Molecular & Ionic Compounds
This type of chemical compound forms when a metal transfers electrons to a nonmetal.
What is an ionic compound?
These group 1 metals are so reactive with water that they have to be stored in oil, and they all have just 1 valence electron
What are alkali metals?
Instead of transferring electrons, atoms in this type of bond share pairs of electrons so each can both get a full outer shell.
What is a covalent (or molecular) bond?
Found in Group 17, this family of nonmetals includes fluorine and chlorine, and they love to react with metals to make salts
What are halogens?
These are the specific electrons located in the outermost shell of an atom that are directly involved in forming chemical bonds.
What are Valence electrons?
Elements like magnesium and calcium belong to this group 2 family, which forms +2 ions when they react
What are alkaline earth metals?
These groups of nonmetal atoms join together to carry an overall positive or negative charge, like nitrate or sulfate.
What are polyatomic ions?
These group 18 gases are completely unreactive and "loners" because their outer valence shells are already full
Solid salt won't do it, but dissolving an ionic compound in water allows the separated ions to move freely and do this action.
What is conduct electricity?
These elements sit right on the zigzag staircase line of the periodic table, showing a mix of both metal and nonmetal properties
What are metalloids?
