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.
What is the atomic mass of gallium with 39 neutrons?
The atomic mass of an element is the sum of protons and neutrons in its nucleus. Gallium has an atomic number of 31, which means it has 31 protons. If it has 39 neutrons, then its atomic mass would be 31 (protons) + 39 (neutrons) = 70.
The number of protons contained in each element gives that element what number?
The number of protons in the nucleus of an element gives that element its 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?
An atom with 37 protons is the element rubidium (Rb).
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 element has 25 protons 25 electrons and a mass number of 56?
The element with 25 protons and 25 electrons is manganese (Mn). The mass number of 56 suggests that this particular manganese atom has 31 neutrons (mass number - atomic number).
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.
The number of protons in an atom of an element?
The number of protons in an atom of an element is its atomic number. It determines the element's identity and is unique for each element. The number of protons also defines the element's chemical properties.
How do you determine how many protons are in an element?
The number of protons in an element is determined by its atomic number, which is the whole number found on the periodic table for each element. Each element has a unique number of protons that gives it its specific identity.
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 is equal to the number of protons in an element?
The number of protons in an element is equal to its atomic number.
