APAKAH MAKSUD ELECTROVALENCY dalam CORSICA?
Electrovalency
Electrovalency adalah jenis ikatan kimia, yang ditentukan oleh pemindahan sebenar satu atau lebih elektron valensi, dari atom logam ke atom bukan logam, supaya setiap elemen 2 dapat mencapai konfigurasi elektronik yang stabil dari masing-masing terdekat unsur lengai dalam jadual berkala. Ini mengakibatkan terbentuknya ion bermuatan bertentangan, yang dipegang oleh tarikan daya elektrostatik dan seterusnya membentuk sebatian electrovalent. Sebagai contoh, Na dan Cl akan membentuk sebatian electrovalent NaCl. Oleh itu, Na pertama, sebagai logam, akan memberikan 1 elektron untuk mencapai keadaan stabil Neon, unsur inert terdekatnya. Kemudian Na akan menjadi. Bahawa 1 elektron akan diterima oleh Cl supaya Cl dapat mencapai keadaan stabil Argon, unsur inert terdekatnya. Oleh itu, Cl akan menjadi. So Na + + Cl- = NaCl Elektrovalensi ialah ukuran cas elektrik elektrik ion dan digunakan apabila mengimbangi tindak balas kimia. Elektrovalensi berkaitan dengan konsep elektronegativiti dan elektron valensi, dan menunjukkan bilangan elektron yang diperlukan untuk ion untuk mempunyai cas elektrik yang seimbang.
Definisi electrovalency dalam kamus Corsica
Takrif elektrovalensi dalam kamus adalah valensi bahan dalam membentuk ion, sama dengan bilangan elektron yang diperoleh atau hilang.

Types of Valency There are two types of valency : Electrovalency and Covalency.
If an element combines by the loss or gain of electrons to form electrovalent
compounds (or ionic compounds), its valency is known as electrovalency, and if
an ...

Variable Electrovalency The electrovalency of an element is equal to the number
of electrons lost or gained by its atom during the formation of ionic bond. The s-

Introduction to Inorganic Chemistry
The concept of electrovalency can be extended to atoms in semi-polar molecules
. We saw in Chapter 5 that the charge distribution in the HF molecule is
approximately H0.5+F0.5−. Thus if, as for an ion, we set the electrovalency of an
atom in ...

Typical electrovalency is most commonly foundin compounds derived
fromelements situated inthe groups adjacentto the inert gases. Thus a sodium
atom (1s2,2s2,2p6,3s1) may lose the electron occupying the 3s orbital, giving a
sodium ion.
