What are Physicals properties
A change in a property that can be observed. (change in color, change in texture, smell)
What are Chemical potteries
When a substance changes into a new chemical
What is the difference between Chemical and physical Changes
Physical is a change in texture or color, chemical is a new substance.
What is Heterogenous matter
Visually different
What is Monogenous matter
Stays the same no difference
What was Ruthfords ’s experiment
Found out the the atom is mostly empty with the gold foil experiment. He shot particles through a atom onto a gold foil and most of the atoms went through
What was JJ Thomson’s experiment
Discovered electrons with a cathode towards positively charged protons.
Alpha decay
Nucleus loses two protons
Beta Decay
Nucleus gains or losses one proton
What is the rule for measuring
write the known values down firs than en estimated one

10^3
What is the kilo base unit
10^-3
What are the three rules for writing electron configoration
Aufbau, hunds rule, and pauli exclusion principle
What is hunds rule
Each orbital must have one electron(arrow) before two
What is Aufbau
Electrons occupy the lowest energy level first
What is Pauli exclusion principle
2 elections in the same orbital have different spins
What is the red section
S2
What is the blue section
D10
What is the yellow section
P6
Explain the relation between ground and excited state
Ground to Excited - energy is absorbed
Excited to Ground - energy is released
What happens when an electron goes from excited to ground state
A photon of light is released. the color is determined on the amount of energy released. Purple is the most energy released and red is the least.
What color has the longest wavelengths
Red
What color has the shortest wavelength
Violate
What does C stand for in calculating wavelengths and frequency
speed of light
What does V stand for in calculating wavelengths and frequency
Frequency
What does E stand for in calculating wavelengths and frequency
Energy (J)
What does h stand for in calculating wavelengths and frequency
Planks constant 6.63x10^-34 JxS
What does λ stand for in calculating wavelengths and frequency
Wavelength (m)
