Ionic Bonding
What is an ion?
A negatively or positively charged atom with unequal protons and electrons
How many electrons are shared in a single bond?
What is 2 electrons?
What do the dots in the Lewis dot structure represent? (Be as specific as possible)
Valence electrons
The joining of atoms to from new substances.
What is a Chemical Bonding
What does the Periodic Table tells us the # of.
The number of protons, electrons, neutrons, and valance electrons.
What happens to valence electrons when an ionic bond is formed?
They are transferred from a metal to a non-metal.
Describe what happens to valence electrons when a covalent bond is formed.
When electrons are shared between two non-metal atoms?
Draw the Lewis Dot Structure for Carbon
C with 4 dots
The outermost layer of electrons.
What is Valance Electrons
What does bonding have to depend on?
It depends on the valance electrons or the outermost ring.
What is the difference between a cation and an anion?
Cations are positively charged and anions are negatively charged
In Covalent bonds, atoms tend to share their electrons with each other to do this
What is to satisfy the octet rule?
Draw the Lewis Dot Structure for Ca+2
Ca no dots
Pattern in which a crystal is arranged.
What is a Crystal Lattice.
How can you make a positive or negative ion?
You can gain and lose electrons.
Bromine is looking to receive how many electrons during an ionic bond?
One
Three pairs of shared electrons is called
What is a triple bond?
Draw the Lewis Dot Structure for krypton
Kr with 8 dots
The group that has a full outer shell
What are the noble gases?
Describe how the valance electrons in a metal move.
It moves in like a sea of electrons.
Are Ionic bonds melting points higher or lower than Covalent
Ionic Bonds have higher melting points.
Draw the Lewis Dot Structure for SiO2
O=Si=O with 4 dots on each O
