Balanced vs. Stable+ions
The overall charge of the atom is ZERO
What is a balanced charged atom
an atom that has lost electrons and now has a POSITIVE charge
What is a "cation"
Elements become this when they GAIN electrons.
When do elements become ANIONS
Shows the numbers of atoms of each element in the smallest representative unit of a substance.
What is a "Chemical formula"
more than one atom bonded together, making a compound with an overall charge.
What are Polyatomic Ions
The valence electron orbital is FULL.
What is a stable atom
An atom that has gained electrons and now has a NEGATIVE charge.
What is an "Anion"
Metals transfer electrons to nonmetals.(think opposites)(think neutral)
How are neutral compounds created?
Ionic compounds can conduct this when melted or dissolved in water.
When can Ionic compounds conduct an electric current?
has a charge of +2, written as Ca²⁺
What is the charge of a calcium ion?
Being stable is more important than being balanced/neutral!
What is more important to an atom
Dots are placed around the symbol of the element to indicate the valence electrons.
Why are Dots placed around the symbol of an element
Ends in “ide”. (negative metals)
What do nonmetals end in
The forces of attraction between the free-floating valence electrons and the positively charged METAL ions.
What are Metallic bonds
(Cl⁻) has 8 valence electrons
How many valence electrons does the ion of chlorine have?
Once the valence orbital holds 8 electrons, the atom is stable
What is the "Octet Rule"
Elements become this when they LOSE electrons.
When do elements become CATIONS
A compound composed of cations (metals) and anions (nonmetals).
What is an Ionic compound
mixtures of 2 or more elements, at least one of which is a metal.
What are Alloys
(Al) is typically a Cation
Does aluminum form a cation or an anion?
an atom (or group of atoms) that has gained or lost electrons, resulting in a negative or positive charge.
What is an ion
This structure is used to show the valence electrons of atoms.
What is "Electron Dot Structures"
Ionic compounds are held together.(bonds)
What are ionic bonds
Metals that have multiple charges. (The answer asks for the group type of metals that is mainly known for multiple charges)(think transition)
What are the charges of (transition metals)
(Li⁺) has 2 total electrons
How many total electrons does the ion of lithium have?
