Covalent and Ionic Compounds. What is the first statement of the video clip?
Hey everyone, it's James!
And in this video I'm gonna share a quick strategy to help you, help students differentiate
the difference between ionic and covalent compounds.
So let's get started [audio sound]
Now all you need is a periodic table, whether it's a gigantic periodic table like I have
here behind myself.
If you don't have that, you can project one up on the screen.
If you don't have that, you can always draw a periodic table on your white or blackboard.
And if you don't have that, get a piece of chart paper and draw on that as well. Now what I do is that I have the students stand up with me and then we point.
Metals are on one side of the periodic table, nonmetals are on the opposite side of the
periodic table.
When they come together [rubbing sound] they form the letter "I", for ionic compounds.
Covalent and Ionic Compounds. What is the second statement of the video clip?
Now when I talk about covalent compounds - two or more nonmetals.
So nonmetal, nonmetal.
When they come together they form the letter "C".

GROUP 18 ELEMENTS. what is the Twenty-Fifth statement of the video clip?
meanwhile radon is highly radioactive which is a characteristic that has been put to use in radiotherapy in attempts to cure cancer
these are the traditional uses of noble gases but it even goes beyond that
Krypton is sometimes used as a filler in double glazing set between two glass panels
Krypton will offer very good insulation because it has a lower thermal conductivity than the molecules making up the air and it doesn't stop

Group 2 - Alkaline Earth Metals. What is the first statement of the video clip?
welcome to moomoomath and science in this video. I'd like to talk about the alkaline earth metals
the alkaline earth metals are found in group 2 of the periodic table
they include beryllium (Be), magnesium (Mg), calcium (Ca), strontium (Sr), barium (Ba), and radium (Ra)
the alkaline earth metals share several common properties
they have low density, they are silver, and soft metals
Group 2 - Alkaline Earth Metals. What is the Second statement of the video clip?
they are ductile and malleable they react with halogens and water
the alkaline earth metals are found in group 2 of the periodic table

the alkaline earth metals share several common properties
they have low density, they are silver, and soft metals
Group 2 - Alkaline Earth Metals. What is the Third statement of the video clip?
they are ductile and malleable they react with halogens and water
alkaline earth metals are reactive but not quite as reactive as alkali metals
they include beryllium (Be), magnesium (Mg), calcium (Ca), strontium (Sr), barium (Ba), and radium (Ra)
the alkaline earth metals share several common properties
they have low density, they are silver, and soft metals
Group 2 - Alkaline Earth Metals. What is the Fourth statement of the video clip?
they are ductile and malleable they react with halogens and water
alkaline earth metals are reactive but not quite as reactive as alkali metals
this is because they all contain two electrons in their outer shell because they are reactive
