Intro to Chemical Bonding

Cards (16)

Valence Electrons - The electrons in the outermost energy level that are involved in chemical bonding.
How can you tell how many valence electrons are in an element - Look at the group number (1&2) and subtract ten from the number for some (12-17)
Octet Rule - an atom will give away, take, or share their outer valence electrons to have their outer energy level with 8 electrons, or a "full" outer shell.
Chemical Bonding - The combining of elements to form new substances.
Three types of bonding - ionic, covalent, and metallic
Two types of compounds - ionic and covalent.
What are ionic compounds made up of - Metal cations and nonmetal anions
What are covalent compounds made up of - 2 or more nonmetals
What is ionic bonding - one atom "stealing" electrons from another
Ionic bonding occurs between what elements - a positive ion and a negative ion
What is a cation - a positive ion
What is an anion - a negative ion
What is covalent bonding - When electrons are shared by 2 or more atoms
Covalent bonding occurs between what elements - 2 or more nonmetals
How are electrons involved in covalent bonding - the valence electrons are shared
Metallic bonding occurs between what elements - 2 or more metals
