Because the number of neutrons is different for each isotope.

Atom of an element with a different number of protons?

This is not possible. The number of protons identifies an element, and all of the atoms of the same element have the same number of protons. The atoms of an element can, however, have different numbers of neutrons, and they are called isotopes.


What is the only way to change one element into a different element?

Through nuclear reactions, such as nuclear fission or fusion, it is possible to change one element into a different element. This process involves altering the number of protons in the nucleus of an atom, resulting in the creation of a new element with different atomic number and properties.


Atom of a particular element has a unique and characteristic number of these particles?

Each element has a unique number of protons. If another atom has the same number of protons as that element, it is the same element.


One of at least two possible forms of the same element?

A single element can have two different variations. An isotope is a variant caused by a different number of neutrons. An ion is a variation caused by a different number of electrons than the parent atom.


Can atoms of two different elements have the same atomic number and could they have the same mass number?

The atomic number, or Proton number, defines which element it is. So by definition, two different elements must have a different atomic number, or else they'd be the same element. Atomic mass is the number of protons + neutrons in the element's nucleus. Since the number of neutrons in the nucleus can vary, even within a single element (as isotopes) it is possible to have one isotope of one element sharing an atomic mass with an isotope of another element.


How many protons does darmstadtium have?

Number of neutrons = Atomic mass of an isotope - Atomic number of an element The atomic number of darmstadtium is 110; darmstadtium isotopes has massess between 267 and 281.


How is it possible for two atoms of the same element to have different masses?

Two atoms of the same element can have different masses if they contain different numbers of neutrons. These are known as isotopes of the element. Isotopes have the same number of protons and electrons, but differing numbers of neutrons, which can slightly alter their atomic mass.


What do different isotopes of a particular element contain the different number of?

Isotopes of a chemical element have a similar number of protons but a different number of neutrons.


What number identify an element?

The atomic number of an element is equal to the number of protons in the nucleus of that element; it will identify the element. The number of neutrons of a given element may be different as the element may have a number of isotopes.


What must every element have different?

Each element has a different number of neutrons.


Which element has a different number of neutrons?

Isotopes are different atoms of the same element with a different atomic mass. This difference is caused by a different number of neutrons.


What property is different in and isotope of an element?

The number of neutrons is different in isotopes of an element. Isotopes of the same element have the same number of protons (which defines the element) but different numbers of neutrons. This variation in neutron number gives rise to different atomic masses among isotopes of an element.
