Groups of the Periodic Table
The group of elements that do not want to bond.
What are noble gases?
Two or more atoms sharing electrons.
What is a covalent bond?
An element that has lost an electron.
What is a cation?
Dissolved in water ionic compounds conduct electricity.
What is conductivity?
I could gain or lose electrons, bonding up to four times.
What is carbon, silicon, germanium...?
The group that only needs one electron to be 'content'.
What are the halogens?
A transfer of electrons takes place rather than sharing
What is an ionic bond?
The RIGHT side of the periodic table tend to form this type of ion.
What is an anion?
Graphite, a form of covalently bonded carbon, breaks easily.
What is brittle?
A Lewis Dot Structure can hold up to this amount of electrons per side
What is two?
The group that forms +1 ions.
What are the alkali metals?
This type of bond creates a sea of electrons.
What is a metallic bond?
The tendency for most elements to be stable when they have 8 electrons in their outer shell
What is the octet rule?
Type of bond that allows these elements to be malleable and ductile.
What are metallic bonds?
Determines HOW an atom bonds and as a result, an elements chemical properties
What are valence electrons?
The second most reactive group of metals.
What are the alkaline earth metals?
Type of bond where atoms share electrons EQUALLY.
What is a non-polar covalent bond?
A mixture of two or more metals whose properties are superior to each of the individual metals.
What is an alloy?
Type of bond that creates compounds where the elements are typically liquid or gas.
What is covalent?
The attracting force between and the nucleus and electrons or a cation or anion
What is electrostatic force?
The group which can form various cations.
What are the transition metals?
Bond in which atoms share electrons but one atom tends to 'hog' them, the electrons are not shared equally.
What is a polar covalent bond?
In a water molecule, oxygen 'pulls' hydrogen's electrons away from hydrogen closer to oxygen.
What is electronegativity?
Causes a molecule to be polar
What is electronegativity?
Achieves electrical and chemical stability
What is why an atom bonds?
