Which statement describes the general trends in atomic radius and first ionization energy as the elements in Period 3 are considered in order from Na to Cl? (1) Atomic radius increases, and first ionization energy decreases.

(2) Atomic radius decreases, and first ionization energy increases.

(3) Atomic radius and first ionization energy both increase.

(4) Atomic radius and first ionization energy both decrease.

Ais the correct answer

The molar mass of a substance is defined as the mass of 1 mol of that substance, expressed in grams per mole, and is equal to the mass of 6.022 × 10 23 atoms, molecules, or formula units of that substance.

Sink to the bottom. addition of potassium nitrate past it’s dissolution capacity at a particular temperature will cause the extra to just sink to the bottom of the glass.however, if you were to raise the temperature of the solution prior to dissolving it, and then slowly decrease the temperature after the dissolution, you would create a “supersaturated” solution - a solution that has more solute dissolved into it than should be allowed. if you add any extra solute past this, the entire solution would “crystallize,” and this is how you get those cool videos on youtube.
