periodic trends in reactivity lab\nintroduction: the structure of the periodic table is such that elements with similar properties are aligned vertically in columns called \groups\. the reactivities of the elements follow well - defined trends both within the group and across a given row. in this experiment, you will explore these trends in reactivity for the elements. elements in the periodic table are organized by increasing atomic number. as atomic number increases so does the number of electrons. electrons, and specifically valence electrons, are important in determining how an atom interacts with other atoms. the elements in a group (vertical column) have similar properties because they have valence electrons in similar configurations. the elements in the periodic table are divided into categories. not only is this system useful for finding element but much can be predicted about an element based on its position on the periodic table.\npurpose: to explore the reactivity trends of metals in groups and periods of the periodic table.\npre - lab: prior to the lab, answer these questions.\n1. what are groups? what are periods? what are families?\n2. in general, where are metals located on the periodic table?\n3. what are the names of two metal families? alkaline metals, alkaline earth metals.
Answer
Brief Explanations:
- Groups are vertical columns in the periodic table. Periods are horizontal rows. Families are another name for groups.
- Metals are generally located on the left - hand side and in the middle of the periodic table.
- Two metal families are alkali metals and alkaline earth metals.
Answer:
- Groups are vertical columns. Periods are horizontal rows. Families are the same as groups.
- On the left - hand side and in the middle of the periodic table.
- Alkali metals, Alkaline earth metals.
