Table N - Radioisotopes
This isotope of an alkaline earth metal has a half life of 182 milliseconds.
What is Ca-37 ?
This particle in Table O has the most mass.
What is an alpha particle?
What is 1/4th?
This isotope is used for treating thyroid disorders.
What is iodine-131 ?
What is 18 grams per mole?
This isotope of an alkali metal on Table N undergoes positron decay.
What is K-37 ?
This particle from Table O has no mass and no charge.
What is gamma radiation?
If substance "X" has a half life of 3 years, this is the fraction would remain after 9 years.
What is 1/8th ?
This is when one larger nuclear splits into two or more smaller nuclei.
What is nuclear fission?
What is empty space?
This isotope from Table N has the longest half life period.
What is U-238 ?
This particle from Table O has the most penetrating power.
What is gamma radiation?
This is the fraction of the original sample of K-37 that remains after 2.46 seconds.
What is 1/4th?
This isotope is used to treat cancer.
What is cobalt-60 ?
In this type of bonding, nonmetal atoms share electrons equally. In other words, they have an equal distribution of electron density.
What is nonpolar covalent bonding?
Strontium-90 has a half life of this many decades.
This particle from Table O has no mass, but does have a positive charge.
What is a positron?
This is the mass remaining after 90.6 years of a sample of Cs-137 that was initially 80 grams.
What is 10 grams?
Which of the following is an artificial transmutation?
90Sr --> 90Y + beta particle
37K + alpha particle --> 41Sc
53Fe --> 52Fe + neutron
K-37 (it's a bombardment!)
Is the following reaction spontaneous or not? And you MUST provide evidence as to why you think so:
Mg(s) + Fe+2 --> Mg+2 + Fe(s)
YES - since magnesium is oxidized AND it is higher up on Table J than iron.
N-16 has a half life of this many years.
What is 2.26x10^-7 years?
This particle from Table O has the most ionizing power.
What is an alpha particle?
This is the mass remaining after 2.8x109 years of an initially 200 gram sample of U-235.
What is 12.5 grams?
State one major advantage and one major disadvantage of nuclear energy.
ADVANTAGE: Huge amounts of energy that - when contained - releases only water vapor.
DISADVANTAGE: Waste and/or spills cause massive contamination
What is the volume of a 50.0 gram sample of tungsten?
What is 2.59 cm3 ?
