Subatomic Particles
This negatively charged subatomic particle orbits the nucleus in specific energy levels.
What is an electron?
This value on the periodic table is equal to the number of protons in an atom's nucleus.
What is the atomic number?
Boasting an atomic number of 1, this is the lightest, simplest, and most abundant element in the universe.
What is Hydrogen?
This term describes how close a single measurement is to the true, accepted, or target value.
What is accuracy?
This Boyle's law states that if you decrease the volume of a gas, this specific property will go up.
What is pressure?
Possessing a neutral charge, this particle resides in the nucleus and acts as the "glue" holding it together.
What is a neutron?
To find the number of neutrons in an atom, you subtract the atomic number from this total value
What is the atomic mass (or mass number)?
This non-reactive, noble gas has 2 protons, 2 neutrons, and is famous for making balloons float.
What is Helium?
This term describes how close a series of measurements are to each other, regardless of whether they hit the target.
What is precision?
According to this fundamental law, matter cannot be created or destroyed in a chemical reaction, only rearranged.
What is the Law of Conservation of Mass?
This positively charged particle determines the identity of an element.
What is a proton?
If a neutral carbon atom has an atomic number of 6, it must contain this many electrons.
What is 6?
A neutral atom of Lithium has an atomic number of 3. It possesses this exact number of protons and electrons.
What is 3?
If a scientist throws three darts and they all hit the exact center bullseye, their results are said to have both of these qualities.
What are accuracy and precision?
This gas law states that the volume of a gas is directly proportional to its temperature in Kelvin.
What is Charles's Law?
Found in the dense center of the atom, these two specific subatomic particles make up the vast majority of an atom's mass.
What are protons and neutrons?
A neutral atom of Lithium-7 has an atomic number of 3. This is the exact number of neutrons hiding in its nucleus.
What is 4?
Atoms of the same element that have the same number of protons but different numbers of neutrons (and therefore different atomic masses) are known by this term.
What are isotopes?
If a digital scale consistently reads 5.0 grams every time you weigh a 10.0-gram weight, the scale is high in this quality, but low in another.
What is high precision and low accuracy?
Named after a French chemist, this law states that if you heat a gas in a rigid container, its pressure will increase.
What is Gay-Lussac's Law?
