introduced in this chapter. Each blank can be completed with a term, short phrase, or number.

The periodic table organizes the elements into vertical ________________ and horizontal ________________ in

order of increasing ________________. The table is constructed so that elements that have similar chemical properties are

in the same ________________. The elements in Groups 1A through 7A are called the ________________. The

________________ make up Group 0. The elements in Groups 2A and 3A are interrupted in periods 4 and 5 by the

________________ and in periods 6 and 7 by the ________________.

Atomic radii generally ________________ as you move from left to right in a period. Atomic size generally

________________ within a given group because there are more ________________ occupied and an increased

________________ effect, despite an increase in nuclear ________________.

The energy required to remove an electron from an atom is known as the ________________ energy. This

quantity generally ________________ as you move left to right across a period. The ease with which an atom gains an
