Atoms of elements in Group 2A of the periodic table __________.
A) are much larger than their anions
B) are much larger than their cations
C) are much smaller than their cations
D) are equal in size to their cations
2.
Why are the atoms of elements in Group 6A much smaller than their anions?
A) Anions gain electrons when an ion is formed, making them larger than the atom.
B) Group 6A nonmetals lose electrons when they become anions.
C) Atoms of elements in Group 6A are actually much larger than their anions.
D) Although Group 6A elements gain electrons to become anions, the anion is not larger than the atom.
3.
Which group of elements on the periodic table contains atoms that are larger than their cations?
A) Group 7A
B) Group 1A
C) Group 2A
D) Both b and c
4.
How is the size of an atom measured?
A) By using atomic number
B) By using ionic radii
C) By using atomic radii
D) By measuring with a ruler
5.
What happens to the radius of an atom when the atom gains electrons?
A) The radius decreases in size
B) The radius increases in size
C) The radius does not change size
D) The radius is always twice as large in size
