100
This is what ionic compounds usually contain besides + charged metal ions.
What is negatively charged non-metal ions?
100
This is a covalent bond. It includes two answers.
What is a chemical bond formed when atoms share electrons, and a bond between two non-metals?
100
This is a crystal.
What is a regular repeating arrangement of atoms, ions, and molecules?
100
These are the two elements that make up water.
What are hydrogen and oxygen?
100
This is how many electrons are in carbon's valence shell.
What is four?
200
This is how you describe a positive ion and a negative ion.
What is positive ions lose electrons and negative ions gain electrons?
200
This is why a water molecule is considered a covalent bond.
What is because oxygen has 6 electrons is its outer shell, and 2 hydrogen will complete its valence so it will be stable?
200
Water is an example of this type of crystal. Sodium is an example of this type of crystal, and diamonds are an example of this type of crystal.
What is water is a molecule crystal, sodium is an ion crystal, and diamonds are covalent crystals?
200
These are properties of metals.
What is shiny, thin, solid at room temperature, good conductor of heat and electricity, malleable, and ductile?
200
This is the number of dots in a Lewis dot diagram for the Group 18.
What is 8?
300
This is an ionic bond.
What is an electrical attraction between positively and negatively charged ions in an ionic compound?
300
Polymers are this type of bond.
What are covalent bonds?
300
Crystals have these properties.
What are brittle, solid and usually have a high melting point?
300
These are least likely to interact or bond with other atoms.
What are noble gases?
300
On the periodic table, this group tends to form positive ions.
What are metals or Group 1 and 2?
400
Potassium is in Group 1. This is the symbol for the potassium ion.
What is K+?
400
This is a type of synthetic polymer.
What is polyethylene?
400
This is a unit cell.
What are the smallest repeating patterns that show how the atoms, ions, and molecules are arranged in a crystal?
400
This is how many atoms of oxygen are in 3 molecules of MgSO4.
What is 12?
400
This is the difference between a single and double bond.
What is two electrons are shared in a single bond and four electrons are shared in a double bond?
500
This why NaCl is an ionic bond.
What is because Na in Group 1 (metal) loses an electron by transferring it to Cl in Group 17 (non-metal). The result is sodium chloride.
500
These are the small units that make up polymers.
What are monomers?
500
Quartz and snowflakes have this kind of pattern.
What is hexagonal?
500
This is how many atoms of hydrogen are in 5 molecules of C6H8O7.
What are 40?
500
This holds sodium chloride crystals together.
What are covalent bonds?
