Energy and Chemical Reactions
100
Any charged particle that has an extra electron or an extra proton.
What is an Ion?
100
This occurs when two electrons are shared between 2 elements.
What is a Covalent Bond?
100
The atomic number equals the number of these in an atom of that element.
What is ?the number of Protons
100
In this type of reaction, one reactant is not in a compound and another reactant is in a compound. In the product, the single reactant is now in a compound and the other product is by itself, not in a compound. AB + C --> AC + B
What is a Single Replacement reaction?
100
In any reaction, these are broken in the reactants and reformed in the products
What are chemical bonds?
200
When writing chemical names, the second chemical, which is the anion always ends in this.
What is an "ide"?
200
This is the name of a specific type of covalent bond when the 2 electrons are not shared equally making 1 side of the molecule more (+) and 1 side of the molecule more (-).
What is Polar or Polar Covalent?
200
Is the number of protons equal to the number of electrons in an element as it exists in nature/if not in a bond.
What is Yes?
200
In this type of equation, two molecules in the reactants come together to form one product.
What is Synthesis reactions?
200
The Energy within molecules is in these.
What is the bonds?
300
In chemical equations, a subscript number (lower) describes what.
What is number of atoms of the element just to the left of that subscript?
300
This type of bond is more strong than an Ionic Bond?
What is a Covalent Bond?
300
The Group number is this/ represents this in all the elements in that column.
What is number of electrons in the valence level (how many electrons are in the outer ring)?
300
In this type of reaction, one reactant is split to form one or more products.
What is a Decomposition reaction?
300
No matter what type of reaction occurs, the amount of this always is the same in the reactants and the products.
What is Matter or Energy?
400
When one electron moves to another element this type of bond is formed.
What is an Ionic bond?
400
In regular covalent bonds, one of the atoms becomes (+) and one of the atoms becomes (-) because only 1 electrons moves over. True of False
What is False? In covalent bonds, 2 electrons are shared equally. and no element becomes and ion (+ or -)
400
Once you know how many electrons are in the valence ring, this is where the other electrons of the atom go.
What is the inner ring?
400
In this type of reaction, 2 components of 2 reactant molecules switch places to form 2 different products.
What is double replacement reaction?
400
The energy in this type of reaction is greater in the reactants than in the products and energy is released.
What is Exothermic?
500
This word describes a positive (+) ion.
What is Cation?
500
When elements bond, the electrons in the valence ring are the ones that form the bonds. True or False
What is TRUE
500
These subatomic particles are drawn in the ring configuration for atoms of an element.--(protons, neutrons, electrons)
What is electrons?
500
In this type of reaction, CO2 and H2O are always formed.
What is a Combustion reaction?
500
The energy in this type of reaction is less in the reactants and greater in the products and energy is absorbed into the products.
What is Endothermic?
