What else can I help you with?
What is an atomic atom?
It's what everything in this world is made up of. It makes up matter.
What elements do helium make up?
The only element helium makes up is helium. Atomic number: 2 Atomic weight 4.00260 u (avg)
What sub atomic particles makes up mass of an atom?
Protons and neutrons
What makes up the atomic weight of an atom?
The total weight of the protons and the neutrons.
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 is the basic material that makes up all matter and is different from any other in its atomic structure?
The basic material that makes up all matter and is different from any other in its atomic structure is the element. Each element is defined by the number of protons in its nucleus, which determines its unique atomic number.
Which sub atomic particle makes up most of the mass of atom?
These particles are proton and neutron.
Smallest unit of organization?
sub-atomic particle: which makes up an atom: which makes up molecules: which makes up DNA: which make up organelles (cell parts): which makes up cells: which makes up tissues: which makes up organs: which makes up organ systems: which makes up organisms.
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.
What makes lead?
Lead is an element, Pb, so lead makes up lead! It has 82 protons, 82 electrons, approx. 125 netrons and an Atomic Mass of 207.2
Who makes atomic bombs?
The governments of various states.
What is the most common isotope for boron?
