What of an element are chemically identical but differ in the number of neutrons in the nucleus?
Elements which are chemically identical (have the same number of protons) but different numbers of neutrons are called isotopes.
For example, the element H (hydrogen) has three naturally-occurring isotopes:
- Protium or H-1, with one proton and no neutrons (the most common form)
- Deuterium or H-2, with one proton and one neutron (quite rare)
- Tritium or H-3, with one proton and two neutrons (extremely rare)
Most elements have one distinctly common isotope. For example, the hydrogen in an ordinary glass of water is nearly 100% H-1, while the oxygen is nearly 100% O-16 (with 8 protons and 8 neutrons). Oxygen does occur naturally with 2 extra neutrons (O-18) and 1 extra neutron (O-17), but these isotopes are quite rare.
What else can I help you with?
Are all atoms of a given element identical to one another and different from atoms of other elements?
No. Some may have different numbers of neutrons. Atoms of the same element (atoms with the same number of protons in the nucleus) may have different numbers of neutrons, and so will have different masses. As an example, chlorine is a mixture of different isotopes with some of the atoms having different neutrons numbers.
What is in hydrogen nucleus?
In a Hydrogen nucleus there is a proton. Hydrogen is the only element to not have a neutron in it's nucleus.
Isotopes are atoms of the same element that have different atomic masses?
Yes. An element is defined by its atomic number, the number, or the number of protons in its nucleus. When an atom has more or less neutrons it is still the same element, but a different isotope of that element.
Finding the number of neutrons in an element?
To find the number of neutrons in an element, subtract the atomic number (number of protons) from the mass number (sum of protons and neutrons). Neutrons do not carry a charge and help stabilize the nucleus of an atom.
How is the atomic number and mass number different?
The atomic number is the number of protons in the nucleus of an atom of any given element. The mass number is the number of protons and neutrons in the nucleus of an atom of an isotope of an element.
Do isotopes have a nucleus?
Yes. Isotopes are simply normal elements with a different number of constituent neutrons in their nucleus. All isotopes have a nucleus with an identical number of protons to its element.
What structural feature is different in isoptopes of a particular element?
Isotopes of a particular element have the same number of protons but a different number of neutrons in their nucleus. This difference in the number of neutrons gives isotopes different atomic mass values.
Where is the neutrons located at on an element on the pt element?
All neutrons (of all elements) are located in the nucleus (as all ptotons are)
Which solid element has 135 neutrons in its nucleus?
The element with 135 neutrons in its nucleus is Xenon, which has an atomic number of 54.
What are the basic unit of a chemical element called?
many identical atoms Answer is= Atoms.
What is something and atom and isotope have in common?
Isotopes are different forms of the same element which have different numbers of neutrons in their atomic nuclei. A given element is identified by the number of protons in its nucleus; that's its atomic number. Two different isotopes of the same element have the same number of protons, but each has a different number of neutrons in its nucleus. Different isotopes of the same element are chemically the same.
How are isotopes the same but different?
Isotopes are different forms of the same element which have different numbers of neutrons in their atomic nuclei. A given element is identified by the number of protons in its nucleus; that's its atomic number. Two different isotopes of the same element have the same number of protons, but each has a different number of neutrons in its nucleus. Different isotopes of the same element are chemically the same.
What element is the number of protons and neutrons in the nucleus?
All elements have neutrons and protons within the nucleus.
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.
An atom of any element must contain?
An atom of any element must contain protons, neutrons, and electrons. The number of protons in the nucleus determines the element's identity, while the neutrons and electrons help determine its stability and reactivity.
The nucleus of a helium atom is identical to what?
The nucleus of a helium atom is identical to an alpha particle, which consists of two protons and two neutrons.
How many neutrons are in the nucleus of the element 'p'?
16
