.
Therefore 20g of silver will dissolve in = 20/10.49 = 1.91cm3 of the solution.
