The ability to summarize information is a vital component to understanding the information you read in your coursework. To summarize information:
• create a brief statement that explains the meaning of something much longer;
• decide what points are crucial to the main idea;
• put the information into your own words, i. e., how would you say it if you were the author?
OBJECTIVES

clouds form

solid ice forms on leaves.

water droplets form on grass.

the seeing the electronic configuration we can say that the element is fluorine.

fluorine is the most electronegative element in the periodic table.

but by only seeing the configuration we cannot say about its reactivity because we don't know if its configuration after excitation or by addition of electrons.

but if not then, it is the lightest halogen and exists as a highly toxic pale yellow diatomic gas at standard conditions. as the most electronegative element, it is extremely reactive: almost all other elements, including some noble gases, form compounds with fluorine.
