Ionic, Covalent, Metallic Bonds
This happens to electrons in an ionic bond.
What is electrons are transferred from one atom to another to form bond?
Matter cannot be created or destroyed in a chemical reaction.
What is the Law of Conservation of Mass?
This is the standard SI unit for length
What is a Meter?
This is a proposed tentative explanation for a reaction.
What is a hypothesis?
This is how a the chemical symbol for Iron is written.
What is a Fe?
These bonds form a lattice of positive metal ions surrounded by a sea of electrons allowing the electrons to move freely throughout entire structure and easily do this.
What are metallic bonds that are able to carry an elecrtic current?
Identify the reaction type:
2KlO3 --> 2KCl + 3O2
What is a decomposition reaction?
An object has a density of 2.7g/cm3 and a volume of 20 cm3. What is the mass of the object.
What is 54 grams?
(mass = volume x density)
In an experiment, this is intentionally changed or manipulated.
What is the independent variable.
These small numbers down the side of an element block indicate this.
What is the number of electrons in each orbital?
This type of bond is formed when electrons are transferred between atoms, typically between a metal and a nonmetal
What is an ionic bond?
In a chemical reaction these symbols each represent something in the reaction - s, l, g, aq.
What are solid, liquid gas, and aqueous?
Object A has measurements of 59cm x 40cm. What is the area of the object.
What is 2360cm2
This factor in an experiment is measured or observed to see how it responds to changes.
What is the dependent variable?
This is indicated by the column placement of an element.
What is the number of electrons in the outer orbital? or What are the properties of the elements?
These are the electrons in the highest occupied energy level of an atom, responsible for all chemical bonding.
What are valence electrons?
This law requires that all chemical equations are balanced.
What is the Law of Conservation of Mass?
What is the measurement in centimeters of line that is 24m long.
What is 2400 centimeters?
Identical plants grown under the exact same conditions but are given water instead of fertilizer.
What is the control group?
The name of the horizontal rows that go across a periodic table.
What is a period?
This is the name for the compound NaCl.
What is Sodium Chloride?
What type of reaction is represented below
C3H8 + 5O2 --> 3CO2 + 4H2O
What is a combustion reaction?
Ball is placed in a graduated cylinder with a water level of 15cm. What is the volume of the ball if the water rose to 25cm.
What is 10 cm3?
The facts, figures, and other evidence gathered through observation.
What is data?
This group, also known as Group 18, is known for being completely unreactive.
What are the Noble Gases?
