The identity of every element is given by the number of protons in the nucleus. To keep electrical neutrality, they also have the same number of electrons.
See the Related Questions for more information about protons, neutrons, and electrons in atoms.
All atoms of an element have the same "atomic" number, which is the number of protons. They also usually have the same atomic weight, which is the number of protons plus the number of nuetrons (approximately). However, atoms of the same element can have a different number of neutrons. If the number of neutrons is not the standard number, it is an isotope. If the number of electrons is not the standard number, it is an ion. If the number of protons is not the standard number, it is a different element.
Protons and thus electrons too in order to maintain electrical neutrality.
Yes, conversely, all the atoms with same number of protons are of the same element or species.
Atoms of an element have the same number of protons in each nucleus.

Atoms of elements in the same group have the same number of valence electrons.

No. All atoms of the same element have the same number of protons and, when neutral, the same number of electrons. They can, however, differ in the number of neutrons.
They all have the same number of neutrons. All atoms of a given element have a specific number of protons. That is what gives an element its elemental identity. But we know that different atoms of a given element can have different numbers of neutrons. These different atoms of the same element are the isotopes of that element. All the atoms of a given isotope of a given element will have the same number of protons and will have the same number of neutrons. all isotopes of an atom have same number of proton but they have different number of neutron so they have same chemical properties and different physical properties. all isotopes of an atom have same number of proton but they have different number of neutron so they have same chemical properties and different physical properties.
No. All atoms of a given element are alike in the number of protons, which is the atomic number of an element. However, the number of neutrons in the nucleus can vary. Atoms of elements with the same number of protons but different numbers of neutrons are called isotopes. All atoms of a given element in their ground state have the same number of electrons as they do protons, but if they form ions, the number of electrons will increase or decrease, depending on the element, but the number of protons remains the same.
All atoms of a given element have the same number of protons in a nucleus. It is the number of protons in an atom's nucleus that determines the elemental identity of any atom. Period.
Element refers to atoms that have the same number of Protons.
Atoms of a given element always have the same number of protons in their nucleus. Neutrons can vary (in different isotopes) and electrons can vary (in different ions) but protons are always the same for a given element. If the number of protons is changed, then you no longer have the same element.
The same number of protons, which is also the atomic number of the element.
No - different isotopes of an element have different numbers of neutrons. All atoms of an element will have the same number of protons.

All atoms with the same number of protons are atoms of the same element. The number of protons is the atomic number of the element.
In respect to different elements, no they don't, in respect to like atoms of one particular element, yes they do. The electrons are the particles that vary from like atoms of the same element. When the electrons and protons are uneven within an atom, you have a radioactive element.
An element is defined a "type of atom"; to be more precise, all the atoms in an element have the same number of protons (but not necessarily the same number of neutrons).
Isotopes are atoms of a given element that have the same number of protons but a different mass number and therefore a different number of neutrons.
An isotope has same number of protons but a different number of neutrons as the original element in the atomic nucleus; it has the same atomic number as the element which isn't an isotope, but will have a different mass number. -atomic number
No. All atoms of a given element are alike in the number of protons, which is the atomic number of an element. However, the number of neutrons in the nucleus can vary. Atoms of elements with the same number of protons but different numbers of neutrons are called isotopes. All atoms of a given element in their ground state have the same number of electrons as they do protons, but if they form ions, the number of electrons will increase or decrease, depending on the element, but the number of protons remains the same.
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.
