you take the Atomic Mass of an atom say, 16 for oxygen, and subtract the atomic number, 8 for oxygen. 16-8= 8. so there are eight neutrons in the typical oxygen atom.
What else can I help you with?
In periodic table of elements it is the sum of the number of protons and neutrons of an atom.?
The sum of protons and neutrons is the atomic mass.
What subatomic particle makes the periodic table in the order of elements that it is in?
The order of the periodic table is made according to the atomic weights of the elements. The number of protons and neutrons in the nucleus make the atomic weight. Protons make the elements in order of the periodic table.
Why is the number of elements on the periodic table unfixed?
If your talking about the atomic mass number it is because the amount of neutrons can very. If you are talking about the actual amount of total elements on the periodic table it is because we keep discovering new things.
What is the 150th element in the periodic table of elements?
After taking out my periodic table of elements, the closest i could find would be Californium, with 153 neutrons, Berkelium, with 152 neutrons, and finally Curium with 151 neutrons. This can be found by taking the atomic number of an element (which is the number of protons it has) and subtracting it from the elements atomic mass (which is the number of protons and neutrons added together). No element has a perfect 150 neutron number, but in its most stable isotope form Curium appears to be the closest.
What is the name of the table of elements?
It is named The PERIODIC TABLE. The periods being the horizontal rows The groups being the vertical columns.
In periodic table of elements it is the sum of the number of protons and neutrons of an atom.?
The sum of protons and neutrons is the atomic mass.
Where is the location of the neutrons in a periodic table?
Neutrons are not given directly on the periodic table. However the number of neutrons can be indirectly calculated. Mass number = Number of protons + number of neutrons
Where are the nuetrons found on the periodic table?
Neutrons are sub-atomic particles. The Periodic Table is an arrangement of the elements (atoms) made from these subatomic particles. Thus Neutrons by themselves have no place in the Periodic Table. However as all elements/atoms (except Hydrogen) contain some Neutrons, it is possible to find out how many using the information presented on the Periodic Table. The number of Neutrons present in an element/atom can be determined by subtracting the atomic number of an element/atom from its atomic mass.
Why is uranium on the periodic Table of elements?
Because it is elemental. That is: it is not an alloy. It has a unique number of protons and neutrons.
How do you count the number of neutrons and protons in an atom?
The number of protons in an atom is its atomic number, which you can find on the periodic table. To calculate the number of neutrons, subtract the atomic number from the atomic mass listed on the periodic table.
What is the name of the table that shows an element symbol and its name the number of protons and neutrons of the element?
The Periodic Table of the Elements includes most of this information (but not the number of neutrons). The Chart of the Nuclides (or Table of the Isotopes) includes all of the information.
How are the elements arranged?
Elements are arranged on the periodic table based on their atomic number, which is the number of protons in their nucleus. This arrangement groups elements with similar properties in columns called groups or families, while elements in the same period have the same number of electron shells.
What subatomic particle makes the periodic table in the order of elements that it is in?
The order of the periodic table is made according to the atomic weights of the elements. The number of protons and neutrons in the nucleus make the atomic weight. Protons make the elements in order of the periodic table.
Why is the number of elements on the periodic table unfixed?
If your talking about the atomic mass number it is because the amount of neutrons can very. If you are talking about the actual amount of total elements on the periodic table it is because we keep discovering new things.
How do you find the mass number on the periodic table for the elements are calculated?
The mass number is the number of protons plus the number of neutrons in the atomic nucleus.
Do all elements of the periodic table have the same type of atoms?
No. Atoms differ in number of protons, neutrons and electrons.
Why did they number elements on periodic table?
No one give number to elements in periodic table. they have been calculated
