How many protons nuetrons and electrons are in an atom of xenon?
Xenon's, or Xe's, atomic number is 54. That means that, if it's electrically neutral, it always has 54 protons and 54 electrons. The number of neutrons in a xenon atom can differ, though, depending on the isotope. The most common isotope of xenon has 78 neutrons, but there are other isotopes with a different number of neutrons in them that are fairly common as well.
How many protons and neutrons does a carbon have?
6 protons. The number of neutrons varies, but the most common isotope has 6 neutrons.
Does there have to be the same number of protons and neutrons in the nucleus?
No. Even atoms of the same element will vary in the number of neutrons in their nucleus. For example, carbon (6 protons) has isotopes with 6, 7, and 8 neutrons. The most common isotope of hydrogen (1 proton) does not have any neutrons. While the most common isotopes of the lighter elements generally have the same number of protons and neutrons, heavier elements will have more neutrons than protons. For example the most common most stable isotope of uranium (92 protons) has 146 neutrons.
What are the most common Xenon Ion?
Xenon does not readily form an ion.
How many Nutrons does the element neptunium have?
Number of neutrons = Mass number of an isotope - 93The most common isotope has 144 neutrons.
What is the number of neutrons in the element sulfur?
The number of neutrons in an atom depends on the isotope. The most common sulfur isotope has 16. The average number of neutrons in an atom of sulfur is about 32.065.
What is the number of neutrons in an atom of the most common isotope of rubidium?
69
How many neutrons are present in Hg?
The number of neutrons in an atom of mercury depends on the isotope. The most common mercury isotope has 122. The average number of neutrons in an atom of mercury is about 120.
What is the mass number of the most common isotope of the element Xenon?
The sewyer was left open. End of story.
How many number neutrons magnesium?
A stable magnesium atom has 12, 13 or 14 neutrons. The atom with 12 neutrons is the most common one.
The atomic number of uranium is 92 and its atomic mass is 238.how many neutrons does the most common isotope of uranium have.?
The most common isotope of uranium is uranium-238 with 146 neutrons.
How many neutrons are there in calcium?
The most common isotope of calcium (40Ca) has 20 neutrons. You can find this out by subtracting the number of protons (atomic number, 20), from the total AMU's of 40. About 96% of calcium on Earth is calcium-40. Calcium also has eight other isotopes, 41Ca through 48Ca, five of which are radioactive. The second-most prevalent stable isotope is 44Ca which is about 2% of all calcium.
