Periodic Table
There are seven of these on the periodic table.
What is a period?
What are molecules?
Anything that has mass and takes up space.
What is matter?
This law states that matter can neither be created nor destroyed, only transformed.
What is the Law of Conservation of Matter?
The number of "blocks" on the periodic table.
What is four?
The father of the modern periodic table
Who is Dmitri Mendeleev?
This man claimed the atom was the smallest unit of measurement and could not be broken into smaller particles.
Who is Democritus?
When matter goes directly from a solid to a gas.
The relationship between wavelength and frequency is ________________ proportional.
What is inversely?
This four-letter verb is the proper technique to use when smelling anything in a chemistry lab.
Alkaline Earth metals all contain this charge.
What is +2?
Who is Schrodinger?
What are intrinsic properties?
The four rules of significant figures.
1. Any non-zero digit is significant
2. Any zero that is sandwiched between two non-zero digits is significant
3. Leading zeros (to the left of the first non-zero digit) are not significant.
4. Trailing zeros (to the right of the last non-zero digit) are significant ONLY when there is a decimal.
A method of conversion that involves multiplying fractions in a straight line.
What is dimensional analysis?
These two elements are the only ones that are naturally liquids at room temperature.
What are Mercury and Bromine?
________ have differing numbers of neutrons, while __________ have an unequal number of protons and electrons.
What are isotopes and ions?
(Must be in that order)
This type of property can only be observed or measured when an atom goes through a change in identity.
What is a chemical property?
Equal volumes of gases under identical temperature and pressure will contain equal numbers of particles (atoms, ions, molecules, electrons, etc.).
What is Avogardo's Law?
There are _______ total students in this class period, including seniors.
(Refer to teacher for answer)
This corner of the periodic table contains the elements with the largest atomic radius.
What is the bottom-left corner?
This is where the temperature and pressure of a substance cause it to exist in thermodynamic equilibrium between the three states of matter.
What is the triple point?
_________ refers to how closely a measured value agrees with the correct value, while _________ refers to how closely individual measurements agree with each other.
What are accuracy and precision?
(must be in that order)
