why atoms have different isotopes?

The atoms of a chemical element can exist in different types. These are called isotopes. They have the same number of protons (and electrons), but different numbers of neutrons. ... Because different isotopes have different numbers of neutrons, they do not all weigh the same or have the same mass.

Elements can be identified by their atomic number and mass number. Isotopes are atoms of the same element that have different masses. Atoms have a mass that is based largely on the number of protons and neutrons in their nucleus. ... The chemical elements are arranged in a chart called the periodic table.

Atoms of the same element, containing the same number of protons, but different numbers of neutrons, are known as isotopes.

Isotopes are atoms of the same element that have different numbers of neutrons but the same number of protons and electrons.

There's more to the atom than the electrons. ... The nucleus of an atom contains neutrons and protons bonded tightly together. The same chemical element can have a different number of neutrons and still be the same element. We refer to the atoms of the same element with different numbers of neutrons as "isotopes".

Atoms of the same element, containing the same number of protons, but different numbers of neutrons, are known as isotopes. Isotopes of any given element all contain the same number of protons, so they have the same atomic number (for example, the atomic number of helium is always 2).

Atoms of the same element can have different numbers of neutrons, however. Atoms of the same element (i.e., atoms with the same number of protons) with different numbers of neutrons are called isotopes. Most naturally occurring elements exist as isotopes.

Atoms of the same element can have different masses. Isotopes of the same element can have different numbers of protons.

The number of protons determines an element's atomic number and is used to distinguish one element from another. The number of neutrons is variable, resulting in isotopes, which are different forms of the same atom that vary only in the number of neutrons they possess.

The identity of an atom depends only on the number of protons, not on the number of neutrons. Many elements have atoms with the same number of protons but different numbers of neutrons. Atoms of an element that have different masses are isotopes (EYE-suh-TOHPS).

So they can all be atoms. An ion simply refers to an atom or molecule that has gained an electric charge by either gaining or losing at least one electron. ... Isotopes are atoms of the same element that differ in the number of neutrons. That is, they have the same number of protons, but different number of neutrons.

Answer Key The number of protons an atom has is called its atomic number, which decides what kind of atom it is. Changes in the number of neutrons make an isotope, and changes to the number of electrons make an ion. (A) They are made up of subatomic particles called protons, electrons and neutrons.

All atoms of the same element have the same number of protons, but some may have different numbers of neutrons. ... Different isotopes of an element generally have the same physical and chemical properties. That's because they have the same numbers of protons and electrons.

An isotope is one of two or more forms of the same chemical element. Different isotopes of an element have the same number of protons in the nucleus, giving them the same atomic number, but a different number of neutrons giving each elemental isotope a different atomic weight.

Isotope. Isotopes are atoms of the same element that have different numbers of neutrons, resulting in a different atomic mass. ... Each proton has a charge of +1, each electron a charge of -1, and each neutron has no charge (neutral charge--neutron).

Atoms of the same element (i.e., atoms with the same number of protons) with different numbers of neutrons are called isotopes. Most naturally occurring elements exist as isotopes. For example, most hydrogen atoms have a single proton in their nucleus.

Answer and Explanation: The atoms of different elements differ in the number of protons contained in the nucleus of their atoms. They can have the same number of neutrons and...
