BEIJING, Feb. 22 (Xinhua) -- Chinese researchers have synthesized two new nucleus isotopes that contain 84 neutrons and 82 neutrons, according to a recent research article published in the journal Physical Review Letters. The nucleus is composed of protons and neutrons. Different numbers of protons...

Isotopes - isotope: atoms of the same element that have different numbers of neutrons - Carbon, as found in nature, is a mixture of isotopes, including atoms of carbon-12, carbon-13, and small amounts of carbon-14. Isotopes atomic weight - The atomic weight of an element is the weighted...
Isotopes同位素 Although an element contains only atoms with the same atomic number, these atoms, however, may have different mass numbers. For example, there are three different kinds of carbon atoms. One has a mass number of 12 and the other two re...
Allotropes are different forms of the same element with distinct physical or chemical properties; Isotopes are atoms of the same element with differing numbers of neutrons.

今日知识点:ISOTOPES Definition: Atoms with ... the same atomic number but different mass number or the same number of protons but different numbers of neutrons. Properties: Chemical properties of isotopes are identical Theory: Relative atomic masses measured by chemical methods rarely produce whole ...
My textbook says that Isotopes have different physical properties as isotopes have different number of neutrons. The difference in the number of neutrons affect the "mass" and the physics properties of a substance is affected by this "mass". This "mass" they are referring to , is it the ...
A family of people often consists of related but not identical individuals. Elements have families as well, known as isotopes. Isotopes are members of a family of an element that all have the same number of protons but different numbers of neutrons. ...
Isotopes of specific elements, such as hydrogen, carbon, and oxygen, have the same number of protons but different number of neutrons in the nucleus. This gives a different atomic weight for a specific element, even though the element maintains the same atomic number. As an example, hydrogen ...
