What isotope has a mass number of 71?
Please visit the Zinc element page for information specific to the chemical element of the periodic table.
How many neutrons are in gallium-71?
Gallium-71 is composed of 31 protons, 40 neutrons, and 31 electrons.
How do you find the mass number?
Together, the number of protons and the number of neutrons determine an element's mass number: mass number = protons + neutrons. If you want to calculate how many neutrons an atom has, you can simply subtract the number of protons, or atomic number, from the mass number.
How many neutrons are in gallium 70?
Diagram of the nuclear composition, electron configuration, chemical data, and valence orbitals of an atom of gallium-70 (atomic number: 31), an isotope of this element. The nucleus consists of 31 protons (red) and 39 neutrons (orange).
Why is the average atomic mass of gallium closer to 69 than it is to 71?
Also observe that the answer is closer to 69 than it is to 71, which makes sense since gallium-69 makes up a greater proportion of gallium in the universe ( ~60% ) than gallium-71 does ( ~30% ).
