Answer: An ionic bond is a type of chemical bond formed through an electrostatic attraction between two oppositely charged ions. Ionic bonds are formed between a cation, which is usually a metal, and an anion, which is usually a nonmetal. A covalent bond involves a pair of electrons being shared between atoms.

Answer:
boyles law
Explanation:
volume is inversely proportional to pressure
<u>Answer:</u>
<em>The rule is called as Octet Rule.</em>
<u>Explanation:</u>
Chemical bond: the attractive force which holds the atoms together in a molecule. Except noble gases He,Ne,Ar,Kr and Rn all other atoms have less than 8 electrons in its outer shell and unstable.
In order to attain stability Atoms loses or gains or shares electron to get 8 electrons in its outer shell which is called noble gas configuration.
“Octa” means 8.
The respectable gases are the main arrangement of components that have 8 electrons in their furthest shells and that is the reason they are steady and lifeless. The octet principles express that a component must have 8 electrons in its furthest shell as to be steady.
Its D for the second energy level, but the first energy level is 2.
