The atomic number of an element accounts for the number of protons in the nucleus of the atom of that element. For example:
* Hydrogen atomic number is one. The nucleus of its atom has one proton. * Oxygen atomic number is 8. The nucleus of its atom has 8 protons. * Iron atomic number is 26. The nucleus of its atom has 26 protons. * Lead atomic number is 82. The nucleus of its atom has 82 protons. * Uranium atomic number is 92. The nucleus of its atom has 92 protons.

What number represents the number of protons in an atom?
Protons are represented by the atomic number of an element. The number of protons is also the number of electrons. The number of protons is also represented in re Atomic Mass, which is the number of protons and the number of neutrons combined.
A sub atomic particle which determines the atomic number?
The atomic number of an element is equal to the number of protons in the nucleus of that element.
Which particles account for the difference between the atomic number and the mass number?
The answer is that it is neutrons that account for the difference between atomic weight and atomic number. The atomic number is the number of protons or the number of electrons in the atom, since they are normally equal. The atomic weightis the sum of the total number of protons, electrons AND neutrons in the atom. Knowing both the atomic number and the atomic weight of an atom lets you know the number of neutrons in the atom (the isotope). Example: Uranium, Atomic Number 92, Atomic Weight 235. The atomic number tell you that the uranium atom has 92 protons and 92 electrons. The atomic weight tells you that it has a combined total of 235 protons, electrons and neutrons. Since you know from the atomic number that there is a total of 184 protons and electrons in the atom (92 + 92) and from the atomic weight that the total number of protons, electons and neutrons is 235 (92 + 92 + X = 235), you now know that there are 151 neutrons in that uranium atom. The atomic number and atomic weight together tell you that the uranium atom 235 has 92 protons, 92 electons and 151 neutrons.
What determines an attoms atomic number?
The number of protons.
What is the particle that identifies a atom?
The number of protons in an atom's nucleus determines its chemical identity.
How many protons and electrons does vanadium have?
Vanadium has 23 protons. The atomic number is the same as the number of protons.
What is the total number of protons and neutron's in an atom called?
mass number = protons + nuetrons
Atomic number is equal to?
no of the protons or the no of electron is equal to the atomic no denoted by the symbol Z
The number is the number of protons in the nucleus?
atomic number is the number of protons
How can you find the number of protons?
The number of protons is the atomic number.
Define the term mass number?
Mass number is a value approximate to the number of protons (Atomic Number) plus the number of neutrons within an atom of the element considered. I say approximate as mass number takes into account the mass of the nucleus and not the actual number of protons and neutrons in the nucleus.
Which number is equal to the number of protons in the atoms?
The number of protons is identical to the number of electrons when an atom is in a neutral state.
