Q

why is it solid to gas on the periodic table?

A 
Metals= bigger, electrons are closer to one another 
Nonmetals= gas, electrons are farther away from each other

Q

why form an ion?

A

to fill the outer ring, which stabilizes it, requires less energy to be totally filled
closer to the nucleus- less energy

Q

what are bonds? what do they create?

A

Sharing or stealing of electrons when orbitals overlap
this creates compounds (compounds can be molecules or crystals)
made or broken in chemical reactions

Q

evidence of a chemical reaction

A 
color change
Precipitate (liquids to solids, has to liquid)
Odor       Light
Heat/cold     Fire     Sound
Bubbles
16
Q

what if the energy isn’t favorable to form a compound?

A

Just a physical change

17
Q

what do physical changes create? Chemical?

A

Physical-mixtures

Chemical-compounds

18
Q

do bonds occur in chemical or physical reactions?

A

Chemical

19
Q

Properties of a chemical vs physical reaction

A

Chemical- totally new properties from its element

Physical- has similar properties to its component

20
Q

Examples of a chemical reaction

A

Sodium chloride, NaCl- salt

nothing like salt

21
Q

Examples of physical reaction

A

Salt water, lemonade
