Ionic Bonding
An ionic compound is formed between these two things
What are two oppositely charged ions, typically a metal and a nonmetal?
A covalent bond is the attraction of two atoms to this
What is a shared pair of electrons?
The same element that can vary in physical and chemical properties
What is an allotrope?
The attractive forces between the positive end of one polar molecule and the negative end of another polar molecule
What are dipole-dipole forces?
Groups 1, 2, and 3
What are cations?
A covalent bond is formed between these two things
What are two non-metals?
The standard molecular shape
What is linear, trigonal planar, tetrahedral, trigonal bipyramidal, octahedral?
This theory states that pairs of electrons around an atom repel each other – this determines a molecule's shape
What is VSEPR theory?
Groups 5, 6, and 7
What are anions?
Atoms bonds form according to this rule
What is the octet rule?
This determines the shape of a molecule
What are negative charge centers repelling each other?
The attraction and repulsions between atoms, molecules, and surfaces, as well as other intermolecular forces
What are van der Waals forces?
Because Ionic Compounds are always neutral Ca+2 and F-, form this compound
What is CaF2
[#valence electrons]-[#lone electrons]-[bonding electrons/2]
What is the equation to find the formal charge?
The marks on a lewis structure represent this
What is the position of the outer shell electrons in a covalent compound?
The way of describing bonding in certain molecules or ions by the combination of several contributing structures
What is resonance?
Iron (II) phosphate
What is the name of the ionic compound Fe3(PO4)2?
Bond order by strength
What is strongest being triple bond, then double bond, then single bond?
Atoms held together by covalent bonds in a giant three-dimensional lattice structure
What is a covalent network solid?
How easily a substance will vaporize
What is volatility?
