Alpha particles can be stopped by this substance
What is, "paper?"
100
This is what you call an atom that has gained or lost electrons

200
These are the two types of pure substances
What are elements and compounds
200
THIS is the definition of an isotope
What are, "Two or more atoms of the same element that have different masses?"
200
Using the Periodic Table, THIS indicates the number of protons and electrons in an atom?
What is "the atomic number?"
200
THIS is what constitutes an beta particle.
What is, an electron (that is ejected from a nucleus)
200
This is the charge of a halogen ion.
What is "1-?"
300
This is a drawing of the Bohr model for Phosphorous
see the board - 2 inner shell, 8 middle, 5 valence, 15 protons, 16 neutrons
300
This is the reason that some isotopes are unstable and undergo radioactive decay.
What is, the number of neutrons and protons in the nucleus are not balanced/do not have a stable ratio?
300
THIS is what you call the electrons in the outermost shell of an atom (based on the Bohr model)
What are valence electrons?
300
In beta decay, THIS happens to a neutron within an atom's nucleus
What is, it becomes a proton and an electron?
300
When naming ionic compounds, you say this portion first
What is, "the cation?"
400
THESE are three ways you know that a chemical change has taken place.
What are, "burning/smoking/releasing gas, change of color, change in mass, change in odor, formation of a precipitate, temperature change?" or "What is any change that cannot be reversed?"
400
When unstable isotopes undergo radioactive decay, they emit particles. These are the four particles that can be emitted during the process of radioactive decay.
What are, "alpha particles, beta particles, gamma particles, and neutrons"
400
THIS is the element found in Period 5 and Group 6 of the periodic table, and THIS is the family that it is in.
Molybdenum, transition meta.
400
In a nuclear power plant, what is the purpose of the uranium decay process?
To produce heat that will heat water to steam, turn a turbine and produce electricity.
400
