The atomic number is equal to the number of protons in the nucleus and in a neutral atom will also equal the number of electrons.
The atomic number is equal to the number of protons in the nucleus.
The number of protons in the nucleus of an atom
The atomic number of an atom is the atoms number of protons. The number of protons is same as the number of electrons.
protons in the atom, only
The atomic number of an element equals the number of protons in the element.
Atomic number describes about number of protons.It is equals to number of protons.

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 number
The atomic number of an element equals the number of protons in the element.
At No(F) + At No(Na) = 20.At No of Calcium = 20.
M.GMosly found the atomic number. Atomic number is equals to protons.
There is no element whose symbol is An.
Atomic number = number of protons = number of electrons (in the neutral state)
Yes.
Calcium=Ca=Atomic number 20 9+11=20
A hydrogen atom has one proton, one electron and '''zero''' neutrons. Rephrased, the question is: Hydrogen's number of neutrons equals mass number - atomic number.
Calcium(C)
