the atomic number is 2
The atomic number of hydrogen is 1.
Calcium
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
Atomic weight of an element is the number of protons plus neutrons in the nucleus, atomic number is the number of protons only.
I don't want to do your homework for you. Here's how you figure it out: Protons = atomic number Neutrons = atomic mass - atomic number Electrons = atomic number + ionization
The atomic number of fluorine is 9.The atomic number of sodium is 11.
The atomic number of hydrogen is 1.
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.
No, Atomic number is the number of protons in an atom. Atomic mass is the number of protons plus the number of neutrons.
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
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
Calcium=Ca=Atomic number 20 9+11=20
Hydrogen is a non metal element. Atomic number of it is 1.
