the atomic number is 2
The atomic number of F (fluorine) is 9 and the atomic number of Na (sodium) is 11. Adding them together gives 20, which is the atomic number of calcium (Ca).
Hydrogen has an atomic number of 1, which means it has 1 proton in its nucleus. This is the defining characteristic of hydrogen as an element.
equal to number of protons
The sum of the number of protons and neutrons in an atom is known as the atomic mass. It is equivalent to the mass number of the atom, which represents the total number of protons and neutrons in the nucleus.
The first four: 1. Be 2. C 3. O 4. Ne How I found this: Since Helium (He) has an atomic number of 2, add two to the atomic number of Be. Since the atomic number of Be is 4, and the atomic number of Helium is 2, you would add four plus two, which equals six. Carbon has an atomic number of six, so therefore it would be your next answer. The formula is the atomic number of Helium plus the atomic number of element you are provided with equals the atomic number of your answer. In simpler terms: atomic number of He+atomic number= atomic number of answer
The atomic number of fluorine is 9.The atomic number of sodium is 11.
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
There is no element whose symbol is An.
We get the number of neutrons. Atomic number is the number of protons, and atomic mass is protons plus neutrons.
a number having no physical meaning.
The Atomic Number is the number of protons. The Atomic Mass Number is the number of protons plus the number of neutrons of a particular isotope.neutrons and protons
protons plus neutrons = atomic number
The atomic mass consists of the number of protons plus the number of average neutrons.
The atomic number of F (fluorine) is 9 and the atomic number of Na (sodium) is 11. Adding them together gives 20, which is the atomic number of calcium (Ca).
You think probable to sodium fluoride , NaF.
protons is the same number as the atomic number always and protons plus the average number of neutrons makes up the atomic mass
atomic number is the number of protons in an atom mass number is the number of protons plus the number of neutrons in an atom
