How many protons, neutrons, and electrons does zinc have?
Zinc-64 is composed of 30 protons, 34 neutrons , and 30 electrons. Zinc-66 is composed of 30 protons, 36 neutrons, and 30 electrons. Zinc-67 is composed of 30 protons, 37 neutrons, and 30 electrons. Zinc-68 is composed of 30 protons, 38 neutrons, and 30 electrons.
What element has ten neutrons?
The number of neutrons corresponding to the most common isotope of the element is in bold type. All beryllium atoms have 5 neutrons in the nucleus and all fluorine atoms have 10 neutrons.
How many unpaired electrons in zinc?
There are no unpaired electrons in Zinc. Zinc is unusually stable because of the lack of unpaired electrons. Steel nails are often coated with zinc to keep the nails from rusting, because zinc is relatively unreactive.
How do you find the number of neutrons?
Subtract the atomic number from the atomic mass. Since the vast majority of an atom ’s mass is made up of its protons and neutrons, subtracting the number of protons (i.e. the atomic number) from the atomic mass will give you the calculated number of neutrons in the atom.
