Bonding
This type of bond involves the SHARING of electrons
What is covalent?
The number of protons in an element. This is also how elements are ordered on the periodic table.
What is the atomic number?
Burning is a chemical reaction. Another word for burning is __________
What is Combustion?
The time it takes for radioactive material to reach 50% decayed
What is half-life?
Water is good at dissolving things because it is this type of molecule
What is polar?
This is a bond that occurs between metals and nonmetals
What is an ionic bond?
The number of protons and neutrons in an element.
What is the mass number?
The energy needed to start a chemical reaction
What is activation energy?
When one large nucleus splits into two or more smaller nuclei. This type of energy found in nuclear power plants.
What is nuclear fission?
A salt dissolved in water
What is an electrolyte?
This is a bond that occurs between nonmetals and nonmetals
What is a covalent bond?
What is group?
A chemical reaction when energy is ABSORBED. Energy is located on the left side of the chemical equation
What is an endothermic reaction?
List the THREE types of radioactive decay
What are Alpha Decay, Beta Decay, and Gamma Radiation?
Which has a greater amount of units? A mole of pennies or a mole of computers
TRICK QUESTION: They are the same amount of units! 6.02X 10^23
This type of bond occurs when electrons are TRANSFERRED from one element to another.
What is an ionic bond?
How many valence electrons does Carbon have?
Hint: The atomic number of Carbon is 6
What is 4?
This chemical reaction is reversible, meaning reactants form products and products can go back to reactants. This reaction has reached chemical _____________
What is equilibrium?
Fusion or fission: Which one requires the most energy?
What is fusion?
Write 3,980,000,000 in scientific notation
3.98 X 10^9
Atoms want to have this many valence electrons when bonding (also known as the octet rule)
What is eight?
List ALL six elements found on the periodic table that is necessary for life processes on Earth.
What are CHONPS?
Carbon
Hydrogen
Oxygen
Nitrogen
Phosphorus
Sulfur
H2 + O2 → H2O
Is this chemical reaction balanced? If not, how would you correct it?
2H2 + O2 → 2H2O
These radioactive elements have a different number of neutrons, which causes the mass number to change as a result. Cobalt-60 is an example.
What are isotopes?
Give me the correct formula for Magnesium Chloride.
Remember valence electrons and octet rule.
MgCl2
Mg wants to GIVE its two valence electrons. Cl can only take ONE each because it has 7 and can only hold 8. One Mg electron will go to one Cl atom and the other electron will go to a second Cl atom.
