Atoms
What are atoms?
The smallest particle of an element
What is dimensional analysis?
It is a versatile mathematical approach with multi-step calculations
What is the number of one mole?
6.02x1023
What step is the first step of mass spectrometry?
Ionization
Protons are what
Positive!
The net charge of an atom found is by adding a proton and an electron.
What is molar mass?
It is the mass of one mole of element or compound in a gram
How do you find molar mass?
By looking at the atomic mass of the element on the periodic table
What is the second step?
Acceleration
Electrons are?
Negative!
Dalton stated that blank are formed by a combination of two or more different kinds of atoms
Compounds
What is the molar mass of NH3?
17.03
What is a mole?
Measure of the amount of particles in matter
What is Deflection and what happens?
The stream of POSTIVLEY charged ions are deflected
What is the mass of an electron?
.00055
The atomic number is the number of what
The number of protons
What unit do you use for molar mass?
(g/mol)
What is the molar mass of AgNO3?
169.87 g/mol
What is the rule of deflection and mass?
The lighter the mass of the ion, the more the deflection. The heavier the mass of the ion the less the deflection
Electrons are located where
Outside of nucleus
What is an Ion
When a neutral atom gains or loses electrons, it becomes charged
What is the molar mass of CaCO3?
100.08 g/mol
