The study of the composition, structure, and properties of matter and the changes it undergoes.
What is chemistry?
100
A logical approach to solving problems by observing and collecting data, formulating hypotheses, testing hypotheses, and formulating theories that are supported by data.
What is the scientific method?
100
This is represented by a lambda, distance between corresponding points on adjacent waves.
What is wavelength?
100
Matter is neither destroyed nor created during ordinary chemical reactions or physical changes.
What is the law of conservation of mass?
100
A recurring pattern or event regarding the periodic table.
What is periodicity?
200
Branch of chemistry that studies non-carbon compounds.
What is inorganic chemistry?
200
The closeness of measurements to the correct or accepted value.
What is accuracy?
200
All forms of electromagnetic radiation are a part of this.
What is the electromagnetic spectrum?
200
Smallest part of an element still retaining its chemical properties.
What is an atom?
200
He standardized atomic weight among chemists.
Who is Cannizzario?
300
This type of change occurs when the identity of the substance remains the same.
What is a physical change?
300
Density = ? / Volume
What is mass?
300
The minimum quantity of energy lost or gained by an atom.
What is a quantum?
300
Number of protons in the nucleus of an atom.
What is atomic number?
300
Electronegativity increases moving right across the periodic table and decreases as you move down. Atomic Radii decreases as you move right and increases as you move down.
What are two examples of periodicity?
400
Groups are vertical columns that contain elements with similar chemical properties. Periods are horizontal rows which contain elements that tend to be more similar the closer they are in a period.
What is the difference between a group and a period?
400
Two quantities change in relation to each other keeping the answer constant.
What are inverse proportions?
400
Lowest energy state of an atom.
What is ground state?
400
Any isotope of any element.
What is a nuclide?
400
As you move right, electronegativity increases causing the electron cloud to be pulled closer to the positive nucleus.
Why do atomic radii decrease moving right across the periodic table?
500
A metal is a good conductor of heat and electricity, while a nonmetal has low conductivity. Most metals are solid at room temperature and are malleable. Most nonmetals are gases at room temperature, and the solids tend to be brittle.
What is the difference between metals and nonmetals?
