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
What is made up of a fraction and whole number?
A mixed number is made up of a whole number and a fraction.
Atomic mass and number for carbon?
atomic mass of carbon=12 atomic number of carbon=6
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.
Who made atomic numbers?
M.GMosly found the atomic number. Atomic number is equals to protons.
What particles make up the atomic number on a periodic table?
the number of protons make up the atomic number
What is the atomic mass of atoms made of?
The Atomic Mass is made up of protons and neutrons (which is basically the nucleus.)
What makes up an atomic?
"number of protons in an atomic nucleus"
The Periodic Table is set up in order of what?
in the increasing order of atomic number
The sum of the protons and the neutrons will tell the atomic what?
Atomic mass number of the atom. The best way to remember it is: the majority of the mass of an atom is made up of the protons and neutrons (the electrons are very light!), therefore the atomic mass number is the sum of the protons and neutrons.
Is elements atoms?
Elements are made of atoms. Each element is made up of the same kind of atoms, having the same atomic number.
What is atomic mass is made of what?
The Atomic Mass is made up of protons and neutrons (which is basically the nucleus.)
What does subatomic particles contribute to the value of atomic mass and atomic number?
protons is the same number as the atomic number always and protons plus the average number of neutrons makes up the atomic mass
What makes up the atoms mass number?
The mass number is the average total of the number of protons and neutrons in the atomic nuclei of all the isotopes of that element on earth. Thus, the average number of neutrons in that element can be found by subtracting the atomic number from the mass number.
How is an atomic weight different than an atomic number?
atomic weight goes up faster
