100
This is what is shown with a Lewis Dot Diagram
What are valence electrons?
100
True or False: A solid ionic compound can conduct electricity.
What is false?
100
In a covalent bond, atoms do this with their electrons.
What is share?
100
Any atom or group of atoms that is electrically charged.
What is an ion
100
Which would make a better central atom in a molecular compound- carbon or chlorine?
What is carbon?
200
These are the subatomic particles that are involved in bonding.
What are electrons (or more specifically valence electrons)?
200
This is the charge of an ion that formed by giving away an electron.
What is positive?
200
True or False: You can easily mix polar and non-polar compounds
What is false
200
This is the bond that forms between two oppositely charged ions.
What is an ionic bond?
200
Ionic bonds typically occur between these two types of elements.
What are metals and non-metals?
300
These two elements are content filling their outer shell with just two electrons.
What are hydrogen and helium?
300
Fluorine is in group 17. What is the charge on a fluoride ion?
What is 1-?
300
This is a compound whose atoms are covalently bonded.
What is a molecular compound.
300
This is the type of bond that forms when two atoms share two pairs of electrons.
What is a double bond?
300
This bond is very strong and causes compounds to have high melting points.
What is an ionic bond?
400
This is the rule that states that atoms tend to gain, lose, or share electrons in order to have 8 electrons in their outer shell.
What is the octet rule?
400
In ionic compounds, every ion is attracted to all ions near it that have an opposite charge. This gives ionic compounds this orderly shape.
What is a crystal shape.
400
When electrons are unequally shared, the atom that pulls more strongly will develop a slight _______________ charge.
What is negative?
400
In this type of covalent bond, the electrons are not equally shared.
What is a polar bond?
400
This is what the "sea of electrons" surround in a metallic bond.
What is positively charged metal ions?
500
Based on the Lewis Dot diagram, how many covalent bonds can an element in group 15 make?
What is 3?
500
This is the chemical formula for sodium oxide. (sodium is in group 1, oxygen is in group 16)
What is Na2O?
500
If two polar bonds balance each other out, the molecule as a whole will be this.
What is non-polar?
500
This is an ion that is made up of more than one atom.
What is a polyatomic ion?
500
This is the overall charge on an ionic compound
What is neutral or no charge?
