The Correct choices are :
- 1. The elements have filled valence levels.
- 2. potassium (K) with a 1+ charge
Answer:
Electron shielding is when the inner electrons shield the outer electrons from the full force of the nucleus
Gasoline is a mixture of compounds called hydrocarbons (compounds of hydrogen and carbon). It is obtained by purifying crude oil by fractional distillation. Gasoline is most commonly referred to as a mixture of compounds, therefore it is a mixture. Gasoline is composed of hydrocarbons combined with different concentrations of ethanol. <span>Pure substances can be either elements or compounds. </span>Mixtures<span> can be either</span>homogeneous or heterogeneous<span>. Another term for a </span>homogeneous mixture<span> is a solution. ... </span>Gasoline<span> is thus a blend of different compounds, so it is a </span>mixture<span>.</span>

Answer:
Kf
Explanation:
The stability constant Kf of a given complex specie is an equilibrium constant that represents the formation of that particular complex specie in solution. It measures the strength of the interaction between the ligands and metal that form the particular complex specie. The magnitude of Kf shows how easily a complex specie is formed in solution.
Hence if I want to dissolve the bromides or chlorides of silver which are ordinarily insoluble in water by means of complex formation, the magnitude of the stability constant for each particular complex specie is important as it gives information regarding the thermodynamic feasibility of the process.
