Valence Electrons Flashcards
What numbers does principle (n) go to?
1-7
How do you abbreviate electron configurations?
take last noble gas of period above
What is a compound?
2 or more atoms joined together by a bond
What are the 2 types of bonds?
ionic and covalent
What are ionic bonds?
attraction of charge ions
metal cation + nonmetal anion
What does attraction mean?
nonmetal takes electron from metal
What is a covalent bond?
sharing of electrons
occurs between two nonmetals
What does sharing mean?
nonmetals share electrons amongst each other
What are core electrons?
not involved in bonding
chemical reactions
What are valence electrons?
furthest from nucleus
involved in bonding and reactions
last row of electrons in configuration
What is the abbreviated (condensed) electron configuration?
replaces core electrons with nearest noble gas
