Describe Electrovalent bond.​

The chemical bond formed by the transfer of electrons from the valence shell of one tom to the valence shell of another atom is called electrovalent bond or ionic bond ad the valency is electrovalency. The compounds which are formed as a result of lectrovalent bonding are called electrovalent compounds or ionic compounds.

Explanation:

ectrovalent bond is formed between two atoms in which one atom belongs to a etal while the other to a non-metal. The metal atom loses its valance electron to tain stable electronic configuration and gains positive ion or cation. On the other nd, the non-metal atom gains electrons from the metal to form stable negative ion anion. The atom of an element which has less than 4 electrons in its valence shell has tendency to lose electrons whereas the atom which has more than 4 electrons in its lance shell has a tendency to gain electrons to attain the inert gas configuration. As a sult, these atoms acquire electrical charges; called ions. Usually metal atoms lose ectron (s) and gain positively charged whereas non-metal atoms usually gains electron and acquires a negative charge. These two oppositely charge ions i.e. cation and mion are bonded together by the force of attraction to form the ionic bond.

the chemical which transfer elements totally

answer: c. the experiment shows that the red substance experienced a chemical change.

explanation: chemical change is the change in which chemical composition of the substance changes. physical change is the change in which there is no change in chemical composition.

chemical changes are accompanied by following changes:

a) precipitate formation

b) energy is released or absorbed

c) formation of bubbles

d) change in color

as it is given that the red color has disappeared and there is production of gas, it means the red substance has undergone a chemical change.

e

distance, luminosity, brightness, radius, chemical composition, and temperature
