If an atom of an element has a mass number of 31 and 16 neutrons in its nucleus what is the atomic number of the element?
12. the atomic number of an element is the number of protons in it's nucleus. The mass number is the number of protons+neutrons. Therefore the element has (32-20)12 protons.
Does phosphorus-31 have 16 protons?
No, Phosphorus 31 does not have 16 protons. All Phosphorus atoms have the same number of protons, since the number of protons is what determines which element it is. For phosphorus, the atomic number is 15, meaning it has 15 protons. Phosphorus 31 also has 16 neutrons and 15 electrons.
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.
The number of protons in its nucleus mean?
The number of protons in the nucleus identifies the element. It is like a fingerprint for that element. No other element will have that same number of protons. As soon as the number of protons in the nucleus changes, so does the identity of the element change.
What is The number of protons in an atom of an element is the element's?
The number of protons in an atom of an element is equal to the number of electrons in that atom which is equal to that element's atomic number.
Which elements has 31 protons?
It is the gallium element. Atomic number is 31.
An atom contains 37 protons what element is it?
the atomic number of any element is the number of protons in its nucleus, so in this case, 31, Gallium

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 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.
What element has 25 protons 25 electrons and a mass number of 56?
The isotope 56Mn has 25 protons, 25 electrons, 31 neutrons and a mass number of 56.
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.
The number of protons in its nucleus mean?
The number of protons in the nucleus identifies the element. It is like a fingerprint for that element. No other element will have that same number of protons. As soon as the number of protons in the nucleus changes, so does the identity of the element change.
