Define cation?
an ion with a positive charge
_____ bonds transfer electrons, have strong bonds, & are between metals & non-metals?
Ionic
____ bonds share electrons, have weak bonds, & are between non-metals & non-metals?
Covalent
____ bonds are strong and are between the cations & the surrounding valence electrons. These valence electrons have great mobility. They are between metals.
Metallic
____ bonds are between more than two different elements?
Polyatomic
When naming ionic bonds which one goes first - cation or the anion?
Cation
What is the processes for naming an ionic compound?
Cation then anion, no prefixes, change the last syllable of anion to -IDE
What is the process for nami g covalent compounds?
Most metallic one to the left goes first, use prefixes (1- mono / 2-di / 3-tri / 4-tetra/ 5-penta), no mono on the first word, change last syllable of 2nd word to IDE
