Don't Overreact
These are substances that undergo a chemical change
Reactants
This is an atom or group of atoms that has a positive or negative charge
ion
This is a force of attraction between atoms or a group of atoms due to the sharing or transferring of electrons
chemical bond
Elements that do not have a stable electron configuration with complete sets of these tend to be reactive.
valance electrons
These are new substances formed as a result of a chemical change
Products
Positive Ions are called this
cation
this is a chemical bond formed between oppositely charged ions
ionic bond
The most stable electron configuration for atoms is when this has a full set of electrons
highest energy level
True or False: More than one product can be formed in a chemical change
True
anions
These bonds form between atoms of nonmentals when they share valence electrons
Covalent Bonds
This is the only element with the necessary properties for life
Carbon
In nature, oxygen only exists as this - which is composed of 2 oxygen atoms bonded together
Follow these steps to name cations
element name + the word ion
Ionic compounds are formed between cations and this
anions
This is a model of an atom in which each dot represents a valence electron
electron dot diagram
An equation is balanced when it has the same number of these of each element on both sides of the equation
atoms
Follow theses steps to name anions
Use the first part of the element name + the suffix ide
Elements of the alkali metals form ionic compounds with elements of this family
halogen
This model for a molecule or compound shows the bonds between atoms by dashes
structural formula model
