Chemical Bonding Flashcards
Atoms of elements in Group 0/8 of the periodic table are ______ & _______
stable & unreactive
Why do noble/inert gases exist as individual atoms?
because they have full outer electron shells/valence shells
Why are the atoms of all elements except for noble gases not stable?
because they do not have full valence shells
How do unstable atoms obtain full valence shells to become stable?
by bonding
Atoms with how many valence electrons form Cations?
1,2, or 3
Atoms with how many valence electrons form Anions?
5,6, or 7
How are molecules formed?
when non-metal atoms with 4,5,6,or 7 valence electrons bond with each other.
What are the 3 main types of chemical bonding?
Ionic Bonding, Covalent Bonding & Metallic Bonding
When does Ionic Bonding occur?
when a metal bonds with a nonmetal
When does Covalent Bonding occur?
when 2 or more nonmetals bond
When does Metallic Bonding occur?
this occurs withing metals
How are chemical compounds formed?
when elements bond by ionic or covalent bonding
