Scientific Method
The first step of the scientific method.
What is determining the problem/asking a question by using qualitative and quantitative data?
The three parts of an atom.
What are protons, neutrons, and electrons?
Rows on the periodic table.
What are periods?
Bonds formed when electrons are shared between elements.
What are covalent bonds?
This is the first step in balancing any chemical equation.
What is to list and count the elements present on each side of the arrow?
Blue, rough, metal are all examples of what type of data.
What is qualitative?
The negatively charged particles of atoms.
What are electrons?
Describes the number of protons and electrons in an atom.
What is the atomic number?
The charge of a Magnesium ion.
What +2?
When balancing a chemical equation, you add these in front of the elements in order to increase the amount present.
What are coefficients?
The term we use to describe the manipulated variable or factor that the experimenter intentionally changes.
What is the independent variable?
The parts of the atom that are used to determine the atomic mass.
What are neutrons and protons?
The number of valence electrons required to have a full outer shell.
What is 8?
The strongest of the covalent bonds.
What is a triple bond?
The law of conservation of mass.
What is the mass of the reactants has to equal the mass of the products?
The final step of the scientific method.
What is developing a scientific theory or law?
The reason elements on the PT are neutral.
They have the same number of protons and electrons.
The number of neutrons in Barium (Ba).
What is 81?
The pair that would form an ionic bond.
Oxygen and chlorine
Nitrogen and sulfur

dependent: plant growth
The element with 76 protons.
What is Osmium (Os)?
The name of group 17 on the periodic table.
What are the Halogens?
