Atoms of the same element differ in the number of neutrons in their nuclei. All atoms of a given element have the same number of protons, of course. The number of protons in a nucleus determines which element the atom is. But the number of neutrons can vary, and these different "versions" of a given element are called isotopes of that element. See the related question, which is linked below.
No, atomic number equals the number of protons.The number of neutrons is NOT specific to an element, and various atoms of the same element can have different numbers of neutrons - these are called isotopes.
the only element with a mass number of 22 is sodium (Na) which has an atomic number of 11. This is because the atomic number only represents the number of protons in the nucleus, while the mass number represents the number of protons and neutrons in the nucleus.
All elements have three subatomic particles: Protons: positive forces, centered in the nucleus of the atom with neutrons Neutrons: neutral forces, centered in the nucleus of the atom with protons Electrons: negative forces, centered in different energy levels outside the nucleus of the atom Between all these particles, there is only empty space; nothing.
In a Hydrogen nucleus there is a proton. Hydrogen is the only element to not have a neutron in it's nucleus.
An atom with one proton and no neutrons in its nucleus is a hydrogen-1 atom, also known as protium. It is the most common isotope of hydrogen and is the simplest and lightest chemical element.
Hydrogen is the only element without any neutrons in its nucleus. It consists of only one proton and one electron.
There is no ELEMENT which contains no neutrons HOWEVER there is an isotope of hydrogen called protium which is a single proton surrounded by a single electron.
Isotopes of one particular element differ only in their number of neutrons in nucleus.
The element hydrogen is the only element that lacks neutrons in its nucleus, consisting only of a single proton and an electron.
Only hydrogen has un-isotopic atoms without a neutron. Hydrogen can sometimes though have one or so neutrons in its isotopes. The other elements must have neutrons to keep the protons from repelling each other in the atom's nucleus.
No, the atomic weight of an element is not equal to the number of protons minus the number of neutrons. Atomic weight is the average weight of an element's isotopes taking into account their abundance, which includes the sum of the protons and neutrons in the nucleus.
It all depends on which element you are speaking about. Some only have one and some have many.
The most abundent isotope of Hydrogen has only a proton for a nucleus with a single electron orbiting it. However some isotopes of Hydrogen do have neutrons in the nucleus.
Atoms of the same element that have different numbers of neutrons are called isotopes. An isotope is known by its mass number, which is the sum of the protons and neutrons in its nucleus.
Number of protons in in an element denote the type of element. So you identify element on the number of protons in it. Protons being positively charged can not sit together in a nucleus. They will repel each other. So you do not have an element in which only 2 or more protons and no neutrons are there.It means neutrons act as binding material in an element. So usually equal or more neutrons are there in an element. If same number of neutrons are there in nucleus but different number of protons, then it is no more a same but different element. An element in which different number of neutrons are there are called as Isotope. All element have got one or more Isotopes. So there 'physical' properties would differ but not 'chemical' property.
There is only one nucleus in the atom hydrogen because it is a single element. It isn't a compound therefor it only has one nucleus to its makeup. There is only one nucleus in all atoms. The nucleus is the center of an atom. It holds the protons and neutrons of the atom while the electrons orbit the nucleus in the electron cloud.
