they are the same element because an element has an atomic number through its number of protons so if there was an element with 2 protons it would be number 2 in the Periodic Table which is helium, if another element has 2 protons it should be helium still, if it wasn't modified in anyway
Two atoms that have the same number of protons are called isotopes.
No. Atoms have the same number of protons and electrons. When atoms gain or lose electrons they are called ions.
Proton Number
The number of protons.
atoms had gained or lost one or more electron are called ions. so no. the number of neutron and proton don't change. unless it was isotope you are talking about. they have the same atomic number but different atomic mass, which means different number of neutron.
Yes, surely the same + and - charge
The number of protons in the nucleus will ALWAYS be the same for a specific element.(ex: Hydrogen always has EXACTLY 1 proton)But, the number of electons and neutrons can vary in a particular element.
An element is composed of atoms all with the same proton number(they are the same type). The only way the atoms in an element can vary is in the number of neutrons they have.
Wrong! For example we take on hydrogen atom which has 1 proton in his nucleus and one electron 'gravitating'(gravitating is not an appropriate word because of the quantum origin of all elementary particles, as they can be expressed both either parcitle if they are observed, or a wave) In nature there is a "heavy" atom of hydrogen which is called deuterium. It has 1 proton and 1 neutron in its nucleus. There are 3 types of hydrogen atoms known. The pattern is the same for almost all elements.
isotopes Atoms of the same element are called Isotopes. they have the same number of atoms (i.e. same atomic number) but different number of neutrons
