The atomic number of an atom is the number of protons in that atom. For example, the atomic number of hydrogen is 1 because one hydrogen atom have one proton.
An atom contains Protons, Neutrons and Electrons the atomic number is the protons and neutrons combined, the number of protons in the atom is equal to the total number of electrons in the atom which are aranged in the outer shells at 2,8,8,8,8 and so on to find the totoal number of protons in the neucleus of the atom you take the atomic mass and minus the atomic number from it. so He or Helium is 4.0026 atomic mass and 2 for atomic number and so has 2 protons and so in turn has 2 electrons.
Yes. If the number is unequal, it is an ion.Yes that is correct. The atomic number is equal to the number of electrons which equals the number of protons
The atomic number is the number of positive protons present in the nucleus of an atom.
The atomic number tells you how many protons and electrons are in a specific element.Atomic number tells us about protons. Number of protons that atom contains.
The whole number, the one at the top, above the element's symbol in the element box, is the atomic number. The atomic number is the number of protons per atom in that particular element. The bottom number, that is always a decimal, is the atomic mass.
The number of protons in an atom is equal to its atomic number.
In a neutral atom the number of protons is equal to the number of electrons. And by definition the atomic number of an atom is equal to the number of protons in it. So the atomic number of a neutral atom is equal to the number of protons or the number of electrons in the atom.
The number of protons is equal to atomic number; in a neutral atom the number of electrons is also equal to the numbers of protons.
Atomic number is always equal to the number of protons in an atom.
The atomic number is equal to the number of protons in the atom, it is also the element's identity. if the atom is a neutral atom, the atomic number is equal to the number of protons AND the number of electrons
The number of protons is equal to the atomic number of an atom
The atomic number is equal to the number of protons [note correct spelling!] in each nucleus of an atom.
The atomic number is equal to the protons and electrons of an element.
The atomic number reflects the charge number of the nucleus. It is always equal to the number of protons found in the nucleus.
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.
It is equal to the difference between atomic number and Atomic Mass number. A+
The number of protons is identical to the number of electrons when an atom is in a neutral state.
