Question 1 (4 points) Listen Fusion requires extremely high temperatures to begin because ()nuclei without neutrons can't create larger nuclei that DO contain neutrons O positive nuclei repel each other hydrogen and helium are gases O releasing more energy requires a greater input of energy firstQuestion 2 (4 points) Listen A nucleus of Plutonium-239 is bombarded with a neutron causing it to produce Xenon-134, Zirconium-103, and 3 neutrons. How would you write the isotopic notation for Xenon-134? O 54 134 Xe O Xenon - 134 O 134 55 O 134 54 KeQuestion 3 {4 points} E-ll A nucleus of Plutonium239 is bombarded with a neutron causing it to produce Xenon134, Zirconium103, and 3 neutrons. How would you write the isotopic notation for the neutron Question 4 [4 points] E 4:] Listen u Consider the following nuclear fusion reaction using Deuterium [HZJ and Tritium [H 3] as fuel: H+ fH >1He + _____ Which of the following products completes the equation? Question 5 [4 points) E-Il While unearthing ancient pottery in the Gobi Desert, an archaeologist discovers a pot containing a large amount of naturally radioactive Am ericium-241, which experiences alpha decay. The archaeologist needs to protect himself, but also doesn't want to overheat in the desert sun. In addition to a facemask, which of the following is the most appropriate safety precaution that the archaeologist should take to protect against the alpha particles without overheating? O Wear a thick lead lined suit and gloves 0 Wear a pair of normal leather gloves 0 Nothing can protect the archaeologist from the alpha particles 0 Wear an aluminum lined suit and gloves Question 6 (4 points) Listen Cesium has 37 isotopes, the most of any element on the periodic table. One of Cesium's most stable isotopes undergoes beta decay to form Barium-135. Which of the following is the correct isotopic notation for the original Cesium isotope before it decayed? O 55 C's 135 135 C's 55 137 C's 135 56 C's
