Why Chemical Bonds Form
100
This is formed when atoms share or transfer electrons.
What is a chemical bond?
100
Molecules are represented by these.
What are chemical formulas?
100
The properties of a compound depend more on these than on the elements.
What are structure and composition?
100
Not all compounds are made of these.
What are molecules?
100
This is released when a chemical bond is formed.
What is energy?
200
This molecule shares electrons between hydrogen and oxygen.
What is water?
200
A chemical formula tells you this about each molecule.
What is number and each kind of atom?
200
The ________________ of elements was changed resulting in a different properties.
What is ratio?
200
Atoms do this to become ionic.
What is gain or lose an electron?
200
Atoms form compounds because atoms of a __________ level of energy when they are together in compounds.
What is lower?
300
This type of bond is formed when atoms share electrons.
What is a covalent bond?
300
This tells you the number of each kind of atom in a molecule.
What is the subscript?
300
Because of this, compounds can have the same chemical formula but be different compounds.
What is structure?
300
This type of bond transfers an electron from one atom to another.
What is ionic bond?
300
Only these do not form chemical bonds.
What are noble gasses?
400
This is a group of atoms held together by covalent bonds.
What is a molecule?
400
Lines are used to represent double and triple these.
What are bonds?
400
These 2 molecules have the same elements but not the same properties.
What is asprin and plastic wrap?
400
Ionic compounds do not form this.
What are molecules?
400
Reactive means this.
What is an element readily forms chemical bonds.
500
This bond involves 3 electrons per atom.
What is a triple covalent bond?
500
Real molecules are not flat. They are ______________
What is three dimensional?
500
Both of these determine the properties of a compound.
What is chemical formula and structure?
500
Ionic compounds may transfer or more of these.
What are electrons?
500
The _____________ an element is to a noble gas, the _______ reactive it is.
What is closer and more?
