Chemical Bonding
If electronegativity difference between atoms is equal to or greater than 2.0, they will form this type of chemical bond.
What is Ionic?
It tells us the actual numbers of atoms and how many of each type of atom are present in a molecule.
Molecular Formula
This state of matter will take the shape of its container.
What is a liquid?
the amount of moles of water in glucose (C6H12O6)
6 moles of H2O in glucose C6H12O6
How do you find an element's atomic mass?
Add the number of neutrons and the number of protons together
Chemical bond in which valence electrons are joined in electron pairs.
What is Covalent Bond?
11.25% C, 88.75% Cl; mol. wt. = 320
C3Cl8
This state of matter fills an entire space.
What is a gas?
mass of ionic compound
formula mass
What does the term 'valence electrons' mean? (2 things)
number of electrons on outermost shell, tells how reactive an element is
Chemical bond in which electron(s) from a metal are stripped and added to a nonmetal.
What is Ionic bond?
TRUE OR FALSE? An empirical formula is always the same as the molecular formula?
FALSE! A molecular formula is either the empirical formula or a multiple of the empirical formula.
This state of matter will not change its shape.
What is a solid.
molecular formula C6H12 (H 14.4% C 85.6%)
molecular formula C6H12
How do you figure out the number of neutrons?
Subtract the atomic number from the atomic mass
A covalent bond between two atoms, with 4 electrons being shared across one single bond would be this type of covalent bond.
What is Double Covalent Bond?
65.45% C, 5.45% H, 29.10% O; mol. wt. = 110
C6H6O2
In this state of matter, the particles flow past one another because they are held loosely together.
What is a liquid?
molar mass of oxygen
16 grams
What number tells you the number of protons and electrons?
Atomic Number
This is the reason atoms form chemical bonds.
What is Fill octet and Move to lowest PE possible

C4H5N2O
The particles are held together firmly and they jiggle or vibrate very fast in place.
What is a solid?
shows the shape, how atoms are arranged in a molecule
What is structural formula?
