When a sodium atom donates one outer shell electron to a chlorine atom, the sodium becomes an ion with a _____ charge. positive Ionic bonds are formed between ____________ .
Species with overall positive charges are termed cations, while species with overall negative charges are called anions. Remember that ions are formed only when electrons move from one atom to another; a proton never moves from one atom to another.
An anion (−) (/ ˈ æ n ˌ aɪ. ən / ANN-eye-ən, from the Greek word ἄνω (ánō), meaning "up" [13]) is an ion with more electrons than protons, giving it a net negative charge (since electrons are negatively charged and protons are positively charged).
Ion, any atom or group of atoms that bears one or more positive or negative electrical charges. Positively charged ions are called cations; negatively charged ions, anions. Ions migrate under the influence of an electrical field and are the conductors of electric current in electrolytic cells.
Atoms that lose electrons acquire a positive charge because they are left with fewer negatively charged electrons to balance the positive charges of the protons in the nucleus. Positively charged ions are called cations. Most metals become cations when they make ionic compounds.
Atoms or groups of atoms that possess a net electrical charge are called ions; they can have either a positive charge (cations) or a negative charge (anions). Ions can consist of one atom (monatomic ions) or several (polyatomic ions).
20 lis 2021 · Examples of Ions. Chemical notation indicates ions by following an element symbol or chemical formula with a superscript that shows whether a charge is positive (+) or negative (-) and the amount of charge. If an electrical charge is 1, only list the “+” or “-” symbol. Here are some ion examples: H+; Ca 2+ Fe 2+ Fe 3+ Cl – P 3-NH 4 ...
