What information could you use to determine the atomic number of an unknown element that has a mass number of 22?
the only element with a mass number of 22 is sodium (Na) which has an atomic number of 11. This is because the atomic number only represents the number of protons in the nucleus, while the mass number represents the number of protons and neutrons in the nucleus.
Which notation represents an atom of sodium with an atomic number of 11 and mass number of 24?
An atom of sodium with an atomic number of 11 and mass number of 24 is 2411Na.
What does the mass number represent?
The mass number represents the weight of the protons and neutrons in Atomic Mass units (AMUs). One AMU is equal to one proton or neutron.The average mass of all isotopes of the element - apex.
What represents the number of protons and neutrons in an atom of uranium?
The number of protons is equal to the number of electrons and the atomic number. The number of neutrons is different for each isotope (number of neutrons = atomic mass of the isotope [or mass number] - number of protons).
What is the number above the elements symbol?
the number above the symbol is the atomic....... of that element.
What number represents the protons and nuetrons?
