What is the general trend of atomic radius down a group in the periodic table?

Back

Atomic radius generally increases down a group.

Front

What is the significance of the p block in the periodic table?

Back

The p block contains elements with their outermost electrons in p orbitals, including nonmetals, metalloids, and some metals.

Front

How do you determine the number of valence electrons for an element?

Back

The number of valence electrons is determined by the group number of the element in the periodic table.

Front

What is the electron configuration for an element in the d block?

Back

The electron configuration for d block elements includes filling d orbitals after the s orbitals of the same principal energy level.
