The ionic radius of an anion is always ______________ than the atomic radius of the equivalent neutral element.
Larger
Smaller
Equal
Challenge: In nerve cells, Sodium channels allow Na+ ions to pass easily while simultaneously blocking passage of K+ ions. What periodic trend is most likely the reason for this?
Potassium's ionic radius is larger than sodium and unable to fit into the opening
Potassium is more electronegative than sodium and binds to the channel
Potassium's ionization energy is larger than sodium's and is rarely present as an ion in solutions.
Potassium is a non-metal and takes on a negative charge while Sodium is a metal and takes a positive charge.
Given the following chart that shows the radius of neutral elements and their corresponding ionic radii in picometers (10-12 m), which of the following would be the best prediction for the radius of the Cl- anion?
The radius of Cl- ion is GREATER than 99 pm because it has fewer e-s than neutral Cl
The radius of Cl- ion is LESS than 99 pm because it has fewer e-s than neutral Cl
The radius of Cl- ion is EQUAL to 99 pm because it has the same NUMBER of e-s as neutral Cl
The radius of the Cl- ion is GREATER than 99 pm because it has more e-s than neutral Cl.
Which of the following reasons best explains why noble gases are NOT electronegative?
They do not attract electrons from other elements since they already have a full outer shell.
They need extra electrons to form an ion with a full outer shell.
They actually are electronegative because they are reactive.
Their effective nuclear charge is 0.
