Which statement is true about the ionic size of the elements in a group as one moves from top to bottom in that group?
nekit [7.7K]

Answer:

Ionic size increases from top to bottom within the group.

Explanation:

  • Ions are formed when neutral atoms of elements gain or lose electron(s).
  • The ionic radius is the distance from the nucleus of an ion to the outermost energy level.
  • The ionic size or radius increases down the group as the number of energy level increases.
  • Therefore, an ion of an element lower in the group will be larger than the ion of an element higher in the group.
  • For example, an ion of potassium, K+, is larger in size compared to the ion of sodium, Na+ since K+ has more energy levels than Na+.

Explain how the effects of nuclear charge and the increasing number of core electrons in an atom oppose each other.
Kipish [7]
The nulear charge is the number of protons.

As the number of protons increases, the nuclear charge grows ant thhe pulling electrostatic force between them and electrons also grows, given that the electrostatic force is proportional to the magnitude of the charges.

As the number of electrons grows, they occupy outer shelss (farther from the nucleus). And the outer electrons will feel not only the atraction of the protons from the nucleus, but the repulsion of the inner electrons.

Then, we see that the increase of nuclear charge is opposed by the increase of core electrons, and the outer (valence) electrons are not so tied to the nucleus as the core electrons are.

This is called shielding effect. A way to quantify the shielding effect is through the effective nuclear charge which is the number of protons (Z) less the number of core electrons.

The more the number of core shells the greater the shielding effect experience by electros in the outermost shells.

The shielding effect, explains why the valence eletrons are more easily removed from the atom than core electrons, and also explains some  trends of the periodic table: variationof the size of the atoms in a row, the greater the shielding efect, the less the atraction force felt by the outermos electron, the farther they are and the larger the atom.

What does your data indicate about the optimum ph level for this enzyme-catalyzed reaction?
mestny [16]
At an optimum pH of 7.0, there are more molecules per minute in all amounts of substrate thus this pH is ideal for maximum growth. 5. Enzymes function most efficiently at the temperature of a typical cell, which is 37 degrees Celsius. Increases or decreases in temperature can significantly lower the reaction rate.
