I think it is because Protons Neutrons and Electrons are comprised of even smaller particles such as quarks leptons etc... and there might be different amounts of those particles in each proton neutron etc...
The atomic number of the element is the number of protons, therefore there has to be the same amount of electrons to protons.
The atomic number of an element is how many protons and electrons (you must have the same amount of protons as electrons) an element has in it's nucleus. The Atomic number= number of protons= number of electrons.
none because the number of protons and electrons have to be the same.
Element X with 72 protons will have 72 electrons in a neutral state. The number of protons in an element is equal to the number of electrons in that element's neutral atom.
the number of protons in an element is called the atomic number and there is no way to see how many electrons an element has.
the number of protons in an element is called the atomic number and there is no way to see how many electrons an element has.
The atomic number = Number of protons = Number of electrons
In an atom of any isotope of any element, there is a number of protons which is similar to the number of electrons.
The number of protons, electrons, and neutrons:P
The number of protons plus the number of electrons isn't a recognized figure in chemistry. The number of protons is the atomic number of an element. The number of electrons is the same as the number of protons except when the element is an ion. An ionic compound results in one or more electrons moving from one element to another element. Although this is a simplification, it can be described as the atom gaining or losing electrons. The number of protons plus the number of neutrons is the atomic weight of an element.
An element's atomic number is equal to the amount of protons in that element. Each atom has a different number of protons and electrons present in their make-up.
The number of protons determine the atomic number of an element. There are the same amount of protons as electrons in a regular element.
