Atomic number = number of protons = number of electrons (in the neutral state)
The atomic number of an element equals the number of protons in the element.
The atomic number is equal to the number of protons and neutrons in a neutral atom.
The atomic number is 5becuse it is in the nuclise
Positive charged particles in atomic nucleus - protons. Number of protons = atomic number (The number of a given element in the Mendeleev table)
The atomic number of an element is determined by the number of protons.
There is no element whose symbol is An.
"Atomic number" is a characteristic of a chemical element and equals the number of protons in each nucleus of an atom of the element.
The number of protons
False; the atomic number is the total number if protons in the nucleus only.
Either the number of protons or the number of electrons in a neutral atom is equivalent to its atomic number.
Calcium(C)
The number of protons determines the element, and is the same as its atomic number.
