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.

How do you determine the isotope?

Isotopes are determined by the number of neutrons in an atom's nucleus. Each isotope of an element has the same number of protons in its nucleus but a different number of neutrons. Isotopes of an element have the same chemical properties but different atomic masses.


What is mass number of an isotope?

The mass number of an element is equal to the number of protons in the nucleus, and this always determines the element in the Periodic Table. Different isotopes of the same element have differing numbers of neutrons in the nucleus, but always the same number of protons.


What is the nucleus of an isotope with a certain atomic mass and number?

The nucleus of an isotope with a specific atomic mass and number contains protons and neutrons. The number of protons determines the element, while the sum of protons and neutrons gives the atomic mass. The neutrons in the nucleus help stabilize it by balancing the repulsion between positively charged protons.


Does an atom retain the chemical identity of an element?

An isotope is an atom that contains a different number of neutrons. In order for an element to change there has to be a different number of protons.


Describe the structure of a general atom using the three basic subatomic particles?

the smallest component of an element having the chemical properties of the element, consisting of a nucleus containing combinations of neutrons and protons and one or more electrons bound to the nucleus by electrical attraction; the number of protons determines the identity of the element.

Where do you find the neutrons on the element?

Neutrons are found in the atomic nucleus of an element, along with protons. They have no electrical charge and help stabilize the nucleus. The number of neutrons in an element can vary, leading to different isotopes.

Atom that has a nucleus with no neutrons?

An atom with a nucleus that has no neutrons is hydrogen-1, which consists of one proton and no neutrons. It is the simplest and lightest element on the periodic table.


How many particles are located inside the nucleus of an atom?

The nucleus of an atom contains protons and neutrons, which are collectively referred to as nucleons. The number of particles inside the nucleus varies depending on the element, as it is determined by the number of protons and neutrons present.


How does the mass of a nucleus differ from the mass of an electron?

There is no simple answer.The mass of a nucleus depends on the number of neutrons and protons in the nucleus. The number of protons in the nucleus depends on the element. Moreover, the number of neutrons can vary between isotopes of the same element.


What element has 148 neutrons in the nucleus?

An element with 148 neutrons in its nucleus is usually Gadolinium (Gd) with an atomic number of 64, as its atomic mass is approximately 157. There may be isotopes of other elements with 148 neutrons as well.


What is the major difference among isotopes of an element?

Number of neutrons in the nucleus.


Isotopes are forms of the same element that differ in what?

Yes, isotopes of an element are the same element but with different numbers of neutrons in the nucleus and thus different atomic masses.


What does a nucleus not contain?

An element's nucleus basically contains protons and neutrons. Electrons rotate around the nucleus of an atom.
