Ch 10 Ionic and Covalent Bonding

Cations have a

• positive charge

• negative charge

• neutral charge

• no charge at all

A lattice is held together between _____ by oppositely charged cations and anions

(Select all that apply) Lattice energies

• the energy required to completely separate one mole of a solid ionic compound into gaseous ions

• defined as an 'amount' of energy

• the energy required to not completely separate one mole of a solid ionic compound into gaseous ions

• are always positive

Octet rule wants to reach how many valence electrons

• 3

• 2

• 8

• 10

True or False: Electrons are extremely small particles and their properties are more wavelike than particle-like. They are thought of as charge clouds that occupy shapes of orbitals.

Covalent bonds/electrons being shared in a Lewis structure can be noted as

• dots

• pairs of dots

• arrows

• dashes

Single/Lone electrons can be noted as

• dots

• dashes

• arrows

• double arrows

From strongest -> weakest, put the bond strength in order

• triple > double > single

• single < double < triple

• single > double > triple

• triple < double < single

Electronegativity increases from

• left to right across a row

• right to left across a row

• bottom to top within a group

• top to bottom within a group

Do noble gases have electronegative?
