How do elements differ ions isotopes?
An atom is the smallest part of an element that can exist either alone or in combination with other atoms. Isotopes are atoms that have the same number of protons but different numbers of neutrons. An ion is an atom or molecule with a positive or negative charge. A cation is an ion with a positive charge.
What elements are in ions?
Cations (positively-charged ions) and anions (negatively-charged ions) are formed when a metal loses electrons, and a nonmetal gains those electrons….Positive and Negative Ions: Cations and Anions.
| Family | Element | Ion Name |
|---|---|---|
| Sodium | Sodium cation | |
| Potassium | Potassium cation | |
| IIA | Beryllium | Beryllium cation |
| Magnesium | Magnesium cation |
How are ions and isotopes made?
Neutral atoms of an element contain an equal number of protons and electrons. The number of neutrons can vary to produce isotopes, which are atoms of the same element that have different numbers of neutrons. The number of electrons can also be different in atoms of the same element, thus producing ions (charged atoms).
Can isotopes be an ion?
Isotopes are atoms that have the same numbers of protons but different numbers of neutrons. An ion is an atom that has gained or lost electrons, so it now has more or fewer electrons than it does protons. All atoms are isotopes and if an isotope gains or loses electrons it becomes an ion.
How do you identify isotopes?
Isotopes are identified by their mass, which is the total number of protons and neutrons. There are two ways that isotopes are generally written. They both use the mass of the atom where mass = (number of protons) + (number of neutrons).
How do you identify ions?
An ion is denoted by writing its net negative charge in superscript immediately after the chemical structure for the atom/molecule. Conventionally the net charge is written with the magnitude before the sign; the magnitude of singly charged molecules/atoms is generally omitted.
Can an atom be an ion?
If an atom has the same number of protons and electrons, it is electronically neutral. However, if the total number of electrons does not equal the number of protons, the atom has a net electrical charge. Any atom or molecule with a net charge, either positive or negative, is known as an ion.
What are types of isotopes?
There are two main types of isotopes, and these are radioactive isotopes and stable isotopes. Stable isotopes have a stable combination of protons and neutrons, so they have stable nuclei and do not undergo decay.
How are isotopes created?
Isotopes can either form spontaneously (naturally) through radioactive decay of a nucleus (i.e., emission of energy in the form of alpha particles, beta particles, neutrons, and photons) or artificially by bombarding a stable nucleus with charged particles via accelerators or neutrons in a nuclear reactor.
