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

Hoe many atoms equal one mole

6\.02x10^23 atoms(atm)

What is the Centi base unit

10^2

What is the Milli base unit

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)

How do you tell atomic radious

As you go down the periodic table the radios gets bigger, left to right gets it smaller

What is a covalent bond

Non-metal + Non-metal

What is a Ionic Bond

Metan and non Metal

What is a Non-Polar molecule

When the molecules are evenly distributed

What is a Polar molecule

When the molecules aren’t evenly distributed
