number of protons = Atomic Mass
it is the atomic number.
The atomic number is equal to the number of protons and the number of neutrons in that atom.
It is equal to the atomic number. Elements are arranged according to atomic number in periodic table
There is none, but a neutral atom is called a neutron. There is no neutral element.
In an atom of an element, the amount of protons in that atom equal the amount of electrons in the atom, but only if it is a neutral atom. That then eqals the atomic number of that element.
Reference the atomic number of the atom on the periodic table. The electron count is generally equal to the number of protons
The atom's atomic number is equal to the number of protons in its nucleus.For example, an element with 19 protons in its nucleus is Potassium (K), the 19th element on the periodic table.
The atomic number or the number of electrons is equal to the number of protons.
atomic number is how much protons(positive atom) and neutrons(neutral atom) are there in an element. therefore an atom does not have an atomic number
To determine the number of electrons for an element on the periodic table, you can look at the element's atomic number. The atomic number represents the number of protons in the nucleus of an atom, which is equal to the number of electrons in a neutral atom.
Smallest atom is hydrogen Largest atom is Francium
- Atomic number is equal to the number of protons - Atomic number is equal to the number of electrons (in a neutral atom) - Atomic number is the number of a chemical element in the periodic table of Mendeleev
