What element has number of proton of78?
The only element with 78 protons is platinum (Pt).
What is the number of protons for platinum?
Platinum is a metal element. Atomic mass of it is 195.08.
An element that is a precious metal with 78 protons?
Platinum.
How many protons are in an atom of a pure element?
Each chemical element has a specific number of protons; the number of protons is equal to atomic number of the element.
What element has 46 protons and 55 neutrons?
The number of protons defines an element - the number of neutrons isn't needed to find the identity of the element. All ions and isotopes with 44 protons is ruthenium. However, with the information about the neutrons, we know the specific isotope: 101Ru.
What is the number of neutrons in atom I131?
Iodine is element number 53 and and so has 53 protons. There are thus 131-53 = 78 neutrons
What is an element is determined by the number of?
The identity of an element is determined by the number of protons in the nuclei of its atoms. This is the atomic number of an element.
How do you determine how many protons are in an element?
Experimentally, I'm not sure, but I know you can look at your periodic chart, the large number over the symbol of each element is teh number of protons in that element.
What number is the number protons an element has?
There are many different types of elements, all varying in the number of protons they contain. To determine the number of protons in a specific element, refer to the periodic table of elements. The atomic number (generally listed above the element's symbol, sometimes represented as 'Z') is equal to the number of protons in that atom.
What is the number of protons for an element is the same as the number of the subatomic number?
By definition, the number of protons in the atoms of an element is the atomic number of the element.
Atom of a particular element has a unique and characteristic number of these particles?
Each element has a unique number of protons. If another atom has the same number of protons as that element, it is the same element.
How many nucleons are in the atom of iodine-131?
The 131 number is the mass number: the sum of the number of protons and neutrons. Iodine has 53 protons and will have 53 electrons if its a neutral atom. To find the number of neutrons, just subtract the mass number with the number of protons 131 - 53 = 78 neutrons. See link below for periodic table.
