Why is platinum give the atomic number 78?
Platinum is a non metal element. Atomic number of it is 78.
What is the complete symbol of an element that has 78 electrons and 117 neutrons?
Assuming this is an atom, 78 electrons means there are 78 protons, so this is platinum. The mass number will be 78 + 117 = 195 so the complete symbol will be 195/78 Pt where I've used the / to represent that 195 is a superscript and 78 is a subscript.
This is the element Platinum. How many neutrons does Platinum have?
Platinum has an atomic number of 78, which means it has 78 protons. The most common isotope of platinum, Platinum-195, has 117 neutrons. To find the number of neutrons in an isotope, you subtract the atomic number from the mass number; thus, Platinum-195 has 195 - 78 = 117 neutrons.
