What is the mass number for a sulfur atom that contains 31 neutrons?
The mass number is calculated by adding together the number of protons and neutrons in an atom. A sulfur atom typically has 16 protons, so if it contains 31 neutrons, the mass number would be 16 (protons) + 31 (neutrons) = 47.
What is the mass number of the isotope with the symbol 3717Cl?
The mass number of an isotope is the sum of protons and neutrons in its nucleus. In this case, the symbol 37 refers to the total number of protons and neutrons, which means the mass number of the isotope 37-17Cl is 37.
How many protons in a isotope of sodium with a mass number of 20?
All atoms of sodium contain 11 protons, since 11 is the atomic number of sodium.
Which isotope contains the greatest number of protons?
Atomic number is a measure of protons and electrons. extra or less Neutrons are what make an isotope and are not included in atomic number. therefore element with the highest atomic number will also be the isotope with the highest atomic number. on my periodic table it is lawrencium at 103. (note although this might have extra neutrons making it an isotope, it will always have the same atomic number - atomic number isn't what determines an isotope it is mass number) if you meant mass number (which is what determines an isotope), you can subtract the atomic number from the mass number to find out how many neutrons there are and determine whether it is an isotope or not
What is the mass number of an iron isotope with 26 protons 31 neutrons ans 24 electrons?
Number of protons + neutrons = mass number 26 protons + 31 neutrons 57
How does the atomic number relate to the number of protons in an atom?
Atomic Mass (of an isotope) - number of protons (of an isotope) = number of neutrons (of an isotope)
An isotope of chlorine has 25 protons and 17 neutrons what is the mass number of that isotope of chlorine?
The mass number of an isotope is the sum of its protons and neutrons. In this case, the isotope of chlorine has 25 protons and 17 neutrons. Therefore, the mass number is 25 + 17 = 42. Thus, the mass number of this isotope of chlorine is 42.
What is the mass number of an oxygen isotope that has nine neutrons?
The mass number of an isotope is the sum of its protons and neutrons. For oxygen, which has 8 protons, an isotope with nine neutrons would have a mass number of 8 (protons) + 9 (neutrons) = 17. Therefore, the mass number of this oxygen isotope is 17. This isotope is known as oxygen-17.
What contains promethium?
The atom of promethium contain 61 protons and electrons.For each isotope the number of neutrons is different. Number of neutrons = Mass number of an isotope - 61
What is the nucleus of an isotope with a certain atomic mass and number?
The nucleus of an isotope with a specific atomic mass and number contains protons and neutrons. The number of protons determines the element, while the sum of protons and neutrons gives the atomic mass. The neutrons in the nucleus help stabilize it by balancing the repulsion between positively charged protons.
An isotope of radon has 86 protons and 137 neutrons what is the mass number of this isotopes?
An isotope of indium has 77 protons and 115 neutrons. What is the mass number of this isotope
What is the mass number of an oxygen isotope that has 9 neutrons?
The mass number of an isotope is the sum of its protons and neutrons. Oxygen has an atomic number of 8, meaning it has 8 protons. If the isotope has 9 neutrons, the mass number would be 8 protons + 9 neutrons = 17. Therefore, the mass number of this oxygen isotope is 17.
A common isotope of carbon has a mass number of 13 The total number of protons and neutrons in the nucleus is?
13. The mass number is always the total number of protons and neutrons.
An isotope of iron has 26 protons and 32 neutrons what is the mass number?
An unknown element contains 24 protons, 21 electrons,and has mass number 54
What is the mass number of an isotope of Ca with 24 neutrons?
The mass number of an isotope is the sum of its protons and neutrons. Calcium (Ca) has an atomic number of 20, meaning it has 20 protons. If the isotope has 24 neutrons, the mass number would be 20 protons + 24 neutrons = 44. Therefore, the mass number of this calcium isotope is 44.
If an isotope of silicon has 15 neutrons what is the mass number?
The mass number of an isotope is the sum of its protons and neutrons. Silicon has an atomic number of 14, meaning it has 14 protons. If the isotope has 15 neutrons, the mass number would be 14 protons + 15 neutrons, which equals 29. Therefore, the mass number of the silicon isotope is 29.
An isotope of xenon has an atomic number of 54 and contains 77 neutrons. What is the mass number of the xenon isotope?
The atomic number of an element is the number of protons in its nucleus. Always. The mass number of an atom is the number of protons plus the number of neutrons in it. And that means an isotope of element 54 (xenon) that has 77 neutrons in its nucleus has a mass number of 54 + 77 or 131, and you'll have an atom of 131Xe. A link can be found below.
