Darmstadtium is an artificial element; no stable isotopes exist. From Wikipedia: "Eight different isotopes of darmstadtium have been reported with atomic masses 267, 269-271, 273, 277, 279, and 281, ..." The numbers are protons + neutrons. Subtract 110 (the atomic number for this element) to subtract the protons, and get the number of neutrons for the different isotopes. In other words, between 157 and 171, depending on the isotope.
There are 118 neutrons in the element gold.
there are 61 neutrons in a the element silver
Hydrogen has 0 neutrons
Sulfur has 16 neutrons. To find out how many neutrons an element has you subtract the atomic number of that element by the atomic mass. omg thank you so much
about 66 or 64
neutrons = 40 - 18 = 22
Neon has 10 protons and 9 neutrons.
