it is simple. all you need to do is look in the Periodic Table the numbers above and under the letter.
Atomic number is determined from the number of protons in the nucleus. Atomic Mass is determined from the number of protons AND neutrons in the nucleus. Since elements have multiple isotopes with differing numbers of neutrons, the atomic mass reported on periodic charts is usually the average atomic mass. As the first person who answered this question pointed out, you can usually find the atomic number by looking for a number above the atomic symbol for the element in the the table (H for hydrogen, C for carbon, Fe for Iron, Au for gold, etc.). Sometimes the number will be below the symbol but in bold font. When the periodic table gives an atomic mass, it is usually given under the atomic symbol and is almost always some kind of decimal number that is always greater than the atomic number, for example: Carbon has an atomic number of 6and an atomic mass of 12.0107 amu.
We can find atomic mass and mass number in chemical elements. Atomic mass is about weight of the atom. Mass number is about total of neutrons and protons.
We can find Atomic Mass and mass number in chemical elements. Atomic mass is about weight of the atom. Mass number is about total of neutrons and protons.
The atomic mass number of iodine is 17.8923
Atomic number 6, atomic mass 12.
atomic mass of carbon=12 atomic number of carbon=6
We can find Atomic Mass and mass number in chemical elements. Atomic mass is about weight of the atom. Mass number is about total of neutrons and protons.
We can find atomic mass and mass number in chemical elements. Atomic mass is about weight of the atom. Mass number is about total of neutrons and protons.
83.98 amu is the Atomic Mass, 36 is the atomic number.
The atomic number is the number of a chemical element in the periodic table of Mendeleev; the atomic number is equal to the number of protons and electrons. The atomic mass is the mass of an atom expressed in relative atomic mass units.
atomic number = number of protons = number of electrons atomic mass = mass of protons + mass of neutrons
The atomic number is 88 and the atomic mass is 226
Number of neutrons = Mass number - atomic number
No, the atomic mass number is the number of protons plus the number of neutrons. The atomic mass of an atom is the total mass in a motionless atom.
Atomic mass is the mass of 1 mole of the element. Atomic number is the number of protons the element has
We can find atomic mass and mass number in chemical elements. Atomic mass is about weight of the atom. Mass number is about total of neutrons and protons.
We can find atomic mass and mass number in chemical elements. Atomic mass is about weight of the atom. Mass number is about total of neutrons and protons.
The atomic mass is equal to the number of protons plus neutrons. So if you know the atomic number then you can find out the number of neutrons Atomic # is the amount of Protons or Electrons Atomic Mass- Number of protons plus neutrons Atomic Mass-Atomic Number = Amount of neutrons
