Elements are arranged so that the ones with similar chemical and physical properties are stacked in vertical groups, and there are 8 groups (see the numbers at the top?) with either an A or B after the number? I know they’re written in Roman… just remember that IV means four, and VI means six. Sometimes you’ll see them numbered 1-18 starting with hydrogen on the left.

The rows are called periods. Now point to the metals… what colors are those? There are lots of them!

Ok! Thank you so much Mrs. Aurora!
Kelvin is the units for the absolute temperature scale. For example, zero degrees Celsius is also 32 degrees Fahrenheit which is also 273 Kelvin. It’s like measuring something with a different ruler, like inches, centimeters, etc. For more on temperature specifically, visit Unit 13 and watch the special science teleclass!
What is Kelvin? Is it a chemical on the periodic table used for heating things, or is it a chemical used for mixing wth other chemicals for experiments?
That was a wonderful lesson, thank you!:)
Oops, thanks for checking! It’s available here:

Where should I look for the video mentioned at the end of this wonderful lesson about the periodic table? I think the video is about the first column of metals interacting with water.
