Use the periodic table to determine which elements are likely to have a larger atomic radius than silicon (Si). Check all that apply.
Atomic radii from the top to the bottom of a group tend to:
A magnesium ion is than a sodium ion.
A chlorine ion is than a phosphorus ion.
A potassium ion is than a sodium ion.
Electronegativity down a group:
Describe the trends in atomic radii by checking the correct box. Atomic radii from the left to right across a period tend to:
Use the periodic table to compare the sizes of ionic radii with the corresponding atomic radii or other ionic radii. Choose from smaller and larger in the blanks below: A sodium cation is than a sodium atom.
Use the periodic table to answer the following question:What are the periodic trends of ionic radii? Check all that apply.
What is the predicted order of first ionization energies from highest to lowest for beryllium, calcium, magnesium, and strontium?
Why are the trends and exceptions to the trends in ionization energy observed? Check all that apply.
What are the trends and exceptions to the trends in electron affinity? Check all that apply.
