Good afternoon, Today i have completed my inquiry task for today and it was called Atoms doc. To complete this task i had to first watch a video and then after that i had to write the difference between Molecules and atoms. The difference between them is that Atoms are single neutral particles and Molecules are neutral particles that are made of two or more atoms bonded together. I enjoyed doing this task because it was easy to do, i hope you enjoyed looking at this blog post.:) I have also posted my google drawing of Water molecule h20; )
LI 5: We are learning that everything is made out of different combinations of atoms and that different materials have different properties.
Everything is made up of different combinations of these atoms. For example, water molecules are made up of two hydrogen atoms and one oxygen atom. That is why water is also called H2O.
What is the difference between a molecule and an atom?
Atoms are single neutral particles and Molecules are neutral particles that are made of two or more atoms bonded together.
Atoms also come in different sizes, depending on how many electrons they have. An oxygen atom is a lot (16 x) larger than a hydrogen atom. Draw a picture (and take a photo) or create an image on google draw of a water molecule H20. It contains 2 hydrogen atoms and one oxygen atom.
Example = this is a carbon dioxide atom.
Different materials have different properties. For example, they have different melting and boiling points, different mass (weight), density and some are stronger than others. This is caused by their molecular structure.
We need to keep this in mind when designing different products. For example, we make saucepans out of metal because they won’t melt on our stoves. However, if we tried to place a plastic pan on the stove it would melt because it has a lower melting point. We can create strong metal by
