How many neutrons does platinium have?

Answer 1

Platinum has 6 naturally occurring isotopes, all of which have 78 protons. The number of neutrons can vary, but the most common isotopes have between 116 and 118 neutrons. The full list of isotopes is:

• 190Pt (78 protons and 112 neutrons)
• 192Pt (78 protons and 114 neutrons)
• 194Pt (78 protons and 116 neutrons) about 1/3 of all platinum
• 195Pt (78 protons and 117 neutrons) about 1/3 of all platinum
• 196Pt (78 protons and 118 neutrons) about 1/4 of all platinum
• 198Pt (78 protons and 120 neutrons) about 1/14 of all platinum

Answer 2

Platinum has five stable isotopes, 192Pt, 194Pt, 195Pt, 196Pt, and 198Pt, with 114, 116, 117, 118, and 120 neutrons, respectively. In addition, there is one naturally occurring radioactive isotope, 190Pt, which has 112 neutrons. There are a number of synthetic isotopes, with numbers of neutrons ranging from 88 to 134, and isotopic numbers from 166 to 202.

Answer 3

Platinum's atomic number is 78. It's three most common isotopes are 194Pt, 195Pt, and 196Pt. They have 116, 117, and 118 neutrons, respectively.

Answer 4

Platinum typically has 117 neutrons in its nucleus, although isotopes of platinum with varying numbers of neutrons do exist.

Answer 5

117
