Answer: 3 question All oxygen atoms have eight protons, and most have eight neutrons as well. The atomic mass of this isotope is 18. if you go to the periodic table, you see that Oxygen's atomic number is 8. for the atomic mass, we need to determine it. Show me the answer. Oxygen-16. The slighty greater mass of 18 O—12.5 percent more than 16 O—results in differentiation of the isotopes in … It has atomic number, Z of 8 since is found at number 8 on the periodic table. If your book is saying something different, it's wrong.----Also, B. and D. are the same thing. A. So having 8 neutrons would give the isotope an atomic mass of 16. It has 8 protons, 7 neutrons, and 8 electrons. This is a model of oxygen, because the nucleus (glass bowl) has eight protons. The abundance of one isotope (containing 8 neutrons) is 9 0 %. So for part A, O represents the element oxygen. Question: Part A The Magnesium Isotope With 13 Neutrons Express Your Answer As An Isotope. Having 10 electrons makes it an *ANION with a charge of -2* Among your choices, the correct answer is A. Oxygen-18 is a heavier isotope with 8 protons and 10 neutrons, while Oxygen-16 is a lighter isotope with 8 protons and 8 neutrons. #"A=8+10=18"# This oxygen isotope is oxygen-18. If we look at a Periodic Table, we can see that Oxygen in the 16th period, 2nd row, has this mass. The most common isotope of oxygen has 8 neutrons. During an ice age there is more Oxygen-18 in ocean water. Oxygen (O) is an element in the periodic table with an atomic number of 8. A Chemical Reaction Does Not Occur For This Question. An isotope of oxygen with an atomic mass of 18 would have two extra ____ - 18637292 The … It has an atomic number of eight and it'll have a mass number of eight. There are three isotopes of oxygen, each containing 8, 9, 1 0 neutrons respectively. Isotopes are forms of a chemical element that have the same atomic number but differ in mass. Oxygen-18 is a naturally-occuring, stable isotope and is commonly used is scientific studies as a tracer. It is the most common component of the earth's crust at 49%. Mass number, A= 8+8 = 16. B) 16. 0 ΑΣΦ ? If we have oxygen isotope with eight neutrons, then we will use the chemical symbol Oh, for oxygen. The element symbol for oxygen is O and its atomic number is 8. Which is the correct reference for this isotope? The isotope Oxygen-18 has the comparable variety of protons through fact the traditional atom of Oxygen-sixteen. 5 years ago. In the model shown, the round green marbles represent protons and the flat blue marbles represent neutrons. This isotope is noticeably lighter than oxygen-16, which has eight neutrons and is oxygen’s most natural abundant form (about 99.7 percent). Dec 27, 2013 - Oxygen Element Explained The Oxygen element is an essential part of life on Earth and also serves as an excellent example in the process of metal corrosion which will aid our understanding of … 8. In addition, at room temperature, oxygen's state is gaseous. (B) 12.5 One atom of the element... Boron has two stable isotopes with masses of... Give the nuclear symbol for the isotope of... Bromine has two naturally occurring isotopes. B. a) oxygen-18 contains 9 protons while oxygen-16 only contains 8 protons. Carbon atoms with 7 neutrons have an atomic mass of 13 (6 protons + 7 neutrons = 13). Plus the eight neutrons 16 for the next one. Isotopes are the same type of atom with different masses. Oxygen is in Period 2 of the Periodic Table because it … This is how all the isotipoes of the other parts were derived . O-16 is by far the most common isotope in nature, accounting for more than 99.8% of all oxygen atoms, and O-17 is exceedingly rare, but O-18 is abundant enough in nature to be â ¦ It has a mass of 15.994 914 619 56 u. Oxygen-16 is the most abundant isotope of oxygen and accounts for 99.762% of oxygen's natural abundance. A. oxygen-18 B. oxygen-10 …
