There are different types of chemical bonds. These are difficult to break and therefore, it is also hard to change. The reason why it's difficult to discover superiority of nature is due to its natural attraction between atoms, ions or molecules that cannot be revoked by man.
I would say the answer is emissions. These are the particles that are not supposed to be present in air but due to the production of different substances from humans daily activities these substances go with the air we breath. Hope this helped.
Everything requires energy to move. If the desk is moving, then it has energy.
Answer : A single carbon atom can form a maximum of <u>Four (4)</u> covalent bond(s).
Explanation : A covalent bond, also called a molecular bond, is a chemical bond that involves the sharing of electron pairs between atoms. These electron pairs are known as shared pairs or bonding pairs.
Formation of covalent bond depends on the number of valence electrons. Electronic configuration of Carbon (C) is :
Valence electronic configuration of C is :
Carbon have four valence electron that means Carbon can form maximum of four covalent bonds.
For example : In methane (CH4) Cabon can share four electrons with four Hydrogen atoms and can form four covalent bonds with 4 H.
Answer:
It is an example of ionic compound and ionic salt
