Why do atoms form bonds?
Atoms in compounds produced by bonding are more stable than the individual atoms that form them.
When hydrogen and oxygen are combined they create what?
Water
What is an electrostatic attraction that forms between atoms when they share or transfer valence electrons?
chemical bond
Atoms can have better stability in how many ways?
2
Chemical bonds do what?
Store useful energy within molecules
What are the 2 ways that an atom can meet the octet rule requirements?
By sharing electrons or by transferring (gaining/losing) electrons.
Groups of atoms bonded together as compounds are usually more stable than those individual atoms would be by themselves. True or False
True
A chemical bond forms when atoms either share or _______ electrons.
transfer
Define "octet rule"
The octet rule dictates that atoms are most stable when their valence shells are filled with eight electrons.
When are atoms generally most stable?
When they have a full 8 electrons in their valence energy level.
Are molecules always made of atoms of different elements? Explain
No. Some elements exist naturally as molecules.
