Formed when one or more electrons are transferred from one atom to another, metal + non metal
Do not conduct as solid but as liquid or dissolved conduct
High melting point: strong electrostatic bonds between ions
Soluble in water: water molecules slight electrical charge, attracting ions away from the lattice
what is Ionic bond
Moles of x (Atomic weight of X)
what is Moles to Grams
(KE) avg= 3/2 RT
The diagram that shows the bonding between atoms of a molecule and lone pairs of electrons that may have exist in the nucleus
what is Lewis Structure
There are two reactants in a chemical equation, and one product. The mass of the product is 30g. The mass of the first reactant is 17g. What must the mass of the second reactant be, if the equation is to follow the law of conservation of mass?
what is 13 g
a bond formed when atoms share one or more pairs of electrons, non metal + non metal
Molecular solids: low melting ans boiling points however larger solid stronger molecular forces
what is Covalent bonds
grams of x (1 mole/ atomic weight of X)
what is Grams to Moles
PV= nRT
what is Ideal Gas Law
States that atoms tend to combine in a way that they each have 8 electrons in their valence shell
what is Octet Rule
In a closed system, a chemical reaction takes place. The mass of the reactants in the beginning of the reaction is 25g. What does the mass have to be in the end of the reaction in order to follow the law of conservation of mass?
what is 25 g
a bond formed when atoms share one or more pairs of electrons, non metal + non metal
Molecular solids: low melting ans boiling points however larger solid stronger molecular forces
what is H2S=17 g
assume 100 grams. %# (100 grams of X) = grams of X
