2025年1月18日 · An isotope is one of two or more species of atoms of a chemical element with the same atomic number and position in the periodic table and nearly identical chemical behavior but with different atomic masses and physical properties.

2019年9月13日 · Isotopes are forms of an element that have different numbers of neutrons. All isotopes of an element have the same atomic number and number of protons , but they have different atomic masses from each other.

Isotopes are distinct nuclear species (or nuclides) of the same chemical element. They have the same atomic number (number of protons in their nuclei) and position in the periodic table (and hence belong to the same chemical element), but different nucleon numbers (mass numbers) due to different numbers of neutrons in their nuclei.

The isotope of an element can be defined as one of the several variants of the specific chemical element which holds the same number of protons and electrons as the atomic number of the element but holds a different number of neutrons when compared to the other variants (isotopes) of …

2022年8月19日 · Isotopes are forms of a chemical element with specific properties. Like everything we see in the world, isotopes are a type of atom, the smallest unit of matter that retains all the chemical properties of an element.

2024年4月2日 · What are Isotopes? Isotopes are those elements in which the number of protons in an atom of a given element is constant, while the number of neutrons might vary. For example, C-12, C-13, and C-14 are examples of isotopes of carbon, where all of them have six protons but six, seven, and eight neutrons, respectively. What are Isotopes of Hydrogen?

2020年2月4日 · Isotopes are samples of an element with different numbers of neutrons in their atoms. The number of protons for different isotopes of an element does not change. Not all isotopes are radioactive. Stable isotopes either never decay or else decay very slowly. Radioactive isotopes undergo decay.

2024年9月22日 · Isotopes are atoms of the same element that have an identical number of protons but different numbers of neutrons. Some important characteristics of isotopes are as follows: (1) Same Atomic Number:

2023年6月9日 · Isotopes are a vital concept in the study of atoms. Chemists, physicists and geologists use them to make sense of our world. But before we can explain what isotopes are — or why they're so important — we'll need to take a step back and look at atoms as a whole.

What is an isotope? An isotope is an atom that has the same number of protons and a different number of neutrons. The atom is still considered the same element (still contains the same number of protons) as before but will have a different mass.
