C4 - Atoms and configuration
Cards in this deck (14)
- 1Electron configuration and the Periodic Table.
- 2First Electron ShellCan only have 2 two electrons
- 3Second Electron ShellCan hold 8 electrons
- 4Third Electron ShellCan only hold 8 electrons also.
- 5Can outer shells be filled if the inner shells are not?NO! The inner shells have to be full before the next shell can be used.
- 6—- This is neon electron
- It has two shells
- Neon can also be written as 2,8
- 2 electrons in the inner ring and 8 in the outer
-If it had one more electron another shell would be needed.
It is in group 8, we know this because there are 8 electrons in the outer shell - 7—- This is a sodium atom
- Sodium can be written 2,8,1
- It has 3 shells as the two inner shells are full meaning the remaining electron needs to be on the outside.
-It is in group one, we know this because of the amount of electrons on the outer shell.
- 8What does the horizontal row tell us about the configurationThe horizontal row on the periodic table tells us how many rings there are needed to be in the atom.
- 9Atoms with a full outer shellAtoms with a full outer shell are more stable, atoms need to either gain or loose electrons to do this.
- 10Atoms in group oneAtoms in group one aare all very reactive as they only need to loos one electron to get a full outer shell.
- 11Electrons in orbitElectrons are held in orbit because of the positively charged nucleus pull on the negatively charged electron
- 12What does it mean for the outer electron shell to be further from the nucleus?The atoms with more shells, tend to loose electrons more easily as the pull between nucleus and electrons is not as strong. Therefore they can be lost more easily.
- 13What is a diatomic moleculeA diatomic molecule is a pair of atoms.
