Ionic Bonding
A chlorine anion has this many Lewis dots.
What is 8?
Pattern in which a crystal is arranged.
What is a lattice.
When discussing molecular geometry, these two things affect the geometry of the molecule (as we have covered so far)
What are the number of atoms bonded to the central atom and the lone pairs on the peripheral (B) atoms?
Why do pieces of salt have cubic shapes?
The arrangement of cations and anions such that there is one Na+ for 1 Cl- creates a cube shaped lattice
This is the greatest number of covalent bonds which can form between just two atoms.
What is 3 covalent bonds?
These elements will (never) have no more than two Lewis dots
What are hydrogen and helium?
The joining of atoms to from new substances.
What is a Chemical Bonding
Atoms become ions because of this.
Atoms gain electrons to fill their outermost energy level or make a lower energy level the source of their valence electrons
This is formed when two atoms join through covalent bonds.
What is a molecule or a compound (if it involves 2 or more different elements)
Lewis dot structure for ionic compounds will show the Lewis dots and...
What is the charge for each ion?
The outermost layer of electrons.
What are Valance Electrons
Name 2 properties of ionic bonds
What are they are Soluble in Water, have a High Melting Point, or have a High Boiling Point/High Point of Vaporization.
Atoms form bonds to maximize their number of valence electrons (8), as explained by this rule.
What is the octet rule?
When drawing a Lewis dot model, a triple covalent bond is represented by this.
What are six dots between two atoms or 3 dashes between two atoms.
A charged atom that forms when an atom gains or loses electrons.
What is an Ion
Hydrogen is an exception to the octet rule in covalent bonding because of this.
What is the maximum number of their valence electrons is 2?
Atoms that can take on more than 8 valence electrons/ 8 Lewis dots are those that also have this. (we touched on this but were told this is not on the test)
What is a d orbital?
Cations are normally formed from atoms in these groups:
What are groups 1/IA and 2/IIA?
