Where is the atomic number in an element box on the periodic table?
Top left of the element box
What is the bond between Na & Cl referred to?
It’s referred to as an ionic bond.
What is an IMF?

what are the names of IMFs
London Dispersion, Hydrogen Bond, Dipole-Dipole
What is the Formula to convert Celsius to Kelvin?
C + 273 = K
What is the analogy behind synthesis?
A couple is formed
What are defined as the electrons in the outermost orbitals?
Valence electrons
What is a Cation?
A positively charged ion.
How do you draw a IMF

What is Boyle's Law?
The relationship between the pressure and the volume of a gas.
What's the difference between Single Replacement and Double Replacement?
Single replacement only changes/switches 1 thing with another, while double replacement switches 2 different variables.
The octet rule states that atoms tend to ______
Gain, lose, or share electrons in order to acquire a full set of eight valence electrons
Given NH 3 what is the number of valence electrons the molecular shape?
10
Is Hydrogen bonding a bond?
No
The relationship between volume and the temp of a gas is the example of what Law?
Charles Law
What is the product equation of combustion?
CO 2 + H20
why does ionization energy decrease as you move down a group in the periodic table?
The outermost electron is held less tightly which means its easier to move.
What type of chemical reaction involves the breaking of chemical bonds to form new products, and is typically accompanied by a release of energy?
: Decomposition Reaction
What is the weakest IMF
London Dispersion Forces
What is the difference between a direct and inverse relationship?
Direct relationship both values increase and decrease at the same time while inverse one value increases the other decreases.
What is it when 2 compounds react to form 2 new compounds?
Double displacement ( replacement)
