Atomic structure 1
These are the 2 parts of an atom.
What are the nucleus and the electron cloud?
This is the charge of a proton.
What is (+) positive?
This type of radioactive decay releases a helium nucleus containing 2 protons and 2 neutrons.
What is alpha decay?
This is the formula to figure out the # of neutrons an isotope contains.
What is the atomic mass - protons?
This process occurs when a large atomic nucleus splits into two smaller nuclei and releases energy?
What is nuclear fission?
This piece of safety equipment should be worn whenever chemicals, heat, or glassware are being used in the laboratory.
What are safety goggles?
These are the 3 subatomic particles that make up an atom.
What are protons, neutrons, and electrons?
This is the charge of an electron.
What is (-)negative?
almost no mass
This type of decay releases a high-energy electron from the nucleus.
What is beta decay?
This is the number in the superscript of isotopic notation.
What is mass number/atomic mass (protons + neutrons)?
This process occurs when two small atomic nuclei combine to form a larger nucleus and release a tremendous amount of energy.
What is nuclear fusion?
If a chemical splashes into your eyes, you should immediately use this piece of emergency equipment and flush your eyes with water.
What is an eyewash station?
These are particle(s) found in the nucleus.
What are protons and neutrons?
This is what you use to name an isotope.
What is mass number/atomic mass?
Unlike alpha and beta radiation, this type of radiation is a high-energy electromagnetic wave and has no mass or charge.
What is gamma radiation?
This is the number in the subscript of isotopic notation.
What is atomic number/number of protons?
In a nuclear fission reaction, this particle is commonly fired at a large nucleus to cause it to become unstable and split.
What is a neutron?
Students with long hair should do this before beginning a laboratory activity to prevent their hair from catching fire or coming into contact with chemicals.
What is tie your hair back?
This subatomic particle determines the element of an atom
What are protons?
This is the subatomic particle never changes unless it undergoes beta decay.
What are protons?
Rank these three types of radiation from least penetrating to most penetrating: alpha, beta, gamma.
What is alpha ā beta ā gamma?
This scientist used the Gold-Foil experiment and found that the nucleus was positively charged and is mostly empty space?
What is Ernest Rutherford?
The Sun produces its energy primarily through this nuclear process, in which hydrogen nuclei combine to form helium.
What is nuclear fusion?
A student spills a small amount of acid on the laboratory table. The student should NOT simply wipe it up with a paper towel. The first step should be to ________.
What is notify the teacher?
How many electrons can fit on first energy level?
What is 2?
This is what a Bohr model of a neutral Helium-4 isotope atom would look like (describe all particles)
What would 2 protons, 2 neutrons and 2 electrons be?
This is the correct isotope for the nuclear equation for this alpha decay:
23892Uā? _______+42He
What is 23490Th?
This is ONE difference and ONE similarity between carbon-12, carbon-13 and carbon-14.
A uranium-235 nucleus absorbs a neutron and splits into smaller nuclei, releasing additional neutrons. Those neutrons cause more uranium nuclei to split. This is called a ________ reaction.
What is a nuclear chain reaction?
This piece of laboratory equipment removes or controls hazardous chemical vapors, fumes, and gases from the air students breathe.
What is a fume hood?
