Write complete nuclear equations for the following processes.
Isotopes and nuclear chemistry worksheet. Isotope mass number of protons of neutrons of electrons strontium 90 90 38 52 38 222rn 222 86136 exercise 1. Write the atomic symbols for each isotope mass number two isotopes of gallium one having 37 neutrons and the other having 39 neutrons. The simplest example of an atom with different isotopes is hydrogen.
Atoms of a given element which have the same number of protons but different numbers of neutrons are called isotopes. The proper way to notate an isotope is to use the element s name or symbol with a dash and the element s mass number. Charger applicable x element symbol see periodic table atomic number 2 a cation with a charge of 3 containing 13 protons and 14 neutrons.
An anion with a charge of 1 containing 53 protons and 74 neutrons 2. For example the atomic mass of carbon is reported as 12 011 amu. Argon 40 is bombarded with a proton.
Nuclear chemistry practice worksheet key exercise 1. Isotopes and nuclear chemistry worksheet chemistry 2a name section 1. The chapter on atoms molecules and ions introduced the basic idea of nuclear structure that the nucleus of an atom is composed of protons and with the exception of ce 1 1h neutrons.
U 235 u 236 and u 238 refer to three isotopes of uranium with mass numbers of 235 236 and 238. Containment on site storage and off site disposal remember that every radioactive substance has a half life some only a few months others hundreds of thousands of years. Chemistry chemistry quizzes.
Uranium 234 is produced when a radioactive isotope undergoes alpha decay. Nuclear chemistry an introduction. Isotopes are nearly identical and have the same number of protons e g.
Complete the following table. C 12 c 13 and c 14. Abundance of isotopes h worksheet 4 3 keg 20m name the atomic mass for each element is reported on the periodic table.
For the following quiz you will need a periodic table. A nuclear nomenclature can be adopted to describe an specific nucleus that explicitly indicates both a and z. Thus isotopes have the same position in the periodic table the same chemical properties and the same atomic charge.
This number is a weighted average of the masses of each of the isotopes of an element. Cobalt 60 is produced when a radioactive isotope undergoes beta decay. As the number of neutrons increase in the isotope the nuclear charge a increases b decreases c remains the same.
Nuclear chemistry is the study of reactions that involve changes in nuclear structure. The inhalation of radon 222 and its decay to form other isotopes poses a health hazard. Carbon is composed primarily of two isotopes.
Identify the unknown element in each to complete the following nuclear equations. 13 an atom with 29 protons and 36 neutrons is an isotope of a si b cu c kr d cl 14 carbon exists as three naturally occurring isotopes. Select the best answer to the question.
