Final Jeopardy Final Jeopardy Category: Holding onto Electrons

With every added primary level of electrons, it becomes harder for protons to hold onto electrons because of this. Final Jeopardy What is the shielding effect?

$800 What is an f-sublevel --or— What are 2 electrons in the highest s sublevel? This is what tungsten has but chromium and molybdenum do not?

$1000 What is sublevel 5d? Elements cerium through lutetium (atomic numbers 58 through 71) only have one electron in this sublevel.

$200 This is the fraction of mass that an electron (or beta particle) has compared to that of an alpha particle. What is th ?

$400 What are opposite spins? --or-- What is that the magnetic fields cancel each other? This is why 2 electrons can occupy the same orbital.

$600 What are which orbital an electron is in and what it’s direction of spin is? This is what 2 things orbital notation can tell you about electrons that electron configurations cannot.

$800 What is the electron cloud? This is where chemical reactions take place.

Electron configurations, orbital notations, and quantum numbers are only written for these kinds of electrons. $1000 What are electrons in their ground state?

$800 What is zero? This is the atomic number of a neutron.

$1000 What is fission? This what splitting an atomic nucleus is called.

$200 What is a mass of zero? This is how the mass of this particle, β, is treated when balancing nuclear reactions.

$400 What is deuterium? Besides hydrogen-2, this is another name for this particle:.

$600 What is gamma radiation? This form of radiation has no mass and no atomic number.

$800 What is an alpha radiation? This form of radiation is made of particles that are essentially the nucleus of a helium atom.

$1000 What is an alpha particle? This nuclear particle is so weak that it cannot even penetrate a piece of paper.

$800 What are radioisotopes? This is the name that we give to isotopes that are unstable.

$1200 What is carbon 14? This the isotope of carbon that goes through beta decay.

$1600 What is 20? The “band of stability” follows the p + = n line until you reach the element with this proton number.

$400 What is 1/8 th of the original radioisotope? This is how much of a radioisotope is left after 3 half lives.

$800 What is a high specific activity? Radioisotopes that decay rapidly are said to have this.

It’s the ratio of these 2 isotopes that tells scientists how long ago something died. $1200 What are carbon-14 and carbon-12?
