200
If two atoms have half-filled orbitals, the interactions balance at a small enough distance so the e–’s can be close to both nuclei at the same time
What is Covalent bond
200

How many pi bonds in a single bond?

What is 0?

200
must be named using mono-, di-, tri-, tetra-, penta-, hexa-, hepta-, octa-, nona-, deca-.
What is molecular compounds
200
is found by simply summing the atomic masses (on the periodic table) of each atom in a formula.
What is Formula or molecular mass
300
energy needed to remove an electron from an atom
What is Ionization energy
300
atomic symbol surrounded by valence electrons.
What is Lewis symbol
300

How many total sigma and pi bonds in CO2?

What is 2 sigma and 2 pi?

300
s do NOT use di-, tri-, etc. unless they are part of the ion name ionic compounds are named as the positive and negative ion.
What is Ionic compound
300
Actual Yield/ Theoretical Yield x 100
What is percent yield
400
As atoms or ions get larger, the electron being removed is farther from the nucleus… the attractions are less… the energy needed is less… the ionization energy is less.
What is Ionization energy trends
400
bonds have partial charges + and –
What is Polar bonds
