It is usually the biggest number in each elements box otherwise it is the number that is next in line from the one in front or behind the next element
Its atomic number is 2.
We don't need to. The atomic number is based on the number of protons. Since all elements as they appear in the periodic table have the same number of protons and electrons, if we know one, we know the other.
by the atomic number.
The atomic number is equal to the number of protons in the atomic nucleus. It is an individual characteristic.
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
Oxygen is a gas. atomic number of it is 8.
The number of protons is equal to the element's atomic number on the periodic table. Hydrogen, atomic number one, has one proton. Carbon, atomic number six, has six protons. Alternatively, if you know the number of electrons on a neutral atom, the number of protons will be the same.
You subtract the atomic number from the mass number.
This one is based one uranium. It is a radioactive one. Uraniums atomic number of that is 92.
We don't need to. The atomic number is based on the number of protons. Since all elements as they appear in the periodic table have the same number of protons and electrons, if we know one, we know the other.
The elements are arranged with increasing atomic number
by the atomic number.
ex.8 16.00OOxygenIt's name is OxygenThe table shows the fact that it is a non-metal8 is the Atomic Number(The number of protons in one atom of the element)16 is the Atomic Mass(Total number of protons and neutrons in one atom of the element)Another way to tell the Atomic Number and the Atomic Mass is that the Atomic Number is always smaller then the number of Atomic MassProton:8Electron:8Neutron:8We know the number of proton and electron from the atomic number.The number of electon is always the same as the number of proton.So the atomic number is 8 and the number of proton and electron is 8To know the number of neutron, we have to do some math.Atomic Mass equal the number of protons puls neutrons.So we have to take the number of Atomic Number MINUS Atomic Mass.16 - 8 = 8So the number of neutron is 8.From the periodic table, we can also know the name of the element and what is it called in the scientic way.It also shows the configuration of electrons based on its location in the table.
Hydrogen has atomic number 1.
You look up antimony. You discover its symbol is SB. You look on your periodic table. You come to the symbol SB. You see that it is number 51. You know that is also the number of protons in the atom. You know that 122 is the atomic weight. You know that the Atomic Weight mainly comes from the weight of the neutrons and protons. You know that when you have the atomic weight you can subtract the atomic number from the atomic weight and get the number of neutrons.
The atomic number is equal to the number of protons in the atomic nucleus. It is an individual characteristic.
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
