Atomic number of an atom is equal to the number of?
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.
In a neutral atom is the number of protons equal to the number of 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
What does the atomic number tell you about the atomic structure of any element?
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.
What do whole numbers on the periodic table represent?
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.
What information does the atomic number of an element give you?
The atomic number is how many protons there are, and since the number of protons is equal to the number of electrons, it is also the number of electrons. You can take the number of protons away from the atomic weight (overall weight) which will give you the number of neutrons. (Electrons don't weigh anything in the atomic weight so you don't need to subtract this as well). Hope this helps :D
What atomic particle is equal to its atomic number?

What is the atomic number also equal to?

What does the atomic number repersents?
The atomic number is equal to number of protons in the atomic nucleus.
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
Are the number of neutrons equal to the atomic number minus the atomic mass?
false
Is the atomic number the number of atoms it has?

The atomic number of an element is equal to the number of contained in one atom of that particle?
The atomic number of an element is equal to the number of protons contained in the atomic nucleus.
What does the atomic number always equal inside an atom?
Atomic number is always equal to the number of protons in an atom.
Is the atomic number of an atom equal to its number of protons and the atomic mass is equal to its number of neutron Protons?
yes
What best describes the number of neutrons in an atom?
It is equal to the difference between atomic number and Atomic Mass number. A+
What gives an element it's atomic number?
Atomic number is the number of protons (i.e. equal to the number of electrons) of an atom.
