Atoms with a large electronegativity are atoms that are greedy for electrons. Highly electronegative atoms are the ones that are most commonly involved in ionic bonding. This should make sense; this type of bond is all about taking electrons from other atoms. What Is an Ion? Recall that electr...
IONIC BONDING Some elements tend to gain electron(s) readily while others tend to lose electron(s) (low I.E.) When an active element (metal) reacts with an active non-metal), electrons are transferred from the metal to the non-metal. Atoms of the non-metal become anions while the met...
3.1: Two Types of Bonding 1. Define the octet rule. 2. Describe how ionic bonds are formed. Chemists have concluded that atoms are especially stable if they have eight electrons in their outermost shell. This useful rule of thumb is called the octet rule, and it is a key to understanding...

Bonding in Ionic CompoundsIn its purest form, ionic bonding is not directional. It can be regarded as simple positive-negative Coulombic attraction between point charges. This is different from covalent bonding, in which electrons are shared by atoms, forming directional bonds....
Ionic bonding Day #2 Learning goals We are learning to identify ionic compounds. We are learning to name ionic compounds. We are learning to write chemical formulas for ionic compounds. Recall An ionic bond occurs between a metal and a non-metal. The metals lose electrons to become cations....

It seems that despite the presence of undissolved PVA particles, the overall hydrogen bonding density in the 25 % PVA hydrogel may still be higher compared to the 10 % and 15 % PVA hydrogels. Furthermore, a gradual normalized moisture loss per 1 % decrease in RH is around 0.66 % for ...
