The nucleus of 6 Li is a powerful absorber of neutrons. It exists in the naturally occurring metal to the extent of 7.5$\%$ . In the era of nuclear deterrence, large quantities of lithium were processed to remove 6 Li for use in hydrogen bomb production. The lithium metal remaining after removal of 6 Li was sold on the market. (a) What are the compositions of the nuclei of 6 Li and 7 Li? (b) The atomic masses of 6 Li and 7 Li are 6.015122 and 7.016004 amu, respectively. A sample of lithium depleted in the lighter isotope was found on analysis to contain 1.442$\%$ 6 Li. What is the average atomic weight of this sample of the metal?
Gallium (Ga) consists of two naturally occurring isotopes with masses of 68.926 and 70.925 amu. (a) How many protons and neutrons are in the nucleus of each isotope? Write
the complete atomic symbol for each, showing the atomic number and mass number. (b) The average atomic mass of Ga is 69.72 amu. Calculate the abundance of each isotope.
guys Region Chapter two Problem 92. Chemistry of central signs. So they want to identify the element represent by each of falling symbols and give member of protons and neutrons and each. So let's hear what the number of protons and neutrons. So as so the protons are always a number on the bottom of the in these kind of scenarios. So we have 33 protons, 53 protons, 63 protons and a three pro tennis now for neutrons. If the's top number, the math number and we subtract that number of protons. So this one is going to be 40 41 neutrons. This one is going to be 74 neutrons, and this one's going to be 89 neutrons, and this one is going to be 126 neutrons. So let's look at which elements that we're dealing with. So which element has 33 protons? That is going to be arsenic. The gentleman has 53 protons That is going to be iodine. Gentlemen, it has 63 new 63 protons that is going to be European, and you and which element has 89 83 protons. That's going to be business
