Chemical Bond worksheet

Chemical bond can be defined as the force of attraction between two atoms which holds atoms and ions together in a unit. Electrovalent bond is a chemical bond in which atom loses an electron to form a positive ion and the other atom gains the electron to form a negative ion.

Some of the questions related to Chemical bonding are listed below, with their answer.


1.An bond is formed under which condition mainly?

(a)    donate e^- to non-metal

(b)   Energy must be released during bond formation

(c)    Energy must be adsorbed during bond formation

(d)   Metal share e^- with non-metals


2. Which is not a feature of an ionic compound:

(a)    Have  a definite geometry

3. Which is not correct here:

(a)    ionic  solids conducts electricity due to presence of free ion

4. NH_4Cl has which type of bond:

(a)     Ionic

(b)   Co-valent
