Different forms of the same element are called isotopes. Isotopes have the same number of positive particles, called protons, and negative particles, called electrons, but differing numbers of neutrons. Neutrons are neutral particles residing in the nucleus of an atom along with protons.Know More
All elements on the periodic table have isotopes, although some are artificially created. Heavier elements tend to have more isotopes than lighter elements.
Although the characteristics of isotopes of an element are generally the same, their masses differ. The mass of an atom consists of the number of protons and neutrons. Some isotopes of an element are heavier or lighter than others, depending on how many more or fewer neutrons the isotope has.
Some isotopes are stable, and others are unstable. Isotopes that are unstable break down, or decay, into other elements, giving off radiation in the process. This decay process allows the atom to become more stable.Learn More
Elements that form anions are elements that need to gain electrons to form a complete octet. Elements in the sixth and seventh periods of the periodic table need to gain one or two electrons to have an octet.Full Answer >
All isotopes of the same element share a common number of protons and electrons, though they vary in their relative numbers of neutrons. All isotopes of a given element are chemically identical, and they form bonds with other elements in the same way regardless of their neutron count or intrinsic stability.Full Answer >
All atoms of the same element have the same number of protons in the nucleus and consequently have the same atomic number. All atoms of the same neutral element have the same number of electrons as well.Full Answer >
Isotopes of the same element differ in the number of neutrons contained within the nucleus of the element's atoms, which causes them to differ in their atomic weights. Some isotopes are more radioactive and unstable than others.Full Answer >
