Atoms Flashcards
Explain a useful appilcation of Carbon-14.
Used for radio carbonating in determining age of fossils
Why do atoms form chemical bonds?
They want to be stable with balance electrons for a full outer shell
How many electrons are on the first level?
2
How many electrons are on the second level?
8
How many electrons are on the third level?
18
What are the two types of covalent bonds?
Nonpolar and polar
What has to be present in order for a covalent bond to be considered polar?
A positive and negative charge
The intra in intramolecular means?
inside
The inter in intermolecular means?
between
Maximum amount of hydrogen bonds a water molecule can have?
4
Why would it be more appropriate to refer to hydrogen bonds as hydrogen “attractions”?
Dipoloe-Dipole attraction between electronegative atoms
Between what atoms can a hydrogen bond form?
Electronegative
Examples: N, F, O
Place the 3 bond types from STRONGEST to WEAKEST

Explain how electronegativity relate to ionic bonds.
negative and positive charges
Explain how electronegativity relate to polar bonds.
Particle positive and negative charges
Explain how electronegativity relate to nonpolar bonds.
