What is polyatomic number?
Polyatomic number are ions made up of more than one atomic element
What is another word for atomic number?
Atomic number is the equivalent of the number of protons in an atomic nucleus.
What is the square root of the atomic number of helium?
Weird concept, but: Atomic number of helium is 2, so its square root is √2. √2 is an irrational number so only an approximate decimal expansion can be made: √2 ≈ 1.4142
Atomic mass and number for carbon?
atomic mass of carbon=12 atomic number of carbon=6
What is made up of a fraction and whole number?
A mixed number is made up of a whole number and a fraction.
An element is?
An element is a substance made up of atoms with the same atomic number
What is polyatomic number?
Polyatomic number are ions made up of more than one atomic element
Who made atomic numbers?
M.GMosly found the atomic number. Atomic number is equals to protons.
Why does proton and electron are equal atomic number?
They have not atomic numbers. Atomic number is made by number of protons an atom has.
What is a substance in which one or more atoms have the same number of protons or atomic number?
Element
What particles make up the atomic number on a periodic table?
the number of protons make up the atomic number
What is the atomic number of Wheat?
There is no atomic number for wheat, because wheat is not an element, it is made up of many elements. I don't know exactly why you are asking this, but if someone told you there is an atomic number for wheat, then you are mistaken, and they are probably playing a trick on you, and embarrassing you.
Is this statement correct atoms are made up of nucleus and electrons composed of protons whose number is called the atomic number and neutrons whose numbers added together make the mass number?
It's close, but an atom is made of a nucleus and electrons. The nucleus is made of protons and neutrons. The number of protons equals the atomic number of the element, and the atomic mass is the number of protons plus neutrons.
If an atom is made up of 6 protons 7 neutrons and 6 electrons then what is it's atomic number?
All you need to determine the atomic number is the amount of protons, because it is these sub-atomic particles which enable us to identify an atom. All atoms of the same element have a unique number of protons. In this case, the atomic number is six.
What is the atomic number of Na3PO4?
Only elements have atomic number. Na3PO4 is not an element it is a compound called Sodium Phosphate. It is made of Sodium(Atomic number 11), Phosphorus(Atomic number 15) and Oxygen(Atomic number 8)
What is the atomic number of diamond?
Diamond does not technically have an atomic number as it is not an element. a diamond is a crystal made from many atoms of carbon which has an atomic number of 6.
How many nucleons does an oxygen with a mass number of 17 and an atomic number of 8 have?
There are no 'nucleons' in an Oxygen atom. You mean 'neutrons'. As all the mass of an atom is in its nucleus (made up of 'protons' and 'neutrons') and as the Atomic Number is the count of how many 'protons' there are, if you subtract the Atomic Number form the Atomic Mass, you get the number of 'nutrons'. 17-8=9.
