The atomic number
The number of protons and electrons of the atom in a neutral state.
The atomic number is the number of protons in an element. Ex: Molybdenum's A.N. is 42. so it has 42 protons.
The atomic number equals the number of protons in an atom, as well as the number of electrons in a stable, electrically neutral atom, it represents the identity of an element ,the simplest form of matter.
The atomic number is the number of protons in the nucleus of one atom of the element.
The atomic number of an element is the number of protons in each atom of the element, whether neutral or not. If the atom is neutral, the number of electrons in the atom is the same as the number of protons.
The number of protons and electrons of the atom in a neutral state.
The atomic number represents the number of protons. The atomic mass represents the number of protons + neutrons.
The atomic number represents the number of protons in the element. This number is unique to that element, if you change the atomic number (number of protons) then you change the element.
An element's ID number is the atomic number, which represents the number of protons in the nucleus.
The element symbol represents one mole of element , atomic number represents number of protons, atomic mass represents sum of protons and neutrons.
It represents the number of Protons (p+) that element has in the nucleus of one atom.
The atomic number of an element also represents the number of protons in that element.
... of protons in the nucleus of each atom of the element.
The atomic number of an element represents the number of protons in each atom of the element.
It represents the number of protons and the number of electrons in an atom of the element.
It represents the number of protons and the number of electrons in an atom of the element.
Atomic numbers are the number of protons and electrons in a atom.
