Explanation:
It is more difficult to remove electrons from the second shell or energy level because of the imbalance between the positive nuclear charge and the remaining electrons.
- The amount of energy required to remove electrons in ground state of an atom is the ionization energy.
- The first ionization energy is the energy needed to remove the most loosely bound electron of an atom in the gas phase in ground state.
- The second energy has a greater nuclear pull as it is closer to the nucleus.
- Both potassium and silicon have the same number of energy levels.
<u>Answer</u>:
A precipitation is said to be complete precipitation when no further precipitate can be formed in the process.
<u>Explanation</u>:
Precipitation is the reaction of creating solid from the solution. In precipitation reactions, insoluble salts are formed when two solutions containing soluble salts are combined.
These two solutions contain different salts and have either cation or anion pairing. This reaction helps in the determination of ions in a solution. The solubility table is being used to predict the precipitation reaction. It occurs in solid when one solid’s concentration is above solubility.
