The Elements

In their search for the primary matter, the alchemists helped to establish the-

• periodic table

• groups of elements

• families of elements

• scientific method

Cannot be broken down-

• Elements

• components

• segments

• portions

The periodic table classifies elements according to their-

• properties

• structures

• reactivity

• alkalinity

Horizontal rows on the periodic table are called-

• groups

• families

• periods

• metals

Within the period, as you read from left to right the atomic number -

• increases

• decreases

Elements in the vertical columns on the periodic table are called-

• groups

• families

• groups or families

Elements within a group have similar-

• properties

• structures

• reactivity

• alkalinity

Elements that are so reactive that they are never found alone in nature-

• alkali metals

• alkaline earth metals

• transition metals

Name of Elements in Group 1

• alkali metals
