isotopes
Isotopes are alternate forms of elements with differing neutron numbers. Isotopes have the same number of protons (and thus the same atomic number), but different numbers of neutrons, leading to variations in atomic mass. Some isotopes are stable, while others are radioactive and undergo decay.
It still has 7 protons because isotopes of elements have variable NEUTRON numbers, not nucleon (atomic mass) or proton numbers.
They are called as isotopes of the given element.
Regular elements contain regular neutron number and the same number of protons and neutrons. Isotopes have different neutron numbers than the original element, but the same number of protons and electrons.
isotopes
no, they are arranged by their protons.
Atomic Mass of element - the number the protons.
All atoms of the same element have the same number of protons. Atoms of different elements have differing numbers of protons.
Different elements have different numbers of protons. The number of protons identifies the element.
NO. Isotopes are forms of an element that have the same numbers of protons and electrons, but differing numbers of neutrons. For example Helium-3 has two protons, two electrons, and one neutron and Helium-4 has two protons, two electrons, and two neutrons.A form of an element that has a different number of electrons than the number of protons is an "ion".
The answer you are looking for is "isotopes" HOWEVER, please note you CAN NOT HAVE 2 elements with the same number of PROTONS. This is because the number of protons DEFINES an element. Isotopes are the SAME element but with differing numbers of neutrons.
No, because some elements have Isotopes, with the same Proton number but different Neutron numbers. Sometimes therefore, the neutron number can overlap with that of isotopes of other elements. For example, two of Helium's isotopes share neutron numbers with two of Hydrogen's isotopes. Deuterium has 1 neutron, and so does 3He, Tritium has 2 neutrons, and so does 4He. It is the number of protons which determines which element it is.
