what kind of element could definitely be electrovalency and why
Answers
Answer:
Electrovalency is the type of chemical bonding, that is established by the actual transference of one or more valence electrons, from a metallic atom to a non-metallic atom, so that each of the 2 elements can attain the stable electronic configuration of their respective nearest inert elements in the periodic table. This results in the formation of oppositely charged ions which are held by electrostatic force of attraction and they in turn form an electrovalent compound. For example, Na and Cl will form an electrovalent compound NaCl. So first Na, being a metal, will give away 1 electron to attain the stable state of Neon, its nearest inert element. Then Na will become. That 1 electron will be accepted by Cl so that Cl can attain the stable state of Argon, its nearest inert element. Cl will thus become. So Na+ + Cl- = NaCl Electrovalency is a measurement of the net electric charge of an ion and is used when balancing chemical reactions. Electrovalency is related to the concepts of electronegativity and valence electrons, and indicates the number of electrons necessary for an ion to have a balanced electric charge. Atoms that have an almost full or almost empty valence shells tend to be very reactive. Atoms that are strongly electronegative often only have one or two missing electrons in their valence shell, and frequently bond with other molecules or gain electrons to form anions. Atoms that are weakly electronegative have relatively few valence electrons that can easily be lost to atoms that are strongly electronegative. As a result, weakly electronegative atoms tend to lose their electrons and form cations.+2+3+−2−3−+3−
Answer:
electrovalency (plural electrovalencies) (physics) The net electric charge on an ion. (chemistry) The number of electrons gained or lost during the formation of an ionic bond.
