Chlorine has two isotopes, chlorine-35 and chlorine-37. Give the number of protons, neutrons and electrons in each of these isotopes, and write their isotope symbols (ex. ??CI). What would you need to know about these two isotopes
in order to calculate the average atomic mass of chlorine? Based on the average atomic mass on the periodic table,
which isotope is most prevalent? How do you know?

warm front forms when a moist, warm air mass slides up and over a cold air mass. as the warm air mass rises, it condenses into a broad area of clouds. a warm front brings gentle rain or light snow, followed by warmer, milder weather.

each chemical family is represented as a group or column on the periodic table. based on chemical properties, there are 6 types of chemical families. group 1 represents alkali metals, group 2 represents alkaline earth metals, groups 3 to 12 represent transition metals, groups 13 to 16 represent non-metals and other metals, group 17 represents halogens and group 18 represents noble gases.
