Parts and Locations of an Atom

A

Neutrons and protons are in the middle. Electrons are on the outside.

21
Q

(Blank) electrons form bonds

22
Q

Type of bonds

A

Covalent – shares

Ionic – give-and-take

Hydrogen – opposites attract

23
Q

Polarity

A

Example: water molecules. Attract each other. Positive and negative’s. Makes water cohesive, solvent, and expands when cold.

24
Q

Theory

A

Many hypothesis added together

25
Hypothesis
