Chemical Bond Content Flashcards
What is the most likely product from a combustion reaction?
Carbon Dioxide and Water
When your car rusts the Iron in your car combines with Oxygen. What type of reaction is this?
Composition
Will Lithium and Neon react with each other? Explain why or why not.
No because Neon is a noble gas that has its outer shell of valence electrons full.
Will Magnesium and Chlorine form a bond with each other? Explain why or why not.
Yes. Magnesium is more stable if it loses 2 electrons, and Chlorine needs to gain an electron.
They should form MgCl2
How many dots should the following elements have around them in an electron dot diagram? Ar, Cl, Mg, O
Argon - 8, Cl - 7, Mg - 2, O - 6 This signifies the number of valence electrons and is equal to the column that they appear in on the periodic table. (ignoring the transition metals)
What type of bond is represented by two lines between two chemical symbols. i.e. C=C
A double covalent bond.
A double or triple bond is actually weaker than a single bond.
What is the difference between a covalent, and an ionic bond? Which one is generally stronger?
Covalently bonded atom share electrons. Ionically bonded atoms swap electrons. Covalent bods are stronger because of the sharing. Ionic bonds onle exist because of the opposite charges on the ions.
What does the subscript in a chemical formula mean?
The subscript show the number of atoms there is of the element that precedes the subscript.
Why would a neutral atom gain or lose an electron?
To become more stable, and obtain a lower energy state.
The chemical symbol in an electron dot diagram is used to represent what in an electron dot diagram?
The Nucleus
How does a molecule become polarized?
One atom in the molecule has more electrons surrounding it compared to the other atoms.
The substances that go in to a chemical reaction are called what?
Reactants
What forms as a result of an acid base reaction.
Water and a salt made of the remaining parts of the acid and base.
What happens during a redox reaction?
Electrons are swapped between atoms. One atom gains electrons and is reduced, the other atom loses electrons and is oxidized.
Where is energy stored when heat goes into a reaction?
In the chemical bonds in the molecules that are formed.
Energy cannot be created or destroyed.
