What is listed in the periodic table? In the periodic table, what is a group? What is a period? Where are the metals and non-metals? For each element below, write which group it's in and how reactive it is likely to be. Pick the odd one out and explain why it's different from the others. What is the pattern of reactivity in this group? Write the name of each element below the description of its reaction with water. Circle what you think would happen if Sheena dropped a lump of calcium in water.
Understand the Problem
The question is examining various aspects of the periodic table, including definitions of groups and periods, properties of elements, and their reactivity. It asks for identification of metals, non-metals, and group members, as well as analysis of specific elements based on given criteria.
Answer
Groups are columns; periods are rows. Metals on the left, non-metals on the right. Reactivity varies by group.
The periodic table lists chemical elements. Groups are vertical columns showing elements with similar properties, while periods are horizontal rows. Metals are on the left, non-metals on the right. Reactivity varies within groups: Group 1 metals are very reactive, increasing downwards.
Answer for screen readers
The periodic table lists chemical elements. Groups are vertical columns showing elements with similar properties, while periods are horizontal rows. Metals are on the left, non-metals on the right. Reactivity varies within groups: Group 1 metals are very reactive, increasing downwards.
More Information
Elements in the same group share similar chemical properties due to their electron configurations. Group 1 elements, for instance, are known for their high reactivity with water.
Tips
A common mistake is mixing up groups and periods. Groups are vertical columns, not rows.
